When it comes to keeping your beard looking nice and neat, instead of making frequent trips to the barber, having a reliable and predictable beard trimmer handy can be an indispensable tool for the ultimate beard styling.

In this guide, we will help you find the best beard trimmer for your own unique facial hair.  To do this, we will be taking a look at a variety of features and abilities of today’s most popular beard trimmers and couple that with our in-depth reviews.

Beyond the reviews, we will also share with you a few tips on how to get the most from your new beard trimmer.

Let’s dive in.

What to Know When Buying a Beard Trimmer

As we got into the details of comparing different beard trimmers, we identified a staggering 11 key factors that you should think about before making your purchase.  While this may seem a bit overwhelming to some – don’t worry, we will go through each one of them quickly so you can find the best beard trimmer to meet your needs:

1. Number of Length Settings

Many modern beard trimmer brands offer dials built into the handle of their device.  This added feature allows you to fine-tune the trimmer to your exact length.  This is a great feature for those men who prefer to keep their beards at the same length every single day.

Now dials for beard trimmers do come in two main varieties – digital and manual.  Here’s a quick rundown on each:


Beard trimmers with a built-in memory system can store your preferred length setting every time you shave.  This easy to read display makes finding your preferred length a breeze.

Digital beard trimmers do require the addition of a motor which can make it much easier to fine-tune the trimmer to a particular setting.  We found that some trimmers were able to make small 0.1mm adjustments.


Beard trimmers with a manual dial give that tactile mechanical feel that many men often love.  Relying on manual operation rather than a motor ensures fewer moving parts and wiring – which may translate to a lower price or longer life.

Naturally, manual dials aren’t able to fine-tune to a specified length setting as easy as a digital dial.  Therefore, you will find that they often go in 0.2mm increments.

2. Precision

Building off the previous section, popular beard trimmer brands have improved in cut-length tremendously in recent years.

This greatly improves the versatility of beard trimmers and bridges the gap immensely with another related tool – stubble trimmers.

During our research, we found that the following lengths were the most common minimum length settings:

  • 2mm
  • 5mm
  • 1mm

Just for context, it is estimated that the beard grows in at a rate of about .33mm per day (or about 10mm per month).  A 0.2mm length cut is truly a 5 o’clock shadow cut.

On the opposite end of the spectrum, beard trimmers can extend their comb to several millimeters in length.

Common length limitations that we found in beard trimmers were the following:

  • 18mm
  • 20mm

Anything greater than this length should be maintained with shears instead.

3. Styling Versatility

Given that beard trimmers are closely related in both size and function as hair clippers, many men may try to find a device that can accomplish several tasks at once.

As we found in our research, many beard trimmers may be capable of grooming the following:


While the mustache is technically just an extension of your beard, most beard trimmers should have no problem when it comes to cutting and maintaining a mustache.

The biggest feature you will want to look out for here is the head size of the trimmer itself.  Unfortunately, many beard trimmers tend to carry a bulky head – which makes navigating the tight contours around your upper lip and nose quite difficult.  Therefore, a beard trimmer with a slightly narrow head should prove useful when trimming the mustache.


While “manscaping” is no longer taboo like it was only a few years ago, many men are starting to use their beard trimmer below the neckline.  Beard trimmers should have no problem cutting through the naturally coarse and thick hair of your body.

Now if you want a beard trimmer to make quick work of your body hair, we would recommend going with a beard trimmer that has a wider head.  It will allow you to cut more hair in fewer passes.  Secondly, a beard trimmer with body attachment combs is also preferred as they often have smooth and rounded edges for comfort – especially important if cutting below the belt.


Whether you are doing a bit of a trim on yourself or someone else, using a beard trimmer as a stand-in for a hair trimmer can work in some instances.  However, the biggest reason why these two products are separate categories has to do with motor power.

Hair trimmers often rely on powerful electromagnetic motors.  These strong motors allow for clean fades and cuts that don’t look choppy.  If you use a beard trimmer on your hair, we recommend that it is only best for precision details.

4. Corded vs. Cordless Operation

Beard trimmers come in two main varieties – corded and cordless.  While the obvious feature between both of them is their mobility, here we wanted to take a quick minute to discuss both a bit further as there are some important considerations here:


Nearly all consumer-based beard trimmers are cordless. This allows for easy handling of the device and one that is very travel-friendly.

The biggest difference between corded and cordless beard trimmers will be motor power.

Relying on a Ni-MH or Li-Ion battery, cordless beard trimmers are a bit weaker than corded beard trimmers.  Therefore, the total trim time may be significantly longer.  While likely not an issue you if you only trim your beard on occasion, men who trim daily may seek more efficient grooming habits.

Another nice feature of cordless beard trimmers is that they can be used in areas outside or around the bathroom (trimming beard while standing in the tub) which can make the cleanup while using this device a bit easier.


As we touched on previously, corded beard trimmers are often the more powerful of the two trimmer types.  Usually relying on a powerful electric magnetic motor, corded beard trimmers will cut the hair quickly and efficiently.

With fewer passes required, corded beard trimmers are ideal for professional barbers or men who trim daily and want a higher level of performance.

Naturally, there are limitations to this beard trimmer including mobility (you are restricted based on how long the cord is), international voltage differences, and a lengthier cleanup process (given that it’s corded, you can’t simply rinse the trimmer under water).

5. Battery Technology

For those men who are sold on the conveniences of the cordless beard trimmer, we wanted to go a bit deeper and talk about battery life – as it can be a huge factor on whether or not you will be satisfied with your purchase.

Here’s what you need to know about both popular battery types found in beard trimmers:


Lithium-ion (li-ion) batteries are found in many of today’s devices.  Able to carry a charge much longer compared to previous generation battery technology, it delivers reliable and efficient performance.

However, what truly sets this battery apart from other types (including Ni-MH) is how fast it takes to gain a charge and how long it will last.

Usually able to get a full charge in under an hour (typically around 45 minutes for most beard trimmers) and last for about 60 to 90 minutes (depends on the size of the battery and milliamps among many other things), this battery performance is preferred by a lot of men, and here’s why:

Whether you are traveling overseas or simply like to have a clutter-free bathroom countertop absent of cables, the long battery life per charge means you don’t have to worry about plugging in your trimmer every time you are finished.

As a quick back of the envelope calculation, if it takes you only three minutes to trim your beard every day and you decide on a beard trimmer with a 60-minute run time on a full charge, you would only have to charge once every 30 days.  But if you skip a day or two (and perhaps even weekends), you can go substantially longer between charges (usually a couple of months at most).


Another common battery type that you will find in cordless beard trimmers will be Nickel-Metal Hydride.  This older battery type performs at a significantly lower efficiency rate and takes a substantial amount of time to charge.

Based on our research, we found that beard trimmers which rely on Ni-MH batteries will take several hours (usually around 8) to gain a full charge, and can only operate for about 30 to 45 minutes at most.

So why do men ever buy a beard trimmer with a Ni-MH battery?

We believe it is due to a mixture of their lower price point along with a lack of knowledge (at no fault to the man who is buying the device).

Companies that sell Ni-MH powered beard trimmers often never exclaim that this is the type of battery used in their device or they get vague on advertising charge time.

We found that beard trimmers relying on this dated battery technology are often cheap knockoffs that are only out to make a quick dollar at the expense of the consumer.  We will talk more about how you can spot these bad actors in a few minutes.

6. Ease of Use

As you get comfortable using your beard trimmer on a regular basis, there will, of course, come a time where you will need to take it apart and clean out the blades.

Now if you are one that likes to clean their trimmer after every use to get an optimal cut, then you will want to know about the three main variants of beard trimmers when it comes to cleanup:

Fully Washable/Waterproof

Fully washable or waterproof beard trimmers are great when it comes to both versatility and convenience.  Whether you are a guy that likes to trim their beard while taking a shower or simply want to get a deep clean on the trimmer after every use, washable beard trimmers will make perfect sense.

Unfortunately, there are few beard trimmers that fall into this category.  Therefore, if you want these cleaning conveniences, you may need to make some compromises when it comes to other features (i.e. length settings, precision, brand, voltage, etc.).

Washable Head

Most modern beard trimmers will fall into this category – washable trimmer head but the body can’t get wet. While trimming your beard in the shower isn’t preferred by men, unless you have a quality fogless shower mirror, when it comes to clean up, this type of head makes things a bit easier.

With water able to easily get into every crevice of the cutting head, you will be able to flush out any clippings that may be inhibiting the performance of the trimmer itself.

While a beard trimmer with a washable head likely isn’t at the top of the list of preferred features for many men, it’s one that you will instantly love after the first time you clean it.

Dry Brush Only

The last cleaning option on our list will be a beard trimmer that is unable to get wet (i.e. cleaned with a dry brush only).  We find this to be true of all corded beard trimmers (for obvious safety reasons) along with many of the vacuum beard trimmers on the market.

While not nearly as convenient or versatile as a waterproof or washable head beard trimmer, dry brushes take a bit more labor and may cause a bit of a mess.

Therefore, we recommend this cleaning option in a beard trimmer for those men who don’t mind dedicating a few extra minutes and getting their hands a bit dirty.  You should also be fine with a few clippings being found around the counter or sink area as they will inevitably popup.

7. Voltage

When buying a beard trimmer, very few men ever put weight on the actual voltage capacity of the trimmer itself (hence why it’s much lower here on our list.

However, should you find yourself traveling internationally for work or you simply are living in the U.S. temporarily, a beard trimmer capable of handling higher voltage requirements may be a consideration of yours.

In order to make sure that you get a compatible beard trimmer to be used on higher voltage outlets, you will want to read either the product descriptions or the company website for technical specifications.  Specifically, you will want to look for a beard trimmer that can be used on either 120V or 240V outlets.

8. Extras

While beard trimmers are largely the same from one brand to another, there are some that may offer unique extras that might pique your interest.

Therefore, we wanted to highlight a few notable features that we came across in our research:

Vacuum Handles

Using a beard trimmer can be a messy endeavor for some men – especially those with thick and full beards.

While companies have tried to capitalize on this problem by selling beard bibs (yes that’s really a thing – and yes, you might have seen it on Shark Tank), some beard trimmer companies try to make things a bit easier through additional cleanup features – with the most common one being a vacuum installed into a handle.

Designed to pull the clippings into the collection tray, this unique design can lessen the amount of time required during clean up, especially if you can’t rinse the trimmer under water to clean.

Now when it comes to performance and expectations, these trimmers are never perfect.  Designed to catch most clippings (we found about a 90% catch rate), there will still be clippings that’ll make it to your bathroom countertop or sink.

While not perfect in collecting all the cut facial hair, this design is fairly effective.

We found that most men who were disappointed in this design were largely due to missed expectations (they were hoping that they could use this trimmer and not worry about cleanup).

Attachment Combs

Whether you are looking to achieve some subtle fades in your beard, or perhaps you are wishing to use a beard trimmer on a longer beard, attachment combs are a nice add-in.

Coming in a variety of lengths, attachment combs can also provide a protective barrier should you want to use the beard trimmer on other parts of your body.

Unless you buy a corded beard trimmer, most beard trimmers don’t allow you to purchase replacements.

Ear, Nose & Eyebrow Trimmers

In addition to attachment combs, some beard trimmers have extensions that can be used to groom your ear, nose, or eyebrows.

This can be a great addition for those men looking to manage some wispy or embarrassing hairs on their face.  However, it’s worth noting that beard trimmers being used for such small grooming areas can be a bit tough given their larger heads.  While it works as a great substitute, we still don’t think these extendible tools are as good as some of the best ear, nose or eyebrow trimmers we recently reviewed.

Travel Lock

When traveling extensively with a cordless beard trimmer, having a travel lock feature can be a lifesaver as it can prevent any unexpected dead batteries.

Unfortunately, not all beard trimmers have this feature.  Therefore, if you like to bring your beard trimmer with you on the road or to the gym, a digital or physical travel lock to prevent battery drainage will be preferred.

Blade Construction

As you will see in both the reviews and on product listing pages, the trimming blades used on beard trimmers are usually either one of the following:

  • Stainless steel
  • Carbon steel

Both of these have their own unique properties that are worth knowing about:

Stainless Steel

Designed to naturally resist rust and corrosion, this variant of steel is perfect for use in the bathroom and on a beard trimmer.  We recommend this over carbon steel, especially if the head of the trimmer is washable as it will lead to a much longer lifespan given its natural properties.

Carbon Steel

While sharper than stainless steel, carbon steel is prone to both rust and corrosion.  Beard trimmers made with this metal variety should be oiled often and stored outside the naturally humid environment of the bathroom.  Men that favor this steel want greater precision in their cutting blade.

9. Brand

After its introduction by Wahl in 1984, beard trimmers have become a critical part of a bearded man’s grooming routine for several decades (source).  However, in the past few years, many unknown brands have entered this popular space and have begun introducing much more affordable offerings.

Unfortunately, with so many new brands, quality and performance have certainly come into question.

Therefore, when shopping at online retailers, sifting through all the options can be quite difficult.  Therefore, we wanted to share with you a few tips to help make the selection process easier:

  1. Go With A Known Brand: While we aren’t one to usually dismiss startups when it comes to beard trimmers, they are a bit complex compared to other grooming tools. Therefore, more research and development are required.  Unfortunately, with many small brands, they often skip this process and will rely on cheap generic import products that break.
  2. Check for A Warranty: Another feature absent of many of these small online brands is that there is no warranty to back up their product. Beyond a ’30 Day Money Back Guarantee’ (which is the standard return window for most online retailers), you will want to go with a beard trimmer that stands by their product with at least a one-year limited warranty.
  3. Check The Website: You can tell a lot about a company when you visit their website (or lack thereof). If you decide to go with a company you haven’t heard of before, make sure that they have a legitimate website, contact number, and more – if they don’t pass the sniff test, don’t buy from them.

The short, just know this:

Trusted brands like Panasonic, Philips Norelco, Braun, and more have built a legacy on providing quality products that perform well.  Many unknown brands online are out to make a quick buck in any way possible.

Therefore, if you don’t want to find yourself researching for a new beard trimmer in a few short months – go with a respected brand that stands by their product.

10. Online Ratings

As an extension to the previous section, online ratings when it comes to beard trimmers are abnormally skewed.  Whether it’s overly positive or negative, heavy manipulation appears to be going on in this market.

Therefore, we would recommend that you try and dismiss most of the 5 or 1-star reviews and take a look at the 2, 3, and 4-star reviews.  Here you will find more detailed feedback about the product and if it will meet your expectations.

11. Price

Having a great looking beard shouldn’t cost you several hundred dollars – and it won’t.  Based on our research, we found that most of the best beard trimmers carried an average price point anywhere between $50 and $100.

Beard trimmers under $50 often featured compromises that inhibited performance (i.e. Ni-MH battery, limited length settings, etc.) and those priced higher than $100 usually didn’t provide any substantial performance increase.

The Best Beard Trimmers of 2021 Reviewed

1. Best for Long Beards: Remington Long Beard Trimmer

This beard trimmer by Remington is not only perfect for those looking to groom a longer beard but also includes a variety of extras to make sure that you look and feel your best.

While we will get to the extra details in just a minute, let’s first take a look at the beard trimmer itself:

Relying on a lithium-ion battery, this cordless beard trimmer features a 120-minute run time (requires a lengthy 4-hour charge) and comes in a few different length settings.

For those with long beards, this Remington trimmer can extend to 35mm (or 1.38”) – making it one of the longest on the market.

Beyond just allowing for trimming of longer beards, this trimmer is plenty versatile to work with shorter beards as well by being able to cut down to 1.5mm (about .06”).

Length settings aside, the trimmer has a manual wheel for dialing in the length setting (only when the small comb is attached) that allows you to fine-tune the length for a shorter beard.

The trimmer also doubles as a detail trimmer –with a pop-up and extended cutting comb that can work the details of your face.

While we don’t think it will be nearly as effective as a true ear, nose or eyebrow trimmer – it should be able to work in a pinch.

As far as the extras included, this beard care kit by Remington also includes shears and a brush.

The shears are particularly important here as it allows for greater control of grooming for really long beards.

In addition, you can use shears to give your bears a more tapered look – which should look and present well.

The beard brush is on par with some of the premium beard brushes we reviewed and should do a great job at both straightening your beard prior to trimming along with helping with the distribution of critical beard care products like beard oil or beard balm.


  • Works well for those with long beards
  • Includes important beard care tools
  • Fairly priced


  • Doesn’t go as low as some may prefer
  • Lengthy wait time for full charge

What You Need To Know

Should you have a long beard or you simply want versatility in settings, this beard trimmer by Remington is a great pick. The wide size range from 1.5mm to 35mm is unprecedented in this category. The inclusion of shears and a beard brush also make this a perfect pick for those men looking to enhance their beard care routine.

2. Best Beard Trimmer For Stubble: Braun BT3040 – Stubble Beard Trimmer

There is something about the precision German engineering and shaving that really work well together. While Braun is now a wholly-owned subsidiary of Proctor & Gamble (source), they still draw upon their rich heritage of smart and sensible design.

This couldn’t be truer than with the Braun (model BT3040) we reviewed.  With a simple on/off switch and a mechanical turn dial for length settings, it’s a beard trimmer that gets right to the job at hand.

Beyond the design aesthetics, the primary reason why this trimmer made our list was due to a variety of factors:

  • Length Settings: Able to cut down to 0.5mm, it provides one of the closest shaves available for a beard trimmer. Competing directly with many of the best stubble trimmers we reviewed, the 0.5mm cut will provide a nice and dark 5 o’clock shadow that so many women love (according to our recent survey).  Now if you aren’t looking to cut to a stubble or you simply want to grow a longer beard, this trimmer can cut up to 20mm in length (or about 0.8”).
  • International Voltage: Whether your work demands it or you are traveling for leisure, the BT3040 can work on outlets between 100V and 240V – making it a travel-friendly beard trimmer.
  • Fully Washable: Cleaning beard trimmers can be a messy process – especially if you use a dry brush. While this beard trimmer by Braun includes a stiff bristle dry brush for detailed cleaning, the trimmer is fully washable so you can simply rinse it under water after you finish.
  • Stainless Steel Blades: Relying on stainless steel blades, this beard trimmer should last a lifetime as the metal will never rust or corrode in the naturally wet environment of the bathroom. While not as sharp as carbon steel, it will get the job done well.

The weakest feature of this beard trimmer will be the battery life.  While not advertised by Braun, we believe the BT3040 relies on a Ni-Cad battery.  In order to get a 60-minute run time, you will need to charge it for a lengthy eight hours (i.e. overnight).

To combat this drawback, Braun smartly allows this trimmer to be used while corded.


  • Easily cuts down to a nice shadowy stubble
  • Travel-friendly (100-240V)
  • Washable head for easy cleanup


  • Long charge time

What You Need To Know

While the lackluster battery may be the biggest drawback to this beard trimmer, all the other features of this trimmer are strong. The simple and no-nonsense design coupled with a mechanical dial for a perfect length setting make this a well-rounded and affordable stubble trimmer (that’s also a great beard trimmer).

3. Best Cordless Beard Trimmer: Wahl 9818 Cordless Beard Trimmer

A fixture in barbershops around the world, U.S.-based Wahl makes a variety of cutting tools that deliver a strong performance.

When reviewing their cordless beard trimmer (Wahl 9818), there were several features that really stood out among many other competitors.

Here’s what they were:

Long-Lasting Battery Life: The strongest feature for this beard trimmer by Wahl will undoubtedly be the battery life.  With a one-hour charge, this beard trimmer has a four-hour run time – giving it one of the longest battery run times on the market.  Now if you just need to make a quick trim of your beard, a charge of only one minute should be just enough as it can provide a three-minute run time.

Attachment Guards: Now many of the beard trimmers reviewed only contain one or two attachments.  However, the Wahl 9818 includes an impressive 12 attachments – making it work for a variety of beard lengths.  Now a major drawback to this is that the trimmer doesn’t include a dial onto the handle.  While likely not a deal-breaker for many, it’s worth noting as you will need to find the appropriate guard prior to trimming.

Travel-Friendly: When it comes to traveling with this beard trimmer, it has a couple of features that men commonly look for, and that is international voltage compatibility along with a travel power lock – the Wahl 9818 has both.  Able to work with voltages between 100V and 240V, you won’t have any issues using this trimmer overseas.  Furthermore, simply holding down the power button for 5 seconds will enable the travel lock.

Nose and Ear Trimmer: For men who don’t want separate trimmers for different purposes – this trimmer also comes included with a detail and nose trimmer.  Therefore, with a simple swapping of the heads, you can remove any embarrassing hairs that may have popped up.

Warranty / Made in the USA: Very rarely nowadays do we come across electronic devices that are made in the U.S.  With so much stuff being made abroad, we had to check twice to make sure we weren’t mistaken.  For the patriots out there, this trimmer is made in the U.S. from a blend of both domestic and imported parts.  Furthermore, Wahl stands by this trimmer and offers a 5-year warranty.

Now as great as this trimmer may be, there are a few minor drawbacks that are worth noting.

The most notable drawback is that this is a dry-use only beard trimmer.  Therefore, cleaning will require the use of a brush (cannot run it under the water).  While we touched on it briefly above, there is no length setting dial on this trimmer – you must change the attachment comb for every length setting.


  • Best in class battery run time
  • Made in the USA
  • Several attachments for a variety of beard lengths


  • No on-body dial for length settings
  • Dry use only (cannot rinse under water to clean)

What You Need To Know

While the cleanup may be a minor drawback for some, there is no denying the versatility and performance of this USA-made trimmer by Wahl. Able to last for several hours before needing a short recharge, its multi-functional use makes it the best cordless beard trimmer out there.

4. Best Corded Beard Trimmer: Andis Skin Close Headliner Beard Trimmer

For those who want a barber-quality trim in the comfort of your own home, this corded beard trimmer by Andis provides just that – professional level results.

Relying on a powerful electric magnetic motor that delivers an impressive 7,200 strokes per minute (SPM), this corded beard trimmer beats any other when it comes to smooth and consistent results.

With a faster SPM than a cordless rotary motor beard trimmer, your beard will look more uniform and even when looked at closely.

With a T-blade on the head of the trimmer, you can also detail the areas around your beard (such as the neck or ears) with precise lines that simply present much better.

Able to gut down to skin level – this corded beard trimmer by Andis is also great for those men who are trying to avoid pesky and painful ingrown facial hairs as it will present the appearance that you shaved with a traditional cartridge razor without actually doing so.

If there was any major downside to this trimmer, it would be the attachment combs.  With only four included, your desired beard length may be slightly restricted.

Of course, given that this is a corded device, it must be cleaned with a dry brush (rather than water) so you don’t get electrocuted.


  • Powerful electromagnetic motor
  • Delivers consistent results
  • Wide T-blade requires fewer passes and increases efficiency


  • Limited attachment combs
  • Dry use only (for safety reasons)

What You Need To Know

For those men with thick or coarse facial hair, this corded beard trimmer by Andis will cut through dense hair with ease. Thanks to the powerful motor, it delivers an easy and efficient cut every time you go to trim.

5. Best Budget Beard Trimmer: Wahl Peanut Corded Beard Trimmer

The Wahl Peanut has been a device beloved by men for years.  Not only is this device versatile as it can easily be used as a hair clipper or beard trimmer, but given the small size and equally small price, it packs quite a bunch for a trimmer.

While yes, there are inevitably some compromises that come with a much cheaper beard trimmer, the benefits outweigh them considerably.

First, let’s go over a few key features for this device:

Small Size: The biggest difference between this beard trimmer and the rest to make our list is the significantly smaller size.  Able to rest in the palm of your hand, the Wahl Peanut allows for much better control while trimming your beard.

Attachment Combs: While limited compared to some of the other beard trimmers mentioned in this guide, the Wahl Peanut comes with four attachment combs – allowing you to trim your beard to any one of the four lengths (3mm, 6mm, 9.5mm, 13mm).  There are no short settings for a stubble beard nor larger combs for a long beard – this trimmer is designed for men with a short-to-medium length beard.

Corded Power: While some may see the reliance on a cord as a disadvantage, we think just the opposite.  The corded power of this trimmer provides a much more reliable and consistent performance.  Without ever having to wait on a charge, you can get your trim done quickly and efficiently.

Price: When shopping for cheap beard trimmers, you often find low-priced products that will break down within weeks after initial use.  With the reliance on a rotary motor and carrying the Wahl reputation of quality, this trimmer should have no problem with heavy use.  To ease any concerns, this trimmer is backed by a limited one-year warranty.

Of course, at this price-point, there are some drawbacks when compared to the other beard trimmers we reviewed.  The most notable is the lack of any dial in the body to fine-tune the length settings for the trimmer.  While the attachment combs should work for most men, those that want complete control over the grooming process may be looking for more.

Furthermore, this trimmer isn’t nearly as travel-friendly as others.  The lack of a battery coupled with limited voltage use (only 110V here) prevents it from being used overseas.


  • Powerful trimmer that is affordable
  • Includes a one-year limited warranty
  • Can be used on both beard and hair


  • Not travel-friendly
  • Limited length settings

What You Need To Know

If you are looking for an affordable beard trimmer that won’t break down after a few uses, the Wahl Peanut is a great pick. Relying on a powerful motor, you can expect quick and professional-grade results at a consumer-friendly price point.

6. Philips Norelco Beard Trimmer

An update to the old 5100 that had a vacuum built into the handle that did a good (but not great) job at catching the clippings as they were cut, the latest version of the 5100 no longer includes a vacuum and focuses solely on its cutting abilities.

Here are a few noteworthy features about the 5100 that we think you will like:

20 Length Settings: Able to go all the way down to 0.4mm and up to 10mm, it provides a wide range of cutting lengths that can work for just about any beard style (with an exception only given to really long beards).   The cutting length is set by a simple mechanical turn wheel.

Strong Battery Performance: Relying on a lithium-ion battery, this trimmer provides a 70-minute run time on just a 1-hour charge.

Fully Waterproof: Whether you want to make cleanup a bit easier or simply do your beard trimming in the shower, the fully waterproof design of this trimmer gives you much greater versatility.

Hair Trimming Combs Included: With the addition of two attachment combs, you can use this trimmer to clean up the edges on you rhair. While it doesn’t have a taper lever like a traditional hair clipper, it can work in a pinch thanks to the small cutting increments provided by the zoom wheel.

Warranty: Given that it is sold by a major brand – we were happy to see that this trimmer comes with a generous 2-year warranty (extended to 5 years with product registration).


  • Fully waterproof for easy and convenient cleanup
  • Wide array of length settings


  • May miss the expectations of some men
  • It’s pricey

What You Need To Know

If you want to try a new beard trimmer that can dial into your preferred cutting length, then this model by Phillips Norelco is one of the best options out there. It displays many of the key features that men often look for in a quality beard trimmer.

7. Best Professional (Barber) Beard Trimmer: Wahl Beret Beard Trimmer

Should you be a professional barber and are looking for a beard trimmer to use on clients, then the Wahl Beret line of trimmers should be considered.

An expert balance of performance, price, and comfort, this beard trimmer delivers both reliable and predictable results.

Able to be used in either cordless or corded, the Wahl Beret offers a slightly longer body with an ergonomic grip that provides for better control to deliver great results for your clients.

Relying on a lithium-ion battery, the Wahl Beret should be able to run consecutively for two hours – which should be enough power to get you through a busy day.

But it’s the little things that really set this trimmer apart from many that make their way into barbershops – with the most notable offering being the cradle and that it can be used to hold not only the trimmer but also the cleaning brush and blade oil, too.

Furthermore, Wahl offers replacement blades for this model (2111 Snap-On).  You can read more about this blade here.

Wahl relies on carbon steel blades for the Beret – which are a bit sharper and stronger than traditional stainless steel (source).  While corrosion can be a concern for carbon steel in naturally humid environments (i.e. home bathrooms), in an airy barbershop setting, you shouldn’t run into any problem.  Should the cutting blade get wet, you can simply wipe dry with a hand-towel.

While this trimmer doesn’t come with a mechanical dial to fine-tune length settings, the included cutting guides range from 1/8” to 1/2″ – giving you plenty of room to work with.


  • Professional grade beard trimmer
  • 2-hour continuous run time
  • Cradle offers organization

How to Use a Beard Trimmer

In order to get the best results when using your new beard trimmer, we wanted to share with you four tips that we have found useful in our experiences, or those that have been shared by other men during the research of this guide:

1. Dry Beard Works Best

When using a beard trimmer, we found that cutting through dry facial hair is not only quicker but generally delivers much better results.

This is primarily due to the fact that when cutting through a dry beard, all the hairs will be able to easily stand on end and make it much easier for the blade to slice through.  When trimming a wet beard, the hairs will easily clog the trimmer.

2. Comb Beard Downwards

Before trimming, comb your beard in a downwards or uniform direction.  This will make for a consistent length that will provide uniform results as the beard trimmer makes its way through the hair.

Some beard trimmers may provide a detailing comb for this step; if your beard trimmer didn’t include one, a simple beard comb should suffice.

3. Cut from Long to Short

If you are unsure of what length you want for your beard, it’s important that you cut it in stages.  You don’t need to cut the entire beard down all at once.

There are a few ways that you can approach this.

Cut at Once: Simply adjust the settings on your beard trimmer after making a few passes to see how the results look.  If everything looks good, then you can simply trim the rest of your beard to that level.

Cut Over a Few Days: If you have a much longer beard and aren’t ready to cut significant length off of it quite yet, try trimming it over a few days.  This way you can get comfortable with a few different lengths without having any regrets.  Plus, if you take too much off, you only will need to wait a week or two in order to get back to the length you wanted.

4. Vary Length Settings for Different Areas

When trimming your beard, you don’t need to cut it all at only one length; instead, you can switch up lengths for different areas.

Many men like to keep their cheeks at a moderate length, chin at a longer length, and then keep it a bit shorter on the neck area to relieve any discomfort or itchiness.

We recommend that you take a minute to look at some beard pics either online or some relevant hashtags on Instagram to get some beard length ideas or approaches.

Beard Trimmer FAQs

Can a beard trimmer trim hair?

Most beard trimmers should not be used to cut hair.  The reason is that beard trimmers often rely on a lower-powered motor that will make the hair on the top of your head look choppy.  Secondly, beard trimmers often have much narrower heads designed to navigate the tight contours of your face.

The only exception is if you have a corded barber grade beard trimmer.  These often rely on electromagnetic motors that have a significantly higher stroke per minute rate.

Can a beard trimmer be packed in your carry-on luggage?

According to the TSA, beard trimmers and electric razors can be packed in carry-on or hand luggage in the USA (source).

Can you use a beard trimmer to trim body hair?

Yes, many beard trimmers can be used on other parts of your body including your chest, groin, armpits, or legs.  However, unlike body groomers, beard trimmers have narrower heads which may require several more passes with the device of the area that is being groomed.  Should you decide to use your beard trimmer as a body groomer, you will want to make sure that you use a body groomer attachment comb as they have rounded tips that will reduce the chance of you accidentally poking yourself in sensitive areas.

What beard trimmers do barbers use?

Most barbershops use corded beard trimmers that have much stronger motors (electromagnetic motors) than standard consumer-grade beard trimmers.

Should you be considering a barbershop beard trimmer, it’s worth mentioning that many convenience features may be missing – such as mechanical dials to adjust length settings, lack of any water resistance or waterproofing, and the inability to be used for other purposes (body grooming, ear or nose hair trimming, etc.)

Beard Trimmer vs. Hair Trimmer vs. Electric Shaver

During the course of our research of beard trimmers, we found many men get confused on some of the primary differences between this product and other common grooming tools, including hair trimmers and electric shavers.  Therefore, we wanted to take a quick moment to depict a few of their key differences.

Beard Trimmer

As you saw in our reviews, beard trimmers can come in many different varieties.  From vacuum handles to powerful corded devices – the options are nearly limitless.

When looking at a beard trimmer compared to say a hair trimmer or electric shaver, the most notable will be the head width and length settings.

Beard trimmers are much narrower than hair trimmers and slightly more when compared to electric shavers (specifically foil-based electric shavers).  This is by design as beard trimmers are made to cut the hair around the tight contours of your face (particularly along the mustache area and jawline).

Unlike hair trimmers that have restrictive length settings (based on attachment comb size), nearly all beard trimmers rely on either a mechanical or digital dial to set the length.  Able to be incremented in .5mm steps, beard trimmers are very easy to set a length to compared to a hair trimmer.

Hair Trimmer

Hair trimmers are often much more powerful devices when compared to beard trimmers.  This is because hair trimmers must cut through thick and dense patches of hair effortlessly.  If unable to perform this fundamental task, hair trimmers will pull or break the hair – which, of course, is quite painful.

In addition to the different growth patterns for the hair on top of your head versus facial hair – hair trimmers also need to cover a much wider area (comparatively speaking).  Therefore, they rely on a much wider trimmer head to improve the efficiency of the barber.

Unlike some beard trimmers, hair trimmers are designed for dry use only and never can be taken into a shower or wet environment like a beard trimmer – which restricts their overall use.

Electric Shaver

Electric shavers are significantly different from beard trimmers in many ways with the most obvious being the cutting length setting (or lack thereof).

Unlike beard trimmers that can cut at a range of lengths, electric shavers only cut at one skin-level length.

Coming in either a foil or rotary head, the way that electric shavers cut hair is also fundamentally different.

The most common shared attribute between both of these devices will be their power source (often cordless lithium-ion batteries) and their ability to be easily cleaned by rinsing under water.

It’s important to note that neither device is a substitute for one another.  Instead, a beard trimmer is a substitute for shears whereas an electric shaver is a substitute for a standard cartridge or safety razor.

Our Criteria for Choosing the Best Beard Trimmer

Sifting through all the beard trimmers available on the market today was tough.  However, once we sorted out some of the key features to consider (i.e. cord or cordless, travel lock, ease of use, length settings, etc.) we were able to narrow our list down to only a select few.

We found it best to recommend these beard trimmers based on their intended category instead of listing them out haphazardly like many other online publications.

Therefore, after all the time spent researching, we are confident with our awards for the best beard trimmers of 2021 – and we think you will be happy with them, too!
