Introducing Wahl’s Slate Stainless Steel Lithium-Ion Trimmer – your beard’s new best friend.

Wahl USA Stainless Steel Lithium Ion 2.0+ Slate Beard Trimmer for Men - Electric Shaver, Nose Ear Trimmer, Rechargeable All in One Men's Grooming Kit - Model 9864

Wahl’s Slate Stainless Steel Lithium-Ion powered beard trimmer has quickly become a favorite among men who take their beard grooming seriously. Its popularity is due to its sleek design, impressive battery life, and the awesome versatility it offers with its ample attachments.

So, why does grooming and maintaining a well-groomed beard matter, you ask? 

Simple – a well-groomed beard is not just about aesthetics. It’s about making a statement

It says, “I care about my appearance. I take pride in my personal style.” 

And most importantly, it’s about feeling good in your own skin. So, let’s dive into the hairy details of the Wahl Beard Trimmer and see how it can help keep your whiskers looking wonderful.

Features of the Wahl Beard Trimmer

Alright, let’s unravel the mysteries of this beast of a tool. The Wahl Beard Trimmer is packed with features that make it a heavyweight champion in the beard grooming world.

Self-Sharpening Blades

First off, the trimmer is armed with self-sharpening stainless steel blades. This blade is the Einstein of the grooming world, continuously honing itself to remain razor-sharp until the end of the trimmer head’s life. 

Forget the hassle of oiling and maintaining sharpness – this blade is always ready for action. 

The superb sharpness ensures a fast, flawless trim every time. No pulling, no tugging, just smooth operation.

Lithium-Ion 2.0 Battery

Wahl, in their infinite wisdom, have packed this trimmer with a powerful Lithium-ion v2.0 battery. This isn’t your everyday, run-of-the-mill battery. This is a battery that offers 4-6 hours of continuous cordless trimming and shaving with just one hour of full charge. 

A solitary charge can keep this beast roaring for nearly a month. This cordless marvel of engineering can keep your whiskers refined and regal even if you’re halfway up the Andes, wrestling with llamas and searching for ancient Incan gold. 

If you somehow manage to run out of juice, fear not, because the Wahl Beard Trimmer offers a quick charge feature that gives you a full trimming or shaving session with just a one-minute charge. Talk about a fast comeback.


When you’re on a mission to groom, length is the name of the game, and the Wahl trimmer comes fully prepared. 

It brings a full set of twelve trimmer guards to the table, ranging from 1/16″ (1.5mm) to 1/2″ (13mm), with a 10-position adjustable guide. This means no matter your beard length preference, from the suave stubble to the majestic full-length beard, this trimmer has got your back.

Wahl products aren’t just about the beard – they’re about full grooming supremacy. The Wahl trimmer comes with four attachment heads – the T-blade, dual shaver, ear and nose trimmer, and precision blade. 

Each of these attachment heads has its own unique role in your grooming journey. The T-blade is your go-to for beard grooming and touch-up trims. The foil shaver head gives you a close shave, perfect for those sleek, clean-shaven days. 

The ear and nose trimmer takes care of those tricky, hard-to-reach areas, and the precision detail trimmer helps you achieve fine detail trimming. A truly all-in-one grooming kit indeed.

With this diverse arsenal of accessories, the Wahl trimmer stands ready to help you maintain a well-groomed beard, no matter your style.

Best Features

Now let’s talk about the features that make this trimmer the ultimate travel buddy. To kick things off, the trimmer comes with a travel bag that makes you feel like James Bond (just, with a beard), designed to safely carry the trimmer and all its top-secret attachments.

Included is a multi-voltage charging adapter and plug supporting both 110v and 220v, allowing you to recharge the device from anywhere in the world. Whether you’re in the urban jungle of New York or a cabin in the woods, this trimmer is always ready for action.

Next, we have the LED indicator, a nifty feature that lets you know when the device is charging and when it’s fully charged – a feature that’s really overlooked with a lot of trimmers out there. 

And finally, let’s talk about the build quality. The body is manufactured with both stainless steel and high-grade plastic, giving it a sturdy and durable build. The Wahl trimmer has a good center of gravity and weight. If you’ve ever dueled with a top-heavy trimmer, you’ll know this is an essential quality of any beard trimmer.

And although it’s not waterproof, the build quality of the attachments is solid, allowing for an excellent trimming experience and satisfying click upon attachment.  

5 benefits of using the Wahl Beard Trimmer

Let’s dive into the meaty benefits of using the Wahl Beard Trimmer, the secret weapon in your grooming arsenal. 

1. Grooming in the Comfort of Your Home

First up, we have the sheer convenience of trimming at home. Imagine, no more awkward small talk with your barber, no more waiting for your turn in a room full of impatient men. 

With Wahl products at your disposal, you can maintain your beard from the comfort of your home, while listening to your favorite tunes or catching up on the latest episode of your favorite show.

2. Say Goodbye to Barbershop Bills

Let’s talk about the green – and no, we’re not talking about eco-friendliness (although Wahl is all for that too). We’re talking about the moolah, the dough, the cold hard cash you’ll save by investing in a Wahl trimmer. 

Compared to the repetitive costs of salon visits, owning a Wahl trimmer is like finding a pot of gold at the end of a rainbow. It’s a one-time investment that keeps on giving.

3. Custom Beard Styles at Your Fingertips

The Wahl trimmer is like a magic wand that allows you to customize your beard style to match your mood or the occasion. 

Want to sport a dashing goatee for your date night? No problem. 

Fancy a full lumberjack beard for your weekend hike? 

Wahl’s got you covered. With the different length settings available, you can groom your beard exactly how you want it. 

4. Precision Beard Trimming

If a neat and clean look is what you’re after, then we believe the Wahl trimmer is a good choice. 

Its self-sharpening stainless steel blades glide through your beard like a hot knife through butter, ensuring a precise trim every time. Say goodbye to uneven lengths and stray hairs. With the Wahl trimmer, every day is a good beard day!

Trimmer Showdown – Comparing Wahl to Other Top Contenders

Enter the grooming game with the finest trimmers in the market. Let’s dive into a comparison between our main contender, the Wahl Beard Trimmer, and three other power players in the field. 

The Remington Beard Boss – The Crafty Competitor

Meet the Remington Beard Boss, the cordless contender vying for your attention. This trimmer is not afraid of water – it’s 100% waterproof. So, whether you’re a shower shaver or a sink-side stylist, the Beard Boss has your back. And when it comes to stamina, it’s a marathon runner with up to 180 minutes of cordless runtime. 

Need to power through a dense forest of facial hair? No problem. Turbo mode is your secret weapon. But while it’s a rugged all-rounder, it might not offer the same breadth of accessories as our main contender, the Wahl.

Wahl Peanut – The Compact Champion

Next up, we’ve got the Wahl Peanut. Don’t let the cute name fool you – this trimmer is a serious performer. 

Its compact design and lightweight make it a dream to handle, so you can style it with precision and comfort. The detachable blade is a maintenance blessing – cleaning and upkeep is a breeze. 

However, being a corded trimmer, the Peanut doesn’t offer the freedom of cordless operation that you’d get with the Wahl. Plus, it definitely can’t match the Wahl in the versatility department.

Braun Beard Trimmer 9 in 1 – The Jack of All Trades

Finally, enter the Braun Beard Trimmer 9 in 1. This is no mere trimmer – it’s a full grooming arsenal. 

Ready to tackle everything from beard hairs to ear & nose trimming, hair clipping, and even full-body manscaping, it’s a tool of many talents. 

The AutoSense technology is like having a professional barber at your fingertips, adapting to the density of your beard hair for impressive results on any hair type. Plus, it’s 100% waterproof – just like the Remington. 

But be aware, the Braun can’t quite match the Wahl’s battery life, and its range of specific trimmer guards is not as extensive.

How to Use the Wahl Beard Trimmer

So, you’ve got your Wahl beard trimmer in hand, you’re standing in front of the mirror, and you’re ready to start taming that glorious facial hair of yours. 

But where do you start? Don’t sweat it, we’ve got you covered with a step-by-step guide on how to use your trimmer to craft different beard styles, tackle the tough spots, and keep that beard looking its absolute best.

Step 1. Prep Work

Before you dive into sculpting that face mane of yours, we’ve got to do some prep work.

Freshen Up That Beard – Kick things off with a clean slate. Give your beard a nice wash with a gentle cleanser to get rid of any grime or oils that might get in the way of your grooming session. After this, make sure it’s totally dry – a damp beard will make your hair stick to your face and the trimmer.

Pick Your Length – Wahl’s got you covered with a smorgasbord of length options. Slide on the comb guide that matches the beard length you’re shooting for. 

Pro tip – Always err on the side of going too long. You can always trim it down more if you need to.

Give Your Trimmer a Once-Over – Make sure your Wahl trimmer is clean, and those blades are sharp and ready to rock. If it’s been gathering dust in your drawer for a while, it’s a good idea to give those blades a little oiling.

Step 2. Craft Your Style

Alright, now that we’re prepped, let’s get down to business – carving out your signature beard style, for all beard lengths.

Short Beard

Ah, the short neat beard – classic, manageable, and always in style.

  1. First, arm yourself with the T-blade trimmer head and the trimmer guard that matches your desired length. Remember, it’s always a good idea to start with a longer guard and work your way down. You can always trim more off, but you can’t put it back on!
  2. Now, it’s time to get down to business. Trim along the grain of your beard growth to ensure an even cut. This is also a great time to clip those rogue hairs that have a mind of their own.
  3. Last but not least, whip out the precision detail trimmer to shape your beard and mustache. This is your chance to really personalize your look and make it uniquely yours.

Medium Beard

Got a bit more length to work with? No problem, the Wahl trimmer is up to the task.

  1. Kick things off with the T-blade trimmer head, and pick the trimmer guard for your chosen length.
  2. Trim along the grain of your beard growth, starting with the longer hairs. This is where you can start to shape your beard and define that neckline. Remember, no one ever made friends with a neckbeard.
  3. To finish, use the precision detail trimmer to carve out those clean lines around your beard and mustache. Remember, it’s all about symmetry.

Long Beard

Alright, wizards, this one’s for you.

  1. For those sporting a Gandalf-length beard, grab the T-blade trimmer head and take a deep breath. Yes, you’re going to have to remove the trimmer guard and go freehand. It’s a bit nerve-wracking, we know, but you’ve got this.
  2. Trim along your beard growth, keeping an eye on the horizontal edge to make sure it’s even. Remember, symmetry is key here. Make sure to keep the same length on either side of your face.
  3. Use the precision detail trimmer to shape your beard and maintain those sharp lines. And don’t forget to comb it out first to get a true sense of its length and shape.


The stubble look – for those days when you’re feeling a bit rugged.

  1. Start off with the T-blade trimmer head, but leave the trimmer guard in the box. This one’s all you.
  2. Give your entire beard a trim, moving along your beard growth. This will give you that perfect 5 o’clock shadow look.
  3. Finally, use the precision detail trimmer to keep your stubble lines neat and well-defined. Because even a rugged look needs a bit of refinement.

Step 3. Navigating The Tricky Spots

Neckline – When it comes to the neckline, tilt your head back a smidge and look up. This tightens the skin, making it easier to trim. Remember to trim with the grain of your hair growth to avoid those pesky ingrown hairs.

Mustache – For your ‘stache, the precision detail trimmer is going to be your best mate. Trim along the grain of your hair growth and keep those lines crisp and clean.

Sideburns – For sideburns, keep that precision detail trimmer in hand. Hold the trimmer vertically, and start from the top, trimming down to your desired length.

And there you have it, gents! With these steps, you’re well on your way to taming your beard into submission with your trusty Wahl beard trimmer. 

Grooming extends beyond trimming – brushing and combing your beard are also crucial. If you’re yet to own a top-quality brush and comb, take a look at our offerings and choose your bundle.

Showing Your Trimmer Some Love

Alright, let’s get real. Your Wahl trimmer is your buddy, your partner-in-crime when it comes to grooming. It deserves some love and care, right? Well, here’s how to give it the TLC it needs to keep serving you like a champ.

Cleanliness is Next to Handsomeness

After each epic trimming session, take a moment to clean your trimmer. The best way is to brush off any hairs chilling on the trimmer head with the small brush that came with your Wahl kit. 

For a deep clean, you can pop off the trimmer head and evict any hairs that have made a home underneath. Wrap it up with a quick wipe down with a dry cloth. 

Remember, a clean trimmer is a happy trimmer!

Oil’s Well That Ends Well

Here’s a secret – your trimmer LOVES oil. A few drops on the blades, let it run a few seconds to spread the love, then wipe off any excess. Boom – your trimmer is now smooth and slick, ready for the next round.

Safe and Sound

Stash your trimmer in a dry, safe place when you’re not using it. The travel bag that came with your Wahl kit? Perfect! Your trimmer will be cozy and ready for action the next time you need it.

And there you have it! Keep your trimmer clean, oiled, and safely stored, and it’ll keep you looking sharp. It’s a win-win!
