The short answer
Buy the Wahl Aqua Blade. 180 minutes of published runtime from a 60-minute charge, a 0.2 to 25 mm cutting range, fully waterproof, and a five-year warranty with a lifetime blade warranty behind it. If you keep a specific stubble length rather than a beard, the Panasonic ER-GB80 has 39 published settings from 0.5 mm and is the more precise tool.

The four numbers, and why not the fifth
Trimmer marketing competes on attachment count, because a box with twenty-three pieces looks better on a shelf than a box with three. Almost none of that matters. What decides whether you like a trimmer is four published figures:
- Runtime. The spread here is enormous and nobody discusses it. The Wahl publishes 180 minutes; the Braun publishes 45. At a three-minute trim twice a week that is the difference between charging four times a year and charging monthly.
- Charge time, and specifically quick charge. More useful in practice than total runtime. Wahl publishes three minutes of running from a one-minute charge, which means a flat battery is never a reason to skip it.
- Cutting range, as a published minimum and maximum. If you keep stubble the minimum is what you care about and the gap between 0.2 and 0.5 mm is visible on a face. If you keep a full beard the maximum decides whether you can trim it at all.
- Whether you can rinse it. A trimmer you can hold under a tap gets cleaned. One you have to brush out does not, and a clogged blade pulls.
The fifth number - attachment count - is the one every box leads with, and it correlates with nothing.
Why the Wahl is the pick
It publishes the best figures in three of the four categories and is the only trimmer here that publishes a warranty. 180 minutes of runtime from a 60-minute charge, 0.2 to 25 mm of cutting range - the widest in this ledger - fully waterproof and rinseable, and a five-year warranty with a lifetime blade warranty behind it.
The cost is sixteen guide combs, which is a drawer's worth of plastic, and a confusing model family: the 9899 designation covers several variants that differ in what is in the box. Check the listing rather than the model number.
If you keep one specific length
Buy the Panasonic. 39 published settings from 0.5 to 20 mm across three comb attachments is the finest increment set here by a distance, and 45-degree stainless blades that Panasonic publishes rather than describes. The point of that many settings is not choice, it is repeatability: a length you like becomes a number you can write down and return to.
Its drawback is a 50-minute runtime, the shortest here, and no foil shaver in the box - so it trims and it does not take you to bare skin. If that matters, the stubble roundup is the more specific page.
If you want to trim and shave with one head
The Braun XT5 uses a single 4D blade that trims with a guard and shaves without one, so going from a trimmed beard to clean edges needs no tool change. Braun also publishes that the blade stays sharp for up to six months, which is a disclosure almost nobody else in this category offers and is worth crediting.
The trade is real: a hybrid head does not shave as closely as a dedicated foil shaver, and 45 minutes is the second-shortest runtime here. If clean-shaven is where you actually end up, the shaver roundup is the right page and the OneBlade is the closest thing to a genuine hybrid.
On do-everything kits
The Philips Multigroom 7000 is the named skip on this page and it is not a bad product. It publishes the longest runtime in the group at five hours, it has a five-minute quick charge, and its twenty-three pieces genuinely cover beard, head, body, nose and ears with no blade oil required.
The reason it is the skip is that a tool designed to do five jobs is rarely the best tool at any one of them, and this page is about the first job. The full review makes the case for it properly, which is a genuine one if what you want is one device rather than the best beard trimmer.
Every pick, with the working
Each entry shows the published specifications, the axis scores they produce and what you give up. The order is the computed order, not a commercial one, and the arithmetic is open underneath every score.
Our pickCoarse hair and long gaps between charges
Wahl Aqua Blade
180 minutes of runtime from a 60-minute charge, a published 0.2 to 25 mm cutting range, 16 guide combs, fully waterproof, and a five-year warranty with a lifetime blade warranty behind it. On coarse or dense hair the extra motor headroom and the wider guard range are what you notice.

The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- 180 minutes of published runtime — by a distance the longest here — and 3 minutes from a 1-minute charge
- 0.2 to 25 mm published cutting range, the widest in this ledger
- Fully waterproof and rinseable
- 5-year warranty plus a lifetime blade warranty, published by Wahl
Flaws
- 16 guide combs is a drawer's worth of plastic
- Model numbering across the 9899 family is confusing; variants differ in what is in the box
The working behind the 7.9
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- 180 minutes of published runtime and a 1-minute quick charge mean the battery never enters the decision (++), waterproof (+), widest published length range here (+), 16 combs to store (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 10.0
- 7 of 7 specifications a buyer would expect are published: runtimeMin, chargeMin, minLengthMm, maxLengthMm, settings, waterproof, warrantyLabel. 7 / 7 x 10 = 10.0.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Wahl Aqua Blade published specifications.
2Precise, repeatable stubble
Panasonic ER-GB80
39 length settings from 0.5 to 20 mm across three comb attachments, 45-degree stainless blades, 50 minutes of runtime from a one-hour charge, and it is washable. If you keep a specific stubble length rather than a beard, this is the trimmer that lets you find the exact number and return to it.

What it gets right
- 39 published length settings from 0.5 mm to 20 mm — the finest increments here
- 45-degree stainless blades, published by Panasonic
- Washable, and usable corded when the battery is flat
- 50 minutes of runtime from a 1-hour charge
Flaws
- 50 minutes is the shortest runtime of the trimmers here
- 39 settings is a lot of dial to turn if you only ever use one
- No foil shaver in the box, so it will not take you to bare skin

- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.

3One tool for the whole head
Philips Norelco Multigroom 7000
Skip this one. Not because it is bad - the 5-hour published runtime is the best in the group and the quick charge is genuinely useful. But 23 pieces is 23 things to store, and a tool that does head, body, nose and ears is rarely the best tool at trimming a beard. Buy it if you want one device for everything, not if you want the best beard trimmer.
Five hours of runtime from a one-hour charge, DualCut blades, and a 23-piece kit that covers beard, head, body, nose and ears. If you want one device rather than four, this is it. The five-minute quick charge is the feature you will actually use.

What it gets right
- Published 5-hour runtime from a 1-hour charge, and a 5-minute quick charge for one trim
- 23 pieces including a foil shaver, detail trimmer and nose-and-ear trimmer
- 3-7 mm adjustable comb plus dedicated beard, stubble, hair and body guards
- No blade oil required, per Philips
Flaws
- 23 pieces is 23 things to store and lose
- Philips does not publish a full length-setting list for every guard in one place
- A do-everything tool is rarely the best tool at any one of those things
The working behind the 6.3
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.0
- Published 5-hour runtime removes charging from the daily decision entirely (++), quick charge (+), but a 23-piece kit is a lot of choices to present to somebody who wanted a beard trimmed (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 5.7
- 4 of 7 specifications a buyer would expect are published: runtimeMin, chargeMin, minLengthMm, maxLengthMm. Not published: settings, waterproof, warrantyLabel. 4 / 7 x 10 = 5.7.

4Trimming and shaving in one head
Braun Series XT5
A hybrid: one 4D blade head that both trims with a guard and shaves without one, 45 minutes of cordless runtime, fully waterproof, and Braun publishes that the blade stays sharp for up to six months. The point is going from a trimmed beard to clean edges without changing tools.
- Runtime

- Every 6 months
- Waterproof

- Warranty
- Not published
- Assumed service life
- 1,300 uses
The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- One head does both trimming and shaving, so there is nothing to swap mid-shave
- Published 45-minute cordless runtime and 100% waterproof body
- Braun publishes a 6-month blade sharpness figure, which most makers do not
- Rubberized non-slip handle — a small thing that matters in a wet hand
Flaws
- A hybrid head shaves less closely than a dedicated foil shaver
- 45 minutes is short next to the Wahl's 180
- Replacement blades are proprietary to Braun
The working behind the 5.8
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.5
- One head for trimming and shaving removes a tool change from the routine (+), waterproof (+), published 6-month blade life is a rare disclosure (+), 45 minutes is the second-shortest runtime here (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 2.9
- 2 of 7 specifications a buyer would expect are published: runtimeMin, waterproof. Not published: chargeMin, minLengthMm, maxLengthMm, settings, warrantyLabel. 2 / 7 x 10 = 2.9.

Questions people actually ask
What length should I set a beard trimmer to?
Start two settings longer than you think you want and work down. You can always take more off; you cannot put it back. Heavy stubble is around 3 to 5 mm on most trimmers and a short full beard around 6 to 10 mm. The guards guide has the mapping.
How often should I replace trimmer blades?
Most makers do not publish an interval, which is exactly what our disclosure axis marks down. Braun is the exception here: it publishes that the XT5's blade stays sharp for up to six months. In the absence of a figure, the practical signal is the same as a razor blade - it starts pulling rather than cutting.
Do I need a waterproof trimmer?
You need one you can rinse, which is not quite the same thing. Beard hair and skin oil clog a blade, and a trimmer you can hold under a tap gets cleaned while a trimmer you have to brush out does not. Three of the four here are published as washable or fully waterproof.
Is a corded trimmer better than cordless?
No, and the question has mostly stopped mattering. What matters is the quick charge: a trimmer that gives you a few minutes from a one-minute charge never stops you trimming, whatever its total runtime. Both the Wahl and the Philips publish one.
