The best budget beard trimmers

What the money actually buys

A trimmer is a motor, a blade set and a battery. At the bottom of the market the blade is rarely the problem - stainless or coated steel cuts beard hair perfectly well, and a cheap trimmer that is clean and oiled cuts like an expensive one.

The battery is where the money went. Cheaper cells hold less, sag under load and take far longer to fill, and the honest makers publish that. Wahl publishes NiCad on the Groomsman, which is telling you exactly what you saved. Philips used to do the same on the model the All-in-One 3000 replaced; it now publishes no cell chemistry, no runtime and no charge time for this line at all.

What this page ranks on

1. Published runtime and charge time, as a pair. Runtime alone is half a number: sixty minutes from an overnight charge is a different product from sixty minutes from one hour. A trimmer that publishes neither cannot be placed on this axis at all.
2. A published cutting range in millimeters. "Eight settings" tells you nothing about where they start or stop.
3. A published warranty. The cheapest insurance against the battery being the thing that fails.
4. Washability, in the maker's exact words. Rinseable blades and a fully washable body are not the same claim.

Published figures

The pick: Philips Multigroom 5000

Eighteen pieces, a published 2.8 hours of runtime, eleven length settings across a published 0.5 to 16 mm, fully washable, no blade oil required, and a published two-year warranty.

It is the best-documented trimmer at this price. Runtime, cutting range, washability and warranty are all published, and 2.8 hours of runtime is more use than most people get through in a month of trimming.

The honest cons. Philips does not publish a charge time for it at all, which is the one figure missing from an otherwise complete sheet. Eighteen pieces is a lot of plastic and you will use four of them. There is no foil shaver head in this kit. And the heads are proprietary, so a lost comb is a Philips order rather than a generic one.

The longest warranty: Wahl Groomsman

Eight guides spanning a published 1.5 to 13 mm, one of them a six-position adjustable guide rather than a fixed comb, behind a published three-year warranty - longer than either Philips here.

The adjustable guide is the useful part. Six positions in one comb means fewer plastic parts to lose and finer steps between lengths than a stack of fixed guards gives you.

The honest cons. The battery is NiCad, which Wahl publishes plainly - the oldest chemistry in this ledger, and the reason the trimmer sits here rather than a tier up. Wahl publishes neither a runtime nor a charge time on its own page, so two of the four figures this page ranks on are simply absent. And the bonus nose trimmer needs batteries that are not in the box, which Wahl also states.

The most kit for the least money: Philips All-in-One 3000

Thirteen tools, self-sharpening steel blades rather than coated ones, rounded blade tips that Philips publishes as gentler trimming, and a published two-year warranty on registration. For the money it is a genuine multi-tool, and a stated warranty at this price is not nothing.

The honest cons. Philips publishes no battery type, no runtime and no charge time for this line, so you cannot plan around it or compare it with anything. No cutting range in millimeters either - just "different length settings". And no water rating at all, which means nothing here tells you any part of it may be rinsed.

Making a cheap trimmer last

At this price the tool rarely dies of blade wear. It dies of neglect and of battery management, and both are avoidable.

• Brush it out after every use. Cut hair packed against the blade is what makes a trimmer pull, and pulling is what makes people conclude a cheap trimmer is a bad one. Ten seconds with the brush in the box.
• Oil the blade. A drop at each end of the blade, run it for a few seconds, wipe the excess. Wahl supplies oil with the Groomsman; Philips publishes no oiling instruction either way for the All-in-One 3000, so a drop of clipper oil is the safe default.
• Plan the charge. Where no charge time is published, assume overnight until you have timed it yourself. Older cell chemistries also dislike being stored flat, so charge it before it goes in a drawer for a month.
• Rinse only what the maker says is rinseable. Philips publishes no water rating for the All-in-One 3000 at all, so brush it out dry rather than guessing. Getting that wrong is the fastest way to kill one of these.

A cheap trimmer that is clean, oiled and charged cuts like an expensive one. The difference the money buys shows up in the battery and the warranty, not in the cut.

When to spend more instead

The Aqua Blade sits on this page as the ceiling for a reason: every figure this page ranks on is better. A published 180 minutes from a 60-minute charge, a published 0.2 to 25 mm range across sixteen guides, full waterproofing, and a five-year warranty with a lifetime blade warranty behind it.

If you trim twice a week, the warranty alone is most of the price gap, and the battery will still be working when a NiCad cell has stopped holding a useful charge. The main trimmer roundup ranks the field without a price ceiling.
