It is how much charge the cell holds, and three products here publish it: a nose trimmer at 600 mAh and two lighted mirrors at 2000 and 5000.
Milliamp-hours describe how much charge a cell holds. Higher generally means longer between charges, all else being equal.
Almost nothing in this category publishes it. Shavers, clippers and trimmers publish runtimes instead, which is the more useful figure because it already accounts for how much current the tool draws.
Where mAh does appear, it is usually because the product has no runtime in the usual sense: the Auxmir mirror at 2000 mAh, stated at up to two weeks per charge, and the FUNTOUCH at 5000 mAh.
The exception is the one worth looking at. The Jeetif nose trimmer at $17 publishes 600 mAh and a two-hour charge together, and puts a battery percentage on the handle — the only product on this site that gives you the capacity, the time to fill it and a live reading of what is left. That combination is what the figure is for.
If you are comparing two tools and one publishes mAh and the other runtime, they are not comparable figures.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
