VGR V-071 Cordless Hair and Beard Trimmer - 120 Minutes, USB-C

Two hours of runtime is the specification that matters on a trimmer, because the failure mode of a cheap one is dying halfway through a haircut. The V-071 runs 120 minutes off a 600 mAh cell and refills in about an hour and a half over USB-C.

Stainless-steel blades cut down to bare skin and up to roughly 3 mm with the guides fitted, which covers a beard line, a neck edge and a fade. Cordless throughout — no cable dragging across the mirror while you are trying to hold an angle.
