The DOAO Electric Razor is a rotary shaver with a double-track cutter, a pop-up sideburn trimmer, a 9,000 RPM motor and a USB-rechargeable battery. It is listed at £29.99 and holds 4.4 out of 5 from 1,437 Amazon ratings, and it sits at number 10 in this guide.

Its battery figure is the one in this guide that does not change unit between fields: the Battery Average Life spec says 120 minutes, and the USB Quick Charging bullet says about 120 minutes of shaving time from a 1.5-hour full charge. The break sits inside that same bullet, which calls the 120 minutes "approximately 50 full shaves" — divide one by the other and you get 2.4 minutes per shave. The title also claims 100% waterproof, while the Wet & Dry bullet and the Special Features field both say IPX6, which is a rating for jets of water rather than for leaving the shaver submerged. Everything on this page is taken from the Amazon listing; we have not tested the shaver ourselves.
