Main types include foil shavers, rotary shavers, and rechargeable trimmers or multi-purpose groomers that use dedicated trimming heads.
Electric razors use a mix of power sources: replaceable AA (alkaline) batteries, rechargeable NiMH batteries, and rechargeable lithium‑ion batteries. Listings commonly describe products as battery‑powered, rechargeable, and cordless.
Many models are wet/dry capable and described as washable or waterproof. Care instructions commonly recommend rinsing under water and using a small brush for detailed cleaning.
Blades and guards are typically rinsed under water and cleaned with a small brush. Some trimmers have detachable blades and guards for easier rinsing and note that blade oil is not required.
Several models list a roughly 5‑minute quick charge that provides enough power for one shave — a short top‑up intended to deliver a full shave when needed.
