The electric shaver (often known as the dry razor, electric shaver, or just shaver) is a razor with a rotating or oscillating blade. The electric shaver usually will not require the consumption of shaving cream, soap, or water. The razor could be powered by a tiny DC motor, which is either powered by batteries or mains electricity. Many modern kinds are powered using rechargeable batteries. Alternatively, an electro-mechanical oscillator driven by an AC-energized solenoid can be utilized. Some very early mechanical shavers had no electric motor and needed to be powered by hand, for instance by pulling a cord to operate a vehicle a flywheel.
Electric razors fall into two main categories: foil or rotary-style. Users have a tendency to prefer one or the other. Many modern shavers are cordless – they are charged up with a plug charger or they are located within a cleaning and charging unit.
