Several manufacturers, including Body Mate, Omron, Wahl, Panasonic,
and Conair, make rechargeable massagers. Most are of the Hitachi Magic
Wand variety. A few sex toy manufacturers also make rechargeable
vibrators, such as the Rechargeable Rabbit.
Rechargeable vibrators don't keep a charge as long as conventionally
powered vibrators. Expect to get anywhere from 3 hours to 45 minutes
of continual use. However, they are easy to recharge; usually they
come with an AC adaptor that plugs into a wall socket and recharges
the vibrator's internal battery cells. When you're through with it,
plug it into your bedside outlet, and it will be ever ready.
