Electric vibrators are the oldest kind of vibrator out there. These are the kind that you either have to plug into a wall or that use a rechargeable battery. Generally speaking, they pack more punch than the battery operated vibes, have a longer lifespan, and can be used for sensual massage as well as sexual use. The main disadvantage to most electric vibes is that you have to be close enough to a power outlet to plug them in while you play. There are two main kinds the wand vibrator and the coil vibrator. The wand vibrators are epitomized by the Hitachi Wand. The coil vibrators are great since they don't make much noise and provide a more buzzy and less thumpy vibration.
