What is the difference between battery and electric powered vibrators? 

Generally, battery powered vibrators tend to be less powerful than electric powered vibrators. Electric powered vibrators tend to be designed with stronger motors which use more power, which means you don’t have to worry about electricity running out like batteries do.

If your electric vibrator is plugged into the wall during use, generally it can’t be used in or near water at the same time. And remember, electric vibrators can become warm reasonably quickly with the 240V running through them. So when using something powerful like the Medisil Magic Touch, we'd recommend you use it for 15-20min intervals only. That way it has a chance to cool down.
