I saw an advert for something like this yesterday where it charged electronic devices without plugging it anything in. Does anyone know anything about it, how much it'd run me, and if it's at all effective in actually charging things?

it's effective

just google it, seriously

gonna make charging my psp's and xbox controllers much less of a bitch

I think this kind of devices are here for few decades.

A electric toothbrush is placed on a soket and left there for some time>.it's charging itself>>but the soket in plugged in ofc
