friend told me about these wireless charging devices...wonder if i can put my vk batteries on it and charge them. not that it is all that cost effective, but i like electronic gadgets, would be nice to just set the batteris, my ps3 controllers, cell phone, rechargables for rock band drum kit. everything all at once. any guesses anybody? dont know if the batteris have any kind of activation swith in the when they get screwed/pushed onto a charger.
