The Wii remotes are designed for two AA batteries, these are a "brick" that fits in the same space and has some other parts to them. Obviously including the inductive pickup, also some strong magnets that help position the controller on the mat. Not sure if the magnet is involved in either the inductive charge loop or the controller sensing. I haven't studied it much, but the wife has bought several of the "cheapie" cradle chargers and they've all been absolute trash. Batteries that wont hold a charge for ten minutes and useless contacts that won't actually make contact. I finally bought this set for her for Christmas this year. Haven't had an single issue with them at all. -Denny On Mon, Feb 20, 2012 at 1:43 PM, YES NOPE9 wrote: > Am I correct that for $30 I get a "charger pad" and two rechargeable > battery packs..... ? > Would the battery pack power anything of the correct voltage ?
