Now you can dock charge controllers from mains BEFORE play!!
If, like me, you have docking station to charge the controllers but hate leaving the wii on (waste of electricity, overheating wii etc) just to charge your controllers, dont want dock hooked to a laptop, need both USB ports for HDD and game peripherals (mics guitar etc) you can pick this up from PLAY.com for UK mains (from only £1.38 GBP with FREE postage and packing!!).
(There are more expensive ones with worldwide adaptors etc at maplins)
Now you can have your wiimotes charged before play and free up a valuable USB port!!
