Ill let you know Yippy. They came 1/2 charged and im waiting till the monsters eyes turn green to tell me they're charged. Then Ill use the handy "play time" message on the message board to work out how long they last! But really, maybe every week or so Ill chuck the batteries in to charge over night and thats it.
And yeh, 2 chargers for each wiimote, and 2 usb slots to plug into.
