Sorry if this is a really numpty question, but I've just bought a PS3 (never had one before) and a second Dual Shock 3 controller to go with it. I han't realised that the controllers were wireless (which is good!), but the second controller does not include a USB cable to charge it (it just says to use the one that came with the PS3).
So my question is - is this normal ie. do most people just use one cable and alternate between controllers to charge them? Or do you buy another cable? Or is there a better way to keep them both charged?
