Poor layout has the charge cable under controller so it sits on the usb jack. Subsequently after two weeks and two charges one of the units has stopped charging and is ratting so I suspect the usb jack has broken inside the battery. Save up and buy the microsoft one.

To charge these battery packs the plug is inserted into the back of the controller, not the top, the down side to this is the very first time I dropped the controller (which happens from time to time) the plug in the battery pack broke, this was from sitting position onto carpet! Dont bother with these just use rechargeables.

Got mine with the xbox, worked fine for about a week. Micro usb port came out with the plug and now won't charge (obviously). Second battery is on the blink now too.
