Just bought a new iPad 3 (Love IT!) and I have been using an HP TouchPad. I was wondering if I can use the TouchPad's usb power adapter (output 5.3 V - 2.0 A) to charge my iPad. I know the iPad's power adapter is 5.1/2.1. Hate to have to spend more money for an Apple adapter if the HP will work... Thanks for any replies!
