By portable I mean something with its own battery and yes it would be good if it has 2 usb outs.
I have a 6600maH battery with 2 USB charging ports one 1A and one 2.1A (this is the important spec for iPad charging). I got it from DealExtreme (import from HK) This sort of thing is now avail at Dick Smith ..I think Belkin brand ..but dearer.
So from what I understand the Ipad needs a 2.1A charger right ?
So , please advise if you know of good portable (with battery) chargers for Ipad !!
Thanks
