The Powerocks Stone 3 portable power pack for iPad and Galaxy Tab solves a problem. It’s all very well having a common interface for charging but when people break the specs it becomes less useful. The iPad and Galaxy Tab charge using very high currents through a USB port that excedes the capability of the USB port you’ll find on nearly all laptops and PCs which means you generally have to carry the mains charger around with you. I found a portable power pack at IFA that supplies the correct current to allow full-speed charing on the go and it works. At least with the Galaxy Tab I tested with it.

There’s no European distributor for the Stone 3 yet so you’ll have to keep your eyes open for availability. Alternatively, wait a while because I’ve got a unit coming from Znex. The Power-Pack IP is said to do the same so i’m looking forward to testing one that’s available right now.

Here’s a video and you’ll find some images below that.
