I was looking for a powerful battery in the smallest possible design, because I do not have much space in your suitcase on business trips. This battery has 5500mAh, invites to 1A per hour. The battery is just 9.5 cm long, 3 cm wide and about 3 cm high and not even weighs 200 grams! Small, compact, lightweight, yet sufficiently juice. The Galaxy S2 combines well 2x load that can be loaded ipad to 55%. On the battery button is mounted, which can light up the Powertube. Four different colors indicate the state of charge. Pressing the button longer, a small LED that can be used as Taschenklampe lights - no idea who needs something in the battery. My conclusion: more powerful battery in compact housing for all those who travel a lot.
