A battery that stands out not only in shape and appearance, but is also ideally suited for its intended purpose. He is really highly recommended, so much so that I - have already ordered another - after the first tests. I have charged three times my smartphone (an older Samsung Galaxy S2 Mini) and the battery is still not exhausted (Ladestands- / capacity indicator: still 2 of 4 light points).. This is first class. To underline the very compact design compared to Power Banks comparable performance (Dimensions: L 9.5 x W 4.1 x D 2.2 cm). Caution: The enclosed charging cable does not fit for iPhone / iPad, because the do not have a micro-USB port. For an extra charge cable must be ordered (for iPhone 5 / iPad 4 eg iProtect 2x USB charging cable u. Data cable).
