Small but nice! Plus powerful and inexpensive !!

Originally had a different brand bought with 20,000 mAh - unfortunately it was on the first day only charge to 99%, and by 4 times will discharge was then already at 95% final - no matter how long you tried it! Well, that's why I opted for a smaller capacity and another solid manufacturer. But a display with charging indicator in% should necessarily be present as its predecessor! The oxa met all my needs and is of course better to carry, not only because of the lower weight / size, but also because of the supplied stable padded bag. BDA is in German and English, the other is a multifunction adapter cable with this - with adapter and Lightning Iphone connector and microUSB. What more do you want! ? 10 000 mAh rich normally, whoever is longer outdoor, course needs 20 000 mAh or more - but also means a lot more weight.
To load my iPads or the Kindle Fire HD 8.9 my wife - sufficient capacity for either iPad or the Kindle Fire HD to one charge of about 20/30% to 100% at 2.1A output. The remaining capacity can subsequently or simultaneously even my Samsung Galaxy S3 will be charged at 1.0 A output. So, enough to be supplied on a long train journey. Almost forgot - twice pressing the power button, the LED light is activated - good for the way home in the dark, and for finding the right key to the garden door unlit. Oh, almost forgot - the display legible in which the outputs will be used, and whether the Power Bank is charged or discharged.
Just buy it from me!
