The perfect alternative to a second battery

This Power Bank is the perfect alternative to a second battery, because it is still mobile, the battery does not need to fumble for the phone (on some phones, too impossible) and has supplied his smartphone for a long time.
With this capacity I can charge my phone loose three times complete, the non-plus-ultra of the way, to work, on vacation, etc.

I invite to the Power Bank overnight and then it is ready for use, even with integrated flashlight and battery capacity indicator of the Power Bank itself.

For the money simply unbeatable, processed very valuable and small, so they can take anywhere.
