Update in mid-June 2015: had decided after the manure from above to use it as a current donor fo 1 and 2 RaspberryPi Cubieboards. Today it was so, that the 2 Cubieboards suddenly only and auschalteten itself, apparently the power supply of the matter is not grown, although it worked well for half a year.
Get it now only use them to charge the PS4 controller.
