An empty iPad Air, an empty Nexus 7 and an empty Xperia Z2 makes it without batting an eyelid going again fully. Next I have not tested it without recharging.
Schick processed and robust. An input and two outputs. Here, however, caution should be exercised: An output is 1A, the other 2A (clearly labeled). Some devices (an example is my Xperia Z2 called) are not interested in a charge from the 1A output.
The lamp has a nice gimmick. Used I have not got it, however, so I can not really say anything to.
Once recharging takes about 7 hours. This is relatively long, but considering the power for me to understand. Good thing!
