Although I was aware that this is the weakest variant in this embodiment, however, I was still disappointed that one a Sony Xperia Z2 (3200mAh battery) gets just loaded by approximately 80% (the V7 battery was full)
These "fast charges" advertise other producers with smaller and weaker battery, which is why I came out with 4400mAh of a full charge.
Otherwise, the device makes like a good idea, both optics and the LED flashlight.
However, you should (if you have a smartphone with a slightly better battery has) prefer to 6600 variant grip as far as that of the Power in my opinion is not reached.
