After fully charging the battery, I first tested at home on many small devices (mobile phone, MP3 player, camera, audio mini speakers, small portable radio, etc.). To do this, I used the port debiting a current of one ampere. Everything went well, sometimes through the two adapters in addition to the primary USB cable. The energy level remaining visible on the LEDs on the upper side, had barely fallen.
Then I took the train intentionally not my laptop recharged beforehand. As soon as he showed signs of weakness, I connected (to the astonishment of my neighbors travel; it was quite fun ...) to port two amps.
Again, success. And the battery still has strong reservations.
The two ports, each operating at a voltage of five volts, as always in USB are visibly filled the back of the device. With multiple built-in safeguards, you risk nothing to use the port of two amps in all cases (but this is of course not the smartest approach). If you connect gluttons devices on port of one ampere, the time will obviously lying, but no damage either.
Also mention that the finish of this battery is very neat and it is easy wins, and its accessories (little cumbersome) in the small bag with closure cord, also provided.
