The operation is explained very simply and sufficiently intelligible. The current memory is sufficient for more than five battery charge my smartphone (Samsung Galaxy S4 mini). Just tested it I can not but you calculate (not forget to wear.) The current memory is quite warm during unloading, but this is harmless. Because the power supply for the smartphone is getting warmer and the smartphone itself also.
When power supply for a tablet (Samsung Galaxy Tab 3, 10.1) of the current memory is even warmer, but still bearable. It should be clear that the current storage should not be in the sun ;-)
On the front are in addition to the USB ports current information (1A = 2A Smartphone and Tablet) that should also be noted. Otherwise, the charging electronics in the smartphone / tablet or the current memory may burn. Best be compared to that of the smartphone / tablet supplied AC adapter.
Charging may by an up to 2.5 A strong USB power supply occur (which is not provided here). The included micro-USB cable is plugged in and turned on the side of the entrance. I almost always use the 2A PSU in my Tablets. With a 1A power supply, the charging process takes an eternity ...
As a little gimmick of the current store has a bright LED that can be activated by pressing the button twice recently / disabled. Probably looking one or the other so that anything - I have a bulb never needed.
The accessories (not visible in the pictures) is next to the USB cable (USB-A to Micro USB) a pouch / sachet in which the current memory and the cable can be accommodated.
