Detailed operating instructions are Aufschlus about the correct use: The battery charger is plugged in and recharged using the included USB cable to a power source. The LED flashes to indicate that charging is taking place. Once the red light resistant, the process is completed and the battery is charged. After charging a blue LED light illuminates when you have removed it from the power supply. Begins the blue indicator blinking, the battery needs to be recharged, because it has reached less than 25 percent charged.
Conveniently, the small charger cable to the micro-USB port is connected to the charge of the smartphones or tablets securely to the charger, and only needs to be pulled. Then it can be with the micro-USB port on the device that you want to charge, connect. Equipped smartphone or tablet is not a micro-USB port, however, you need an adapter, which must be purchased separately. Thus, it is the case for example with Apple products.
The charger is available in several versions. I have the weakest variant (2000 mAh), therefore the capacity is not particularly large. In my experience, this variant errreicht only charging up to 50 percent on my smartphone, and up to 25 percent at the Tablet. On the go that is at least at the phone in order, but who sets great store by more power, should select a more powerful version.
All in all, a convenient charger on the go, but in this version, but a bit weak, especially for power-hungry devices. Here I recommend to choose a more powerful version!
