Small battery with lots of power

The capacity of 6400mAh enough second most phones or three complete charge. That's enough for a long car or train, when you're playing with the cell phone, or a weekend, if you use it normally.

I like the design very much on the silver surface you can see fingerprints, the connections are useful all placed on one side, and blue LEDs indicate the charge level. The long supplied cable is about 30 cm long and good if you want to use the Smartphone during charging, the short cable is good if you want to transport smartphone and Power Bank.

The instructions are easy to understand and explain the use of:
To charge the battery pack, you simply connect to a charger with micro USB and wait until the LEDs indicate that the power bank is full. One can virtually any charger take it.

There are two ports for charging smartphones, tablets or similar There are 1 or 2.1 amps charging current. The Power Bank can charge two devices at once. A smartphone with a battery of 3000mAh so need about 1.5 hours of charging.

The Power Bank fits well in the hand or in the pocket, the weight does not fall in the big backpack on.
I'm very satisfied.
