EasyAcc 15000mAh Brilliant Ultra Compact Dual USB Power Bank

I received the package after 2 days. The packaging was perfectly tailored to the size of the contents.
The carton is spartan, but the content is well protected and finds good place. The content of the accompanying booklet is short, but as far as you do not understand on the device.

There are two USB cable included. A 20cm and 60cm a cable. The 20cm cable extends from just so that you can plug in it and put the phone on top of the Power Bank.

When unpacking the device does not have this again union plastic odors.
The feel is comfortable and it fits comfortably in your hand. It is about as big as my phone and about twice as thick. The weight is noticeable, but completely under (there are now just about 7 batteries into each other).

At first I thought: Oh no charger ...
But there is a common micro usb port, so I can just use the phone charger cable with me.

The pleasant was, on delivery, the device was already fully charged ie one can also be ordered at short notice and take it.

There are two front connectors for charging. As I mentioned above only my Galaxy S4 boot order, I use only the 2.1A port.

There is also an indication how full of the Power Bank battery. There are in addition to the USB slots a small (in my case) orange button as you can see in Figure 4 on the left.
On top of the device are 4 LED lights attached, indicating the current level of the device. Each lamp stands for approximately 25% load volume.

In a first test on the 2.1A port I have about 40min required for 45% battery level (no simultaneous use of the phone).

It is described that can use the telephone more during charging. I think this is the weight of the power bank too big and it is too thick, so that the phone is still well in hand. Should you wish, however, the included USB cable 20cm is probably a good choice, because then you do not have too big cable clutter around them.

After the first test, therefore, the device has me convinced. So far I could not find any negative points.
Therefore, there is for me at this point 5/5 stars.
