Rectangular, practical, good

When I unpacked the Power Bank and wanted to use the first time, I had my difficulties so.
After reading what meant the lights on the side, I wanted to charge the device, but it took an unusually long time. Therefore, it was only times lie.
Once again I looked into it, I could see that the cable was easily slipped out during charging and the device is therefore as long as needed. Here I must also say that the provided cable is very short and the power bank, if you are not an outlet is directly on the ground, hanging in the air, the cable can easily slide out.
After I downloaded it, I could use it well to load my phone three times. And after that it was still not empty.
My iPad I have also loaded it. However, it took a relatively long time.

I find the device totally practical if you have a long road somewhere where you have no electrical outlets. One can even his friends give battery :)
However, I must say that the device is a little hard to wear it every day in your handbag.
