Initially very good

The Cover Case Charger came - as with Amazon Orders usual - very fast with me on.
Because I've seen it already with friends and knew how everything works, I unpacked it and charged. But after a few hours (without use) the battery had been discharged something again. Are after a day, almost 25% power were consumed.
When I was on vacation and my cell phone (iPhone 5s) was almost empty, the device has given up the ghost completely. Nothing was more, which is very annoying, especially on holiday
After consultation with the seller, I have the device returned and also circumvent get my money back.

+ Charger and protective case in one
+ Easy handling
+ Invite with an iPhone charger (additional charging cables are not needed)
+ 4 LED indicators show the current charge status of the battery
+ Double battery time there with you (if the device is working ;-))

+/- Mobile recognizes that it is not an original charge cable is a warning out (work at the end but then)
+/- The phone becomes thicker and heavier! But that should be clear, since one also has an extra battery case. And there is - I personally find - perfectly fine!

- Support back flap is able to benefit very difficult
- Normal headphones can not be connected as an extension is needed (yes then you must also always there)
- The accessibility of the volume buttons will be significantly more difficult

Conclusion: good charger (I see it yes friends, where it works very well), as long as it really works !!!
In an emergency you can get help offered by the Support rapid (1-2 business days).
So I'm going to try again, and buy it to me!
