I have the device for three weeks in use and it does the job reliably. Once it has been charged, I can upload it to my phone up to five times up to 100%. It is only to be noted that the charger is relatively large and heavy (bigger and heavier than my Iphone 4s).
The only thing I did not like that the Adapter for iPhone absolutely does not fit. Have therefore equal discarded him and simply remove the USB cable of my Iphone charger in use. Therefore, a star deduction.
