With a charging time of about 2 days and a capacity of 2200mAh no continuous operation of current smartphones is possible with this charger, since the capacity of the mobile phone battery is greater than the capacity of the supercharger but usually by holding only one day. The benefit is therefore rather doubtful. The loader itself appears high, the silicone shell feels great and with the carbine sees the whole of as chic, but the box is a bit too thick at the back of the scarce capacity and thus quite impractical for mobile use. What ultimately led to the rating of 2 stars is still poor value for money and the poor support. On a request to the manufacturer's website, I received an answer after 8 days, it was incompetent and null helpful. The price fast and competent assistance must be granted.
