Nice complement for tablet

If it is possible to charge a mobile phone, it is only if we have the USB cable that has a nozzle and the other corresponding to taking the smartphone .... and it is far from standard.
The Ipad has the advantage of having the AC charger that this cable.
Certainly more efficient to troubleshoot all solar stuff much more expensive, to troubleshoot when fully discharged his phone when you forget to turn it off by entering an underground or a forest where nothing happens several hours (it consumes more searching the network).
The price is very decent compared to what we are asked to change a laptop battery, Iphone in particular!
