The best solar panel at this price

My first solar panel, commissioned after reading the reviews (mainly on US forums).
Can not go wrong with this product, which is simply the best solar panel below 80. Charging Testing a Galaxy S4 morning a campsite in the north, clear sky, bright sunshine:
8am: 51%
11h 100%.
Wifi / 3G disabled.
Incomparable with a power source, of course, but for the solar, it's all good!

Only drawback: Heavy enough. 700g, it's embarrassing for hiking, where weight is important ... But camping, placed on a tent, is nickel.

Very versatile (USB plugs), you charge what you want or almost ...
