I was looking for a little solar charger EFFECTIVE without batteries incorporated, for a reduced price, with output 2 Amps ..... I found my happiness: even on cloudy days, can I top (very) low speed my devices with USB connection, be it my phone, my mp3 and mp4 players, my nomadic pregnant, my tablet, etc., operate solar my radio (with an adapter). Without sun, so do not expect a very high intensity, but a beautiful day of spring / summer will provide a much valuable energy when it has no power outlet handy. Can be used just as well hung on my hiking bag (carabiners included). Compact size, effectiveness, two USB outputs, hanging system supplied neat finish. A must for the price (promotion) I recommend without restriction.
