If you're only counting on this to charge your phone or other device using only solar power you might need something with a bigger solar panel. This unit takes a long time to charge if you rely solely on the sun. If you charge it via USB and let the sun keep it topped-off you'll be in good shape for charging most devices. At full capacity I can get 50-60% charge on my Samsung GS4 if the phone is totally depleted. That's not too bad if you're in a pinch but for more frequent charging I would recommend the Orange Joos.
