just some advice. These chargers are that good. In fact even if you live in iraq with 24hr sun you will have a hard time charging it up.. I have 2 solio chargers and I they take about 2 days of full sun to charge up, and each one only charges my Droid one time. so I get to recharge my phone with them every other day. The solar cells on these are cheap and very low power, if you just want an extra battery to carry around? cool. But don't think these will keep your phone charged. :lifting:
