Thanks for you info. And it's very useful. I found that YB-E5008 has only 3.6V/1100mAH. http://y-toshenzhentech.itm.com.cn/532951/solar-charge-yb-e5008-for-mobile-phone-mp34.htm Well, I have to re-check it with factory before I buy one :) > > You have to be aware of these constraints as well: > - You can't charge your phone while you charge the charger itself YL-S** series can charge your phone when the charger is charged with solar energy board :) > - If the charger is not fully charge (the light is not green), it > won't charge your phone, _at all_! Humm, I have checked with factory. LED of YL-S** series only indicates how much battery is left. And even it shows red, it can still charge the FR. 70%-100% Green 30%-70% Orange 0%-30% red Of course, I think we had better to test it.

They have larger capacity 3.0/3.5/4.0Ah But the price is a little bit higher. :) > > Regards, > Chris > -- Daniel.Li <lida_m...@163.com> PALFocus (http://palfocus.oicp.net) _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
