The power/solar/batteries/generator thread

[Irving]

How fast do those solar charges work? The reason I ask is because I've noticed that the USB charger from my old stupid phone, charges my new Smart phone so poorly, that it only maintains or slows the battery going down. It won't make a positive charge at all. I suppose it could be bad, but it turns the phone charging symbol on like it is supposed to, and seems to still charge the old phone.

On a sunny day, my 5 watt solar usb charges the iphone roughly 1% per minute, the ipad around 8-10% per hour.
