Building a solar phone charger

[QUOTE="Steve619, post: 5415285, member: 585636"] Hello. I am building a solar phone charger and have decided to use 3 Nimh batteries, a 5/6 v solar panel, a usb 5V rectifier and also a Lipo credit card rechargeable cell. My reasoning is limited for this build as the more I read, the more conflicting info I find... (Eg, charging AA batteries is easier with solar than Lipo's, then I read its harder)... So I am somewhat confused but my design has been decided on. What I am really after is info on how quick I can charge the Lipo cell off the AA batteries and will that cut off, overcharge function be built into the rectifier... I am buying a rectifier specifically for phones. (Although not sure if it will do Iphone or not) And also any assistance I can get that would make this project amazing instead of just ok. Cheers [/QUOTE]
