Here is big suggestion...I fly RC airplanes you can get Li-po batteries at local hobby shop and charger but cost more.mail order places like BP hobbies and dealxtream has cheap lipo batteries for phone you only need 10c this is discharge rate also cheep charger.about 20 bucks will get charger and batteries.lipo batteries last way longer and have a lot more capasity I can use mine for days and only takes 15 mins to recharge lipo with two you never run out of power and won't have to buy batteries for long long time

i tried to make this with solar panels but couldn't figure it out. so can I just use multiple 9v batteries together (I have bunches) and have it charge my phone in a few hours. I would use this in an emergency though so great idea.

I made one but I used a USB car charger, and a 12v car socket adapter which I just clipped to the 9v battery. Charges my iPad 3rd gen and my Droid Razr M just fine! Thanks for the great idea!

Nice charger, but very inefficient. Everything over 5v is lost as heat :/ i recomend getting a dc-usb step-up converter instead (they cost about 2$ @ ebay w/shipping), and use it with two AA batteries ;)

Hi, which is the brand of your usb car charger? It's because the ones I've found, can't be opened. Thanks
