I want to charge my mobile over USB from AA/AAA batteries. My google fu is weak, can someone find a product that allows me to do this?

"aa battery pack with USB out"
Though sounds hideously expensive compared to a rechargable battery pack
There's a reason for that. Its going to get through a lot of AA's, 6-8 decent ones for a Samsung phone!
If you plan on using it more than once then that anker one above will work out cheaper and probably lighter than carrying a bazillion AA's to charge your phone in the middle of nowhere.
Thanks both, I bought the Maxell one.
I understand the limitations but I've got a gazillion AA rechargeables lying around, seems criminal to buy even more lithium when I'd got so much sitting about under-used.
