USB Rechargable Batteries?

I'd rather just get rechargeable batteries that use a wall charger. These are a really cool idea, though.

Agreed. I could only see these being useful if you travel tons. Regular rechargeables are a much better investment.
 
i dont get it... a AA battery is smaller in diameter then a standard USB port... how does this work?
 
I love these things. They are perfect for my wireless mouse and keyboard. I rarely use batteries for anything anymore since most gadgets have lipo batteries now. I also just don't want to deal with having a bulky charger (that I inevitably lose) if I only need 2 AA's at any point in time.

i know what you mean. however, every 6 months to a year i seem to always find a 100pk of alkalines for like $12 so i have just been going that route. there isnt much easier then just throwing crap away all the time.
 
Damn, I'd love to have some of these just as backup until I take the time to buy some more/recharge the ones I have. :)
