USB Batteries

Posted by ryuzaki0 on from the novelty-items dept.

An anonymous reader writes "Tired of paying for new batteries all the time? Tired of searching for the charger for your rechargeable batteries? Worry not, because these new AA batteries will recharge direct from your USB port! This is such a cool idea, that I cant believe that no one has done it before." At $24 each I would hate to lose or break them on a regular basis.

    In most cases, if you have USB power you have an outlet. In rare cases where your out in the middle of no where with nothing but a notebook and a GPS unit running on AA batteries, and you need to keep the GPS charged so you can make it out there before dark, I guess these would be of use. Cant realy think of any other time.

    Unless the electronics are really well engineered (aka foolproof design) then a failure could result in a damaged motherboard, especially considering the amount of current these things are capable of drawing. Surface mount fuses aren't much fun to replace, especially in laptops. I'd wait a while to see if any horror stories surface before plugging that thing into my machines.

    On a related note, the Motorola Razr cell phone's power connector is mini-USB, so it can charge off of your USB port as well.
