I am typing this on a sofa using my laptop, using my wireless mouse. The mouse takes two AA batteries. The laptop has USB ports. So the laptop can charge the USBCELL! And to do it I don't have to find the cable, charger, etc. - since none of that is needed owing to the brilliant design of the cells. And this is just one example of how great this idea is.

oh fabuloso. remember all the batteries u ate up with that wireless mouse? that set of speakers? using a usb port to charge batteries is the coolest thing ever. buy multiple sets, these should be worth every penny. and feel good about the environment while ur saving money too!

i ordered these and they are SO worth it -- they are charging as i write off my little USB hub and they arrived very quickly from a shipping address in texas; since they are not yet available in the US i decided to bite the USB, asitwere, and pay the UK price.

my digital camera LIKES them, as well as my little book light.

encourage these guys to start selling in the USA and STOP WASTING BATTERIES! (end of lecture)

This has got to be one of the handiest new products yet. Rechargeable batteries that uses your USB port for recharging. Remember the time you ran out of batteries on a trip? No recharger and not enough time to get to a store? As long as your have your computer, you're golden.

WOW This is so cool! I love it, dont need a battery charger and I know plenty of places where I can get a USB plug. This is a great idea. I think it has my recommendation.

Another USB gadget, but truly useful: a pair of AA rechargeble batteries using USB plug.
For 15 euro. (via Trends Now)

Totally great! I can't wait for these to be available in the US. So many of my gadgets require batteries I had to set up a special budget just for that.
