I found this amazing product its called USB Cell Batteries you can find it here at firebox.com the idea of it is you can plug it into a USB port by taking the male part of the battery top off which reveals a USB male connector which you can plug into any standard USB port which will then charge the battery.
Its a amazing little gadget all ‘Geeks’ must have this your out and about come across a small computer you can just plug it in or at college/school go in the IT room and plug it in, this product can save you so much money compared to actually buying standard AA batteries.
They also have a few others in the making such as Triple A (AAA) and also the 9V batteries.
You can buy it at firebox here USB Cell Batteries its a brilliant price and worth it!
Cool Idea, A little pricey though.
Im sure a regular charger would be faster and can do multiple batteries at the same time though.
I wonder how they can do the head for the AAA ones they are smaller then a USB connection.
The AAA ones have are like micro USB drives, their isn’t any metal around the sides.
.
You can get super chargers for special batteries that will fully charge your batteries in 2 hours, but the USB idea is much better i think just plug it in any where you go
I think this might be a better option.

Also I can actually get those USB batteries for about half price.
I haven’t actually brought any yet waiting for AAA to be released
