Yes, we really still use these dang AA batteries that eat up power like hungry termites in a forest. However, we don’t have to be their slave anymore as the USBCell Batteries from Moxia work for us and not against us.

All it is a cap for the AA batteries that can be recharged via USB. To be honest, I’m not certain why I haven’t seen more of these, but it takes 1-2 hours to charge it, and it is good for about 7 hours of use.

Not certain how much this costs or the availability date, but I certainly think it’s quite useful.
