When I wrote about the USBcell battery it appeared to be the only one available.
Now, another USB battery is on the market. I’m not sure if ‘Super Cool’ is the name or simply a description. There seems to be a derth of information about these batteries. They are less expensive at $7.51 USD a pair (AA). USBCELL is 10.99 (brit pound) a pair.
USBCELL, oon the other hand has news. For one, they are working on more designs, AAA, C and D size convertors and more styles to come. Secondly, USBCELL has become involved in the Clinton Global Initiative
