Nimh battery powered usb charger?

RaVeN38571 · Nov 24, 2009

I was wanting to know if there is a device you could put nimh batteries in and charge another device using usb? It would be kinda like a external battery pack for a cell phone or pocket cam.

Most of the mobile cellphone chargers do just that. The Duracell Mobile Charger can go both ways, using AC or DC input to charge NiMH cells, or using NiMH cells (or primaries even) to charge USB devices.

I really dont need it to charge the nimh batteries. I would assume if the charger wasnt built in, it would be smaller.

Then you have dozens (if not hundreds) of different mobile cell phone chargers to choose from.

I was going to suggest that. I made one for my iPod. It is a neat project.

You know you don't have to build them, right? You can pick them up in any store that sells cellphone accessories...
