The USB Battery Charger works as any other battery charger, but instead of plugging it into the wall socket you need to connect it to your computer via USB. It can handle 2 or 4 batteries, be it AA or AAA sizes, Ni-MH or Ni-CD batteries - it will charge and charge and charge…

In case you are interested to give new energy to some batteries and don’t have/don’t want to buy an expensive charger, there is a cheap option which costs $15 at GadgetWorld.
