Another great option from XTAR: 

The XTAR XP4 Panzer Lithium Ion battery charger is capable of charging both Ni-MH and Ni-Cd batteries. The product's independant four slot design allows it to charge four different size batteries at the same time. The XP4 also has an additional capability of being used as a power source through its integrated USB Port. The battery recognition system is also designed in such a way that batteries can be discharged in one slot, while other batteries can be charged in another.

This kit includes a car charging adaptor to allow for use in a vehicle.
