The XTAR MC4 is a 4 port lithium-ion battery charger with many advanced features. The MC4 input port is based on the Micro USB port so it is compatible with cords you already may own. This is very handy in case you lose the original cord! The MC4 is compatible with a 5V USB power supply so you can easily use this at home while plugged into a wall USB power outlet or even in the card with a USB car charger. The MC4 can even be powered by solar panels while you are outdoors! The MC4 is compact but is still able to charge 3.6/V3.7V Li-Io, IMR, INR, ICR batteries in sizes 10440,14500, 14650, 16340, 17335, 17500, 17760, 18350, 18490, 18500, 18700, 21700, 22650, 25500 and 26650.
