The XTAR MC2 is a super simple charger capable of charging many different Li-ion chemistries (see below). The charger can be powered by any USB power port that is capable of providing .5 or 1 amp. Most of the power adapters that we use to charge our cell phones and other devices can provide this. If you have a 12v cigarette lighter USB adapter you can charge your batteries while driving to your favorite flying spot, or If you'd like, you can even charge your Li-ion/Nimh batteries in the field using a Lipo pack as the power supply. We have a very handy Xt-60 to USB power adapter that can help you with that (link at the bottom of the page).
