This is the Xtar MC6
If you've ever used the MC1 or MC2 from Xtar and thought "I need to charge more batteries" you're in luck! The MC6 can support up to 6 batteries at a time with an automatic charging current of 0.5A or 1A depending on the batteries being charged.
It also has a little display that shows the current charging status of all of your batteries meaning you'll know exactly how much juice is in them at any time.
It's got intelligent heat detection that automatically reduces charging current if the unit is getting too hot - safety is a top priority here!
