Markodevil,
Hey I got an XTAR MC2 I got from US a while back, and I was wondering if this charger would work for the warrior tier batteries. As I live in Australia so the micro usb on the XTAR is easy to use, while the wall charget with an American plug will be a little more difficult.
Mate, you should be fine.
There's every likelihood that the Warrior Charger that's included with your Order will be suited with Australian Prongs for Australian Outlets. Even if it's not, whilst the Micro USB Port is handy, getting your hands on a Universal Plug Adapter is pretty easy too.
Try places like K-Mart, JB, Officeworks e.g.
