I use two brands/types of vest/jacket depending on the ride and the conditions;
For shorter rides Summer/autumn weather I use a Oxford heated vest with batteries. The batteries last up to about 3-4 hrs no problems
For a longer ride or typical Canberra winters day i use a First Gear jacket and controller from the States (purchased in Minneapolis at IBR17) and this is powered off the bike. Outstanding! Used in today's commute to Sydney in sub zero conditions and fog. Warm as!
