You can get 9 to 12 volt DC wall-wart power supplies for very little cost, probably less than a cheap 9 volt battery would cost.

What I'd do is rectify the heater string (or feed it to a voltage doubler) to power the fan....It's less bulky, and comes on with the set, and I can make one out of the stuff in my junk box anytime.
