I have used a simple heating pad to warm myself up when I didn't want to run a space heater or the main unit. The heating pad I've got is big enough to cover my thighs, or most of my chest/stomach area.
It only uses 40 watts so that's a pretty efficient way to warm yourself. Put the pad against your shirt, then overlap your coat or a blanket on top of that to seal in the heat, and you'll be toasty warm soon. Heating your core like that makes a big difference.
If you've got some automotive or other large batteries to use with an inverter, you'd probably get hours of use per charge.
