What about plugging your incubator into a dc-to-ac inverter cigarette lighter plug?

I'm transporting my snakes (4hrs of Chicago weather, hurray!) and I have 2ft of 11" flexwatt left over...Figured I would just wire the flex in a box with a triac plug it into an inverter in my car and be done with it. I like over-kill if you can't tell.

I know there are problems with surge protectors in the home...since it can interrupt the ac current sine wave, but since its converting a direct current to an alternating, It should be fine for a thermostat.......BUT(!!!!!) Don't take my word for that!! I'm not risking one on that either! But two feet of left over flexwatt - boo whoo
