No, I mean the jumpstart packs that have an inverter (120V AC) built-in so you can just plug your existing heater (oil) in. It probably wouldn't work very good because I think they are only around 14Ah. Unless there were larger packs... basically thinking it is something that you wouldn't have to have in the car all the time.
Here's one on Amazon -
duracell unit
Says it will take 480-watt continuous through the AC sockets, so probably wouldn't work.
