Using a small heater with Trailer

[Reubal]

If you want to get heat from a 12 volt battery there's the https://electrowarmth.com/products/bunk-warming-pad-non-fitted-36-x-60
They use to make larger sizes but now only 36″ X 60”.
You'll probably get 2+ nights sleep per charge of your battery.
We had a queen, then a full, and got 2+ nights on two 12volt deep cycle batteries mounted under our teardrop.
They put out a lot of heat.

Thank you so much for pointing this out. I have a fantastic electric blanket at home, and was going to get the same one for camping, but am unsure about the real power draw. I imagine one made for RVs would be better for the application, so I will give this a shot.

The blanket shows 6.2A draw, but that it cycles for comfort? Even at a steady 6.2A, it should be good for about 25 hours on a 200AH system. I'm pretty sure my home electric blanket is about 100W+ on low.

We had a Buddy heater years ago and it constantly would turn off because of overactive sensor.
I put it out by the curb for a pack rat to take it.
Glad it’s gone.

If you mean the safety shutoff, overactive is better than the alternative.

Vented units are a thousand times better

but unvented in a pinch, absolutely need to crack a window all the time it's on.
