View Full Version : Question about heating blanket hooked up to inverter
01-16-2012, 03:52 PM
I'm going on an overnight wheeling trip. I will be sleeping in my Suburban. It will be in the teens at night. I have a 1500 watt inverter. The blanket is a dual control queen size. It's overloading the inverter though. It says 135 watts. But I also says 613A. That's a lot I think. Do I need a larger inverter or am I missing something here? Thanks!
Sorry about the sideways photo.

I figured it out. I need a bigger battery. Since its just a temp thing. I am using a powerchair battery. I first had a 12V31ah in there. I switched to a 12v55ah battery. Its a lot bigger. Testing it now to see how long it lasts.

Good luck with this. We tried to use a Heated Blanket when we first started out. I called the folks who installed our system and before I could even get to the root of the problem, he says "Let me guess, you're trying to use a heated blanket?"
From what he explained, most electrical systems have some sort of brain, per say, that tells them how to regulate their power consumption. Heating Blankets, Coffee Makers and Microwaves don't have this. They all just turn on and suck 100% of the maximum watts at all times. So those are the worst things you can use. He mentioned other things like Curling Irons, Hair Dryers and a few other items that I'm sure don't pertain to the Overland World.
I know when I'm in Truck Stops, they offer 12volt Heating Blankets, and I've always wondered if they wouldn't use as much power? Just never got around to trying to experiment with it? Oh, we have a 2000watt Sinewave Inverter and 4 AGM 6-Volt Batteries run in Parallel. It sucked them dry in a matter of 20 minutes trying to run a standard queen heating blanket!
Let me know what you find out
