Heated mattress pads and generators don't mix!
I called Biddeford Blankets about a new controller for a heated mattress pad we have had for several years. During the conversation the lady in customer service told me something that you may not know.
She said that electric blankets and heated mattress pads that used electronic controllers should NEVER be used on a generator or inverter! I don't remember the exact reasons she gave but she said that it would ruin the scramble all the programming in the controller.
I had never heard this before and I'm guessing a lot of you have not either.

I believe it's the difference between modified sine wave inverter and sine wave inverter. I believe modified runs most things but can ruin some.
I would recommend maybe a 12volt heated blanket so then you dont need to worry about it.

We used a older heated blanket a lot in the coach during our snow ski trips. It was plugged into the modified sine wave inverter outlet and didn't have any problems for years of use. Then we got a new electronic silent type of heated blanket and it would not work at all unless we were plugged in at the campground. I don't remember any problems with using the generator and the new blanket. Alarm clocks were another problem with the modified sine wave. Seemed they never held the time very accurate unless we were plugged in.

She is right about the inverter(at least for her brand) but wrong about the generator in RVs. The gererators in RVs produce the same power as you get from plugging into a standard ac receptacle.

Onboard generators should be clean. Cheap contractor generators may not be quite as clean. Pure sine wave inverters are fine. Modified sine waves can fool electrical devices. Our lap blankets last about a year in the MH. We use the inverter a lot.
Think about this. Many motorhomes have microwave ovens that will run on inverters such as mine. So you can't throw the baby out with the bath water in every case.

Most modern electric blankets will work with pure sine wave inverters, but will not work with modified sine wave inverters. Old style blankets with analog controls will work, but they are very hard to find.
The Soft Heat blanket Best Electric Blankets Reviews | Review Soft Heat Low Voltage has an integral power supply and actually runs from 18V dc. It works fine with any type of inverter. It is also such a nice blanket that I got another one for my s & b house.
