12 volt mattress pad warmers

A couple years ago there was a thread on this forum about 12 volt mattress pad warmers, and as it turned out, nobody was making them anymore in any sizes except very small. Those of us with full-size or larger mattresses were out of luck.

I've just discovered that ElectroWarmth has them available again at http://electrowarmth.com/shop/

We use a 120 volt one at home and love it. The room temperature can drop down in the 50s and we stay toasty under the covers. But that mattress pad warmer will not work on a MSW inverter, so we either have to stick to shore power when camping where we need that heat, or we have to run the generator all night (nope, not gonna happen).

I sprang for the full-size queen pad with dual controls, and while it was spendy at $202 with shipping, I think it'll be worth it. It draws a max of 3 amps, and will save us on propane on those cold nights when we don't need to run the furnace to stay warm in bed.

I dunno why they reintroduced them, or for that matter why they discontinued them earlier, but TODAY they are available again. Get yours while the gettin' is good.

  • We have discovered that even when the interior of the trailer is in the low 20s (yes, we have a thermometer), we are fine without any heat source during the night -- just a thick down comforter and a couple more blankets on top of that. The problem is getting out of bed in the night and in the morning -- we wear Russian lamb's wool hats and lots of warm clothing. And yes, that is a buildup of ice on the inside of the window behind DW:



    How cold does it get? Once, the cord on our coffee maker froze -- this is not a trick shot:


    On second thought, that 12 volt bed warmer is sounding pretty good!

    We have a couple like that but my wife hogs the heat controller.

    (Yes, that's what the band is named after).

    3 amps at 12V is 36 Watts.
    Not going to keep you toasty I'm afraid.

    Did you actually speak with somebody at ElectroWarmth who confirmed they have the 12V queen size mattress pads again?

    It appears to me that the all of ElectroWarmth "mattress pads" are 110Vac, and only their "bunk warmer" is 12Vdc... I did see the sentence on the queen page that says 12V, but I suspect it's a typo' :(

    Or get a Psw.

    By comparison, my Sunbeam 120v dual zone draws 180w per side. The 12v one is 36w. Fyi.
