I'm thinking about buying a 12 volt heated blanket as a Christmas present for my wife for our camping trailer. I have two 6 volt Trojan T105 batteries. 225ah.
Most 12v blankets claim they draw something from 4.5 to 6.5 amps. Some turn off after 30, 45, or 60 minutes. Some stay on until you turn them off. Some have different heat settings.
Does anyone have experience using a 12v heated blanket? I think my wife would enjoy using it if it works well enough. Would I risk drawing down my battery too low when dry camping for 3 or so days? (We're pretty frugal with our battery since we don't have a generator or solar)
Anyone else using one? Any positive or negative experiences? Brand recommendations?

I used a 12V mattress pad in the truck. Never ran down the starting batteries to the point I had issues cranking the Cat, even over a weekend layover.

Depends on the SOC of the Trojans each individual night when you retire whether that amp draw will handled well by the batteries, and how you recharge. Solar? Eight hours at 4.5 amp hours would be 36.

My wife hasn't used hers in years, but it was very popular for a while. It was the type that shut off after 30 minutes or so. Never a problem for our two 6V batteries.

Let’s do some simple math. Taking that 4.5 amp draw, over an 8 hour snooze, we get 36 amp hours per night. At 6.5 amps, that’s 52 amp hours per night. If you have the single 80 amp hour battery most TTS come with, that blanket will completely drain as much power as you dare or even damage the battery. You need to check you battery AH rating before deciding.

Have one stuffed up in the cabinet above the bed. DW has used it to warm her side before turning in or has used it on the sofa as a warming pillow. IIRC only used the first year or two. Stays along for the ride if needed but I think it is long forgotten.

We use a regular electric blanket under the mattress pad. We keep it on the lowest setting and keeps us nice and warm. Two 6V and solar, very little draw.
