One of my serious concessions when selling the camper was losing out on heat. So far, it hasn’t been necessary, but the seasons are a changing.
So I bought a RV mattress pad that runs off a cigarette lighter. It was $90 on Amazon. Much more than a house model. And in retrospect may not have been the best choice.
The instructions make a big deal of pinning it to the mattress so it doesn’t bunch up and start a fire. I will have to improvise something to keep it taut, but can’t exactly pin it to an air pad.
But I didn’t want to risk running my battery down so I invested in a battery power pack that I hope will be enough to power it. It is the Enkeeo 222w and I got a really good deal from watching a Enigmatic Nomad review that included a discount code. So it was only $153.00 plus tax. It usually runs $220, but the code has expired, sorry.
According to the mattress specs it uses 12V on high. I don’t plan on running it all night or on high, just to keep the worst of the chill off. But I should be able to run it three hours on high, or all night on low.
But as you can see, this device has 110 plugs. I could saved about $50 by buying a regular house model but they don’t list the power draw, so I couldn’t do the calculations. It comes with an adapter that is a female ciggy receptacle.
This device comes with a charge by house (110), charge by car ciggy (12V), or charge by solar panels (MC4). So now I need to figure out where this will ride and recharge while driving. Plus fit in the snow chains we bought just in case.
This also has the possibility of running all kinds of accessories and even would have been handy in the PG&E outage we recently experienced. 24 hours without power, and we were luckier than most. Wouldn’t you know it arrived the day the power came back on and needed to be charged up.
Edit: So I got out the sewing machine today. I sewed a strip of fabric to both long sides, creating a tube for the air mattress to slide into. The wires were far enough from the edges to do this easily. Anyplace where the wires would overlap is separated by a 3.5 inch air pad. Even if my body compresses it slightly, it would not be on the edges, but in the center. I think this will be sufficient to keep it taut enough. The pictures show what will be on the bottom. The top is pure white mattress pad.
Double edit: used it one night in Bishop. On high it cooked me out in just ten minutes. On 2 it was just about perfect. Face and hands still get cold, but it works well, considering. I don’t know if the car charging the Enkeeo is going to work if it gets too depleted. I only ran it down one quarter, and 6 hours of driving didn’t bring it back to full charge. Need to research that more.
