Question electric blanket?

How much power does an electric blanket pull? I don't think it'll get all that cold next weekend. Would an electric blanket be practical?

It'll pull plenty -- but would be okay if you have a 120V 15A hookup. I won't be camping next weekend. Where you going?

They're typically around 100 watts.

There are 12 volt versions available from places that sell to truckers.

Off the top of my head, I would think the electric blankie would pull less power than a comparable amount of furnace running would do to your batteries (I assume this is a battery question).

You would just need a small inverter.

A quick search on the internet came up with 12 v electric blankets. The smaller version (I'm assuming single bed) is rated at around 50 watts and draws 4.5 amps. The larger version is rated at about 80 watts and draws 6.7 amps. These are both pretty hefty draws. A 100 ah battery in good condition fully charged would likely only provide in the neighborhood of 10 hours of operation. Because of the ineffeciency involved I would guess that a 110v electric blanket of comparable wattage running off an inverter would mean a shorter operating time. Here is the URL for the 12v blankets with a discussion about how long a battery might last. 12-Volt Heating: 12-Volt Heaters & Electric Heating Blankets

Doh! Good point... we will have hook-ups. No worries there. We are heading down to the Vintage Rally in Montgomery, TX.

Thanks for the info! I have so much to learn.

12V pads

I just purchased two 12V electric mattress pads for the Fla. State Rally. We just about froze our asses off last year because our furnace is broke. Rally electric (3 amps) is supplied so don't know if this will work but we sure are going to try. According to my calculations, the pads should run for about 8 hrs. Batteries should recharge during the day from the 3 amps. I also bought a Buddy propane heater!

Electric blanket current draw

We found one tonight for a friend -- a full-size bed's electric blanket is rated at 180 watts 120vac. This is just one example but thought a specific anecdote might help.

Very best,

Jim

If you had power, would you prefer the electric blanket or a space type heater??????? Think that we would prefer the heater - late night potty visits.
If you don't have power don't you just load up on blankets and quilts????

elec blankets NO

Power or not, we wouldn't choose electric blanket. I married an electric blanket. The difference, for us, between overnight temperatures is whether we have a one, two, or three blanket night. Whichever, we are toasty.

Oh yeah, and those midnight walks to the w.c. We keep the camper at 45 to 50F overnight with the furnace, so we can stand the brief visits.

This morning the outside temp is 44F and we are 52 indoors. Furnace never came on last night although we had it on 50. I'm sitting warm in front of our catalytic heater with a cup of hot tea and working the ham radio on our RV SVC NET morning talk.

Staying warm in Okeechobee, FL,
Jim
