Running Crock-Pot on the batteries

jjlavin · 10-09-2016, 10:55 AM

In 2 weekends, we are doing a tailgate and I would prefer not to use the generator out of consideration of the people around us. My goal is to get the Crock-Pot cooking for 6ish hours off the batteries - I would use an inverter off the cigarette lighter adapter. I just checking the power that my Crock-Pot consumes. 2.25 amps, 278 watts.

My question - will my RV batteries be able to sustain that kind of power for 6 hours? I have a 2015 Sunseeker 3010ds with the factory batteries.

I'd cook it at home and then warm it up at the party

Less work there, less drawdown on your battery = win-win.

Cigarette outlet,Very Bad idea! Run Genny,or Cook before and heat in Oven!

Youroo!!

Your crockpot will draw over 23 amps at 12v DC (the 2.25 amp rating is for 110V AC). I don't think there are any cigarette lighter circuits that can handle that much current...you will blow the fuse protecting the circuit.

278 Watts at 12 volts - about 25 amps (with inverter losses). Unless you have a huge battery bank, you will kill your batteries in short order.
12 volt amps are over 10 times 120 volt amps, FYI.

With losses in the inverter, you will be drawing over 25 amps from your battery / lighter outlet for six hours. I will most likely either blow the fuse or melt the lighter outlet/plug. In addition that is 150AHr which is is way more than most standard battery set ups can support. Cook at home then heat up on propane stove .

Even if you bypassed the 12v socket circuit (wired directly or whatever), you would need a minimum of a little over 400Ah battery capacity for this one task alone.

In simpler terms, your looking at about 4 6v golf cart batteries to safely handle that single task.

Simple answer is no

Have you thought of getting a 12 Volt slow cooker? Amazon shows quite a few different models.

**Flybob** · 10-09-2016, 02:14 PM

An crock pot with equivalent capability will still require just under 300W or about 22A so you will have same problem with a 12V version.

What are you cooking? If you had something like a Dutch Oven, you can slow cook on a regular stove and as suggested bring it to the party. If it is cast iron, it will hold the heat it for a long period of time. The enameled version makes life easy.

We have the same rig, year earlier. DW suggests use the propane grill (ours came with rig) unless the weather is against you. Great rigs, enjoy.

From time to time I run a 400 watt inverter off the f250 cigarette lighter with no problems. Still, not sure I would run 6 hours on the truck or the two golf cart batteries in our coach.

Run your generator. Haven't been to a tailgate yet where most everyone wasn't running a genny. But then again, I would cook all I could before hand. 6 hours is a long time

We have had great luck with getting the crockpot hot at home, wrapping the inner pot with towels, so that it is a tight fit, be sure ALL surfaces are covered, and putting it into a good cooler and keeping it wrapped up until its time to serve. (We use a 2" thick foam cooler)The oldtimers used to do this with a pile of straw and a wooden box. If you are using a cast iron pot it holds the heat even longer.

You can plug a 5000w inverter into a cigarette lighter and not blow the fuse....until you put a load on the other end of the inverter that is. Most modern 12v "Accessory" circuits (aka cigarette lighter plugs) are rated for either 15 or 20 amps at 12v...this equates to a little over 200w at the most. It's not my rule, it's Ohm's law.

What if you set up a double boiler arrangement in one of those shrimp boil/turkey fryer things?

Cast Iron Pot (Dutch Oven type) over propane stove is all you need to use and will work just as well. I guarantee your neighbors will not hear this setup ;-)

You may be "running a 400 watt inverter" but are you powering something that's actually using 400 watts? I suspect you're not. 400 watts would be 33 amps at 12 VDC. Most cigarette lighters have 20 amp fuses. So I'm guessing that whatever you've actually got plugged into your 400 watt inverter is actually using something less than 240 watts.
