Running Crock-Pot on the batteries - Page 2

NMWildcat · 10-09-2016, 08:20 PM

I can tell you from experience that a 400watt inverter did NOT run any of the crock pots we tried it with, even on low settings. It would pop the overload protection on the inverter within a few seconds.

Most inverters that dare claim 400 watts do not do this with a cigarette lighter connection. You will find a pair of big alligator clips in the box as well. Cigarette lighters are not capable of the required amperage.

You may well be correct. The largest thing I have run from the cigarette lighter with my 400 watt modified sine wave inverter is a 2.4 amp load.

I guess that's about 288 Watts but I also run a DirecTV box on my cigarette lighter inverter all the time without a problem.

I run my 2001 pure sine wave directly from the batteries with the 3-foot 2 gauge cables. And, if I was planning to run at higher wattage for any length of time I would rewire it with 2-0 cable but before I would run heavy loads for any length of time I would have to install two more golf cart batteries.

I think you dropped a decimal. 2.4 amps x 12 volts = 28.8 watts.

ScottBrownstein · 10-10-2016, 12:41 PM

Not on the ac side. That is about 288 watts at 117 volts

Rockfordroo,

The watts don't change on DC the amps do. Multiply amps by 10.

I was assuming he meant 2.4 amps at 12V, since those were the amps we were discussing. He wasn't very clear.

We tried running a small crockpot with a 200 watt msw inverter while underway... the vintage small round crockpot we have fits in our round sink, and we used the cigarette lighter connection from the "over the door" tech cabinet on our 2017 SunSeeker MBS 2400 W. Only the low setting was possible... on high the inverter "tripped out". The crockpot is rated at 400 watts for full power, no rating for low.

I noticed there was one open 12 volt circuit in our power panel, so we got a 500 watt msw inverter, and I installed it on that circuit with a 30 amp fuse. I have read elsewhere the these appliance watt ratings are often overstated, so my hope was that the actual crockpot draw on high would be less. The new inverter has a readout for the load it is supplying in watts, along with the battery supply voltage... we lucked out, with the load on the high setting reading 270 watts. While underway, with the engine charging the batteries, this slow cooker set-up works great. When we stop, we can watch the batteries die, with the charge getting down to 12.1 volts in maybe 1/2 hour to 45 minutes... I have been keeping those stock batteries watered and charged, but I do not think the 2 of them can produce anywhere close to the 80 amp hours they should before dropping below the safe 50% discharge.

I know this does not directly answer your Tailgating question, other than to back up what others are saying about your need for a more robust battery bank to even get started with the slow cooker. My slow cooker is pretty small, an at the high setting 4 hours of operation would use about 100 amp hours, plus the at least 20% efficiency drop inherent with inverters.

Let us know what you end up doing.

I have often wondered if installing this https://www.tesla.com/powerwall in a motorhome would be an option, it would seem useful ln a tailgate or race track setting where the generator noise might be prohibited. I wonder how long it could run the rooftop a/c for the night etc.I also wonder if they could bounce down the road and stay in tact LOL.

I know if I was a race fan or other event type motorhome user I would be looking into it.

Don't fall for the hype.

ScottBrownstein · 10-13-2016, 10:35 AM

Funny. Originally the whole idea was to recycle Tesla battery packs when they dropped below 75% capacity. On the road that loss of range is a problem. So...it might have already spent a lot of time "bouncing down the road" anyway.

Does it make sense to charge a battery to charge another battery????

And they want several grand to do it.

And Tesla hasn't turned anything even CLOSE to a profit yet.

That's hype to me.

I was thinking if you had the tesla unit and you were at a race track using your generator all day, a lot of people have to turn them off at night so you can't run your A/C at night, having the unit may let you run the a/c for a long time into the night. I was thinking the motorhomes used by people that really are not concerned about a couple grand. According to what I have been reading the Tesla wall unit would provide you the 110 you need.

As far as not turning a profit I don't know about that or care, i think Musk has pretty deep pockets so I think he is shooting for something out of the ordinary.

Wouldn't that unit charge up from your generator during the day?

I never said anything about charging a battery from a battery, not sure where you are getting that.

If you've got deep pockets, it would probably work for what you're describing.

I believe part of their advertising was you would use them to recharge your Tesla in your garage, hence "charging a battery from a battery."

DXSMac · 10-14-2016, 07:30 AM

I once knew of someone who would run their generator while they were driving just so they could plug the crock pot in and have dinner ready when they got there....

funfinder5 · 10-22-2016, 09:46 AM

I like the old school simple approach... Heavy case iron pot with lid on the propane stove set very low. Could run for a week without draining your batteries!

Someone here once posted about thermal cookers. I'd never even heard of them. Here's a link to one of them.

Basically you pour some boiling water into it and 6 hrs later your food's cooked.

Google "thermal cooker" and you'll get some other brands.
