Using a Crock Pot on inverter voltage

I know of someone who tried to use a Crock Pot slow cooker while they were driving and the inverter was supplying the 110 voltage. The Crock Pot's electronics burnt out. Thinking they just had a faulty pot they returned it and got another one. It also burnt out.

We were wanting to use a crock Pot while driving so I contacted the manufacturer and ask the question "Can you use a Crock Pot while on inverter voltage" and this was their response:

Thank you for contacting Crock-Pot, a brand of Jarden Consumer Solutions.

Thank you for your email we are happy to assist you. I apologize however we cannot safely recommend the use of any type of inverter or adapter with any of our slow cookers units for use outside of the home as described.

We appreciate your business and are happy to help if you have any further questions.

Sincerely,
Jacob

Jarden Consumer Solutions

We have used ours many times while traveling. We do put it in the sink in case of an emergency.
By the time we stop for the day the smells have overwhelmed me and I am starving.

I would suggest looking for old style no electronics model possibly yard sale or thrift store if one cannot be found new.

No need for fancy controller

I would prefer using the onboard generator instead as using it regularly is much better than letting it sit idle. It can also power the fridge and roof airs/heat pumps at the same time with minimal fuel usage.(usually 1/2-3/4 gal per hr) 9 times out of 10, our genie is running when we're moving. Inverters are nice to have but can be problematic for some electronic devices. I personally don't think that the ones in most rvs where intended for use by heavy demand electronic devices.

Most appliances with electronic/digital controls can't/don't live with MSW inverter power for very long.

Exactly.

New electronic controls are far less expensive to make than the old style bymetal click controllers.

Locating the old style unit should fix that.

We have an older style off/low/high that we bought @ Wal-Mart just for the MH. I set up a separate Marine invertor in the small basement bay, in a drip pan, just ahead of the entry door and let it cook away without "stinking up" the house.

You all are making me hungry imagining the good smell front a slow cooker while traveling.....

Non electronics model on our 2300w MSW inverter.

There are two kinds of crock pots.. ONe kind has "Electroincs" and the other has mechanical thermostat and a resistive element, nothing else.

There are two kinds of inverters. MSW and TSW.

NOW: if you have a ture sine wave inverter with the capacity to handle the slow cooker.. IT WILL WORK, period, end of discussion, no damage, it will work, does not matter which kind of slow cooker.

IF you have a slow cooker with a mechanical thermostate and resistive heat element and that's all,, IT too will work, no questions ask, Does not matter what the inverter is.

BUT if you have a slow cooker with ELECTRONIC controls

Same for coffee pots
Electric blankets
LED night lights
and many many other things (too many for me to list)

Xantrex on the X-power site used to have a document, "Things that might not work well with an MSW inverter".. It was a long document.

On the Prosine (True sine wave) site the list of "Things that will not work with a TRUE SINE WAVE inverter" does not exist, becasue the list is as follows:

Any device demanding more power than the inverter can produce.

That's it folks The entire list

I have used my slow cookers on TSW inverter many times, likewise my Microwave, my Coffee pot (it has electronics) my electric oven (Mechanical T-Stat and resistive heat element) and a host of other stuff.. Some (this computer, Television, DVR, ATSC converters, Sat receivers, Radio) are Electroinc,, Some (Mixers, fans) are motorized, Some (like the oven) are just resistors and mechanical T-Stats, all work 100% normally up to just over 2,000 watts (I measured it at 2040) more than that and .. Well, that's all the inverter an invert (2,000 watt model actually delivers the full 2000 and a bit of change)

So the moral: They should upgrade their inverter to a TRUE SINE model or get a cheaper slow cooker without ELECTRONICS Either solution works.

I planned on using a slow cooker placed in the sink when we go fulltime and thought I would just use the Genny if its hot out I will be using the Genny anyway for the AC. I don't mind the smell of a pot roast cooking all day, its the same as in the S&B. Yum

BigD... the consensus is Pure Sine Wave versus Modified Sine wave... certain electronics have no or low tolerance to the type of electrical pattern that the inverter creates. Pure Sine wave inverters make electricity that mimic your home type system and its AC voltage pattern and the modified wave is less than that but effective for many products including most electronics. I read the VSHEETS note that his NON electronic crock pot functions well on the inverter...mine too. I did install a big pure sine wave inverter in my RV and it is hooked to the house circuitry but I installed several small modified sine wave inverters to use while traveling for products that are not sensitive to that type of electrical difference. How do you know if one item is sensitive and the other is not....one article says if the electrical device has an AC motor in it...and electronic switch...use only Pure Sine wave...but I am still clueless.

You might look for a 12 volt (DC) model. Several years ago I bought one from Camping World. Slow Cookers don't use much power and the 12 volt unit worked fine until a crimp connection between copper wire and the resistance heating element failed.

My actual question to the Crock Pot people asked if either of their models, the manual or the digital, were able to be used while operating on an inverter. I further asked if a pure sine wave inverter was OK to be used.


Their answer,
Quote:
"...we cannot safely recommend the use of any type of inverter or adapter with any of our slow cookers units for use outside of the home..."
(underline and italicizing by me)
indicates NEITHER one of the Crock Pots should be used on either type of inverter.

Now, we, in the years past, have used a good old fashion manual Crock Pot and had good success with it. This question to the manufacture was really just see what they would say just in case they changed the way they made these things. I thought their answer was a disappointment and thought you guys should be informed.

The big truck stops usually have a whole range of 12 volt appliances and such.
