Slow cooker on the road

That supposedly uses 78 watts, don't know if it is too small for you though.

 

I use a lunchbox cooker just fine. Canned stuff

 

Sorry for your mishap, OP.

My RoadPro slow cooker works great.

Good luck with your search.

 

I used to used a little crock pot slow cooker and a 300/400w inverter.

It was a little two quart model and it taxed the inverter.

It really depends on the quality of the inverter, AND where you get your power supply.
If you can tap the batts, it'll likely work fine.

Mine was a cig plug and I can tell you for a fact that it did cause the plug to burn out.
I was watching tv on a break and heating some grub when I smelled wire burning.

That was the end of that.
I did it for a long time before the issue.. but it could have been a mess.

Bought a 2k watt and wired it to the batts. Use a microwave now.

 

The problem is that inverters without an APU can damage the truck batteries. You can still use an inverter, but make sure your engine is on and idling at 900 RPM or more. Some people have their slow cookers running while they’re driving. Just keep the slow cooker next to you in case you need to turn it off.

Personally, I would install one and not tell the owner. Just make sure you don’t use it while your engine is off, and remove the inverter before you turn in the truck (at least for OTR drivers).
