Battery charging question
I saw a recipe where one would put your crock pot in the sink and cook while traveling. Will my batteries be charged by my truck will driving down the road?
Forum Discussion
- Is your crock pot 12 volt?
- We can guess, but you can find out by hooking up and putting a voltmeter on the battery.

X-2, if not, then your crock pot won't work, UNLESS, you have an inverter.
Is your crock pot 12 volt?- Yes a standard 7-pin connector includes a 12 volt connection to charge the trailer battery.
Do verify that it works. Trailer battery voltage should rise a bit as you plug into the running truck. - As stated above, your tow vehicle can provide a small charge to your RV's battery through the 7 pin connector, only way to know for sure is using a voltmeter on battery while tow vehicle is running, there should be a noticeable increase in voltage if a charge is present. Without an inverter your crockpot must be able to utilize 12 volts DC to actually function, they are available at Cabelas and Bed Bath and Beyond to name a couple of stores.
- A crock pot uses about 200 watts...so isn't that about 16 amps the twelve volt system would need to produce to run a 120 volt crock pot through an inverter?
- After looking up wattage for an average crock pot, I find on low, 200 watts, on high 325. On low you would be taking 200 watts, that is about 16 amps, taxing the charging wires from the tow vehicle to the RV unless you have up the wiring.
In short, if you draw too much current you might blow the fuse protecting the wiring, or if the fuse is too big, you might overheat the wiring to the RV. Much better to plug your slow cooker into a regular 120 volt outlet when you are on shore power at the site. Sandia Man wrote:

the underline subject has been discussed here several times in the past few months. The short answer to the question of re-charging a TT deep cycle battery from you vehicle is probably NOT ! You would need more than 14V to properly charge (and a good charge controller) to charge a deep cycle battery and you are not going to get that.
Running a inverter is similar, but not the same. Inverters will usually keep running down to some where between 11.0-11.5V. The problem is, if the voltage temporarily drops below that and the inverter shuts down, will it restart when the voltage comes up to 12V ?- Put the inverter in the tow vehicle. Run a 120 volt line to the RV. Plug in the pot.

Alternately, put the inverter and the crock pot in the tow vehicle, and enjoy the delicious smells as you travel.
