Can I use the power post for cooking

Morning, Im wanting to use a Hot logic or crock pot in my box truck. There's these two black and red power post not being used. The GPS is being run of a cigarette lighter. Im also assuming they are factory . Can I assume they are at least a 15 amp install. And if i make the correct connections on my cooker i can install and remove them daily. and even use an inverter there. The truck is an Intl box truck. i can go either way with the voltage. But i just realized I have a 300 Watt 120 v rice cooker that would work awesome.

 

i can go either way with the voltage. But i just realized I have a 300 Watt 120 v rice cooker that would work awesome. I dont want to make a problem for the company. I guess I need to figure out how much power is supplied there .

 

I found this. conversion
12 volt to 120 ac conversion



Wattage is volts X Amps. A 120 volt inverter needs 2.5 amps to make 300 watts. Power stays the same no matter how you convert it. ( With probably a loss for heat because nothing is 100% effective in converting power) To get 300 watts of 120 volt AC power out, you would need to draw 25 amps of 12 volt DC from the cigarette lighter! ( both equal 300 watts) Does your cigarette lighter have a 25 amp fuse and 10 gauge wire?


The wattage thru a car cig lighter/outlet is limited by the outlet’s amp fuse rating. So most car power outlets are limited to 120 watts (12 V x 10 amps) or 180 watts (12 v x 15 amps) based on most car power outlets having a 10 or 15 amp fuse.

 

Yea theyre in the middle. CB post. So the max I could get is 240 watts of 120 volt power without compensating for efficiency losses , ect. So the rice cooker is out, so is the lunch box cooker. The hot logic draws 45 or 65 watts at 120. Which should be around 4-6 amps of 12 volt. So i could do this with a inverter.with cb connections its well within the limits of the cb connections. And I #### sure wouldnt be getting the alternator and batteries attention. Right?
