Using 110 AC Compressor on Road
Hello fellow campers,
I have a 2007, 3400RL, towed with a 2010, F350. I have an AC outlet in my basement and carry a Kobalt compressor with me. The compressor is a 120 volt unit, drawing 12 AMPS. If I needed to air up a tire on the road, could I plug it into the basement outlet as long as I keep the truck running? Or do I need to put in a DC to AC converter in the truck?
I have been wondering about this for some time now and appreciate any advice you have to give.

Do you have an Inverter that takes 12VDC and supplies that outlet with 110AC?

I carry an a similar compressor in mine, but can't get it to start without shore power or my generator running. That's in a 2019 3820FK.

Unless you have a converter in the trailer already, that outlet is only active when you are connected to power in a park.
Get a small converter if you need to at HF or get a 12V/120V Husky inflator at HD.
Or start the generator?

You need an inverter to change 12v to 120 and probably some serious batteries. If I need to do that I fire up my generator and use it for the power.

Thanks everyone. I don't know if I have an inverter but from the conscientiousness of the group, it seems I will need to get and inverter and wire it into the truck as the fiver does not have a generator.
Thanks to all.

You will want an inverter in your trailer vice the truck.

My generators are protable and ride in the back of the truck so it's no hassle.

My electronic theory is a bit rusty, but 12 amps might be a heavy load for an incorrect inverter. The wattage would be in the neighborhood of 1440 watts, a bit more than a microwave. Just my 2 Volts worth.

I have a 2000w inverter mounted on my truck, handy for many things.

It would be much cheaper I think to just buy a 12V compressor. Or I had one that is a combo battery jumper/compressor/light that worked, all be it slowly. I actually burned it up because it would shut down to a sort of 'limp mode when hot and that took about 5 minutes when pumping at around 70=80 psi. I thought I would just 'trick' it and would shut it off and just start up again. Well I now have a nice jump starter with no compressor!!!

This would be a good time to buy a cheap inverter generator. I have a Honda 2000 but you could buy a Harbor Freight inverter for less than half the price of a Honda if your primary goal is to have 110 volt for the compressor yet use the HF inverter generator for other things if needed on or off the rv.

We have a generator in the truck if we would need it. We also have road service which is out first "go to" for on the road problems.

Even before RVing (which for me started in 2006) I went through several air compressors for 4 wheeling, travel, hunting, etc. You get what you pay for. As far as Sears, Harbor Freight, etc., been there, done that. A few years ago this forum recommended ViAir. I did not buy the most expensive one, but it will air up my G614's to 110 psi faster than any other 12 volt OR 110AC compressor (portable) that I have ever tried, and mine came with enough hose to hook it up to my tow vehicle battery terminals and reach the rear of the trailer. Just my $.02.

Just be advised that 12 amps at 120 VAC will be approx 120 amps at 12 VDC.

Y'all just need to get a Viair 400p compressor! hooks up to your battery fill tire up 150lb blow out water lines and all kind of other stuff and you don't need use a jenny. And it doesn't take up a lot of space.

Builderbob is the answer.
Or, just have a generator.

Thanks for all of the info. I have decided to take my 4,000 watt portable genny with me in the truck bed. I am a seasonal camper so it will just be in the bed for the round trip. I stopped taking it after 10 or so years with no power outages at the campground, but last year we had several. As long as it is paid for and a need may arise again, it will solve the problem of an inverter installation.

I had the same issue. I added a 2000 wat inverter (12 to 110) and then plug in a low amp compressor. Amazon sells them (forgot the brand) and they are rated at 150 Lbs but only has a 1/2 horse motor and draws only 4-5 amps. This runs the compressor just fine off the batteries. I do have a 3500 watt generator/ inverter as a back up, but the inverter does a fine job for a few tires.
