Hey guys I'm wanting to run on board air for many reasons from truck tires to bike tires. Depending on set up if I run a tank or do continuous I would have other uses also.
My Titan has a 12v outlet in my bed which is weatherproof so I was trying to decide if my little 2 gallon compressor could be bolted to my bed and run off an inverter that would be mounted inside bed as well. The inverter would come in handy also [emoji6]. My compressor claims ma amps of 2.2 so I think I decent inverter could handle that right? If not should I just get a little 12v compressor? Not looking to invest in a arb or anything. Only need light use of air.

There is some extra math involved when taking amps from AC to DC. Assuming your compressor is 2.2 amps at 120v, when you run that through a 12v inverter, it becomes something like 24 amps. I found this website to make the conversions. You might look up how many amps that 12v plug in the bed can take and how many watts your inverter will need to support.

Check out Amazon, there are a lot of 12V air compressor options that should fit any budget. I found a great compressor there that does 1.7CFM, up to 200psi and it is around $100. You could add a tank and have a complete system. Or, look at Viair, they have one for about $100 with tank.
If you have big tires, you need one that has higher CFM.(volume) Any compressor can make 100psi, but it is the volume (CFM) of air that fills the tire. This will be the difference of 2 minutes per tire or 20+ minutes per tire.
Also look at duty cycle, this is how long you can run it, % on time vs. % off time. The higher the better. 100% is ideal, but not always cheap. Cheaper (Low duty cycle) needs to run short times, then left off to cool, or they burn up. 100% duty cycle means you can just keep it running non-stop.
So, a high volume, 100% duty cycle and add a tank and you will be the envy of everyone when you air back up. With the right parts this can be done for under $200-250.
I would add links, but this site does not seem to accept Amazon links.

I've been using a 24V li-po powered compressor for two years now, it fills a 32" tire in under 2 minutes, has pressure control so I can just walk away and no over inflation. I have two other tools that use the same battery, the battery has a 9-12 month self life before needing a top off. I can fill 4 tires maybe 3 or 4 times before the battery is down.
