Air Compressor on generator?

I'm having a heck of a time finding the electrical specs on these things... I can't even find numbers on my Campbell Hausfeld sitting in my garage-

What I'm looking for is a portable model, with at least 2GAL capacity, that my YAMAHA 2400 will run... I've been told compressors tend to draw monster loads on start-up

Any ideas?
Without knowing the motors efficiency coefficient- is there anyway to derive watts/amps from HP?

I don't know if this helps, but the framers who were working on my house used a very large compressor - I'm guessing around 50 gallon. All of my temporary power outlets are 15 Amp and they were able to operate their compressor with no problems.

I just looked at my Porter-Cable 6 gallon pancake compressor and it's listed at 10 amps. That shouldn't be a problem. But if you really need to know, I'll haul out the Yamaha and test it.

Another alternative could be what Jeepers use. Because they deflate their tires for rock crawling some adapt an old auto AC compressor to reinflate the tires. Adapt by mounting the compressor in the engine compartment to run off of a 'fan' belt.

Hi, I have a home model air compressor [2.5 H.P. / 120 Volts / 15.0 Amps] with about a twenty gallon tank and my Yamaha 2400 won't start it. [Yamaha 2400 rated at 16.7 amps max]

Did you ever find what you are looking for? I'm trying to find the same type of compressor as in the last image...a tankless, adjustable output for my airstream. Any recommendations? Thanks.

I ended up buying a tiny 1gallon 'powermate' on sale for $48 from K-Mart. Small enough to fit in trailer trunk. (No specs on the box, "100PSI working pressure" whatever that means, took me 3x as long to blow-out the lines/waterheater). EF2400 didn't flinch at all running it.

I run my 40 and 60 gallon 4 and 5 hp compressors with my 3500w generator, along with circular, miter and table saws. You should be able to run any 2 gal compressor with a 2400. Stay with a name brand like dewalt or porter cable. Some of the less known brands have higher startup loads (I had one).

I'll go out and look at mine and post what they are rated at...

My Dewalt trim compressor (1Gallon) is rated at 1560 watts. (amps x voltage = watts roughly)

You should be okay with any small trim compressor. Just ask if it will run from a 20 amp outlet....

20a outlet at 120v is rated at 2400 watts max....

Look for a compressor with a smaller motor. Bigger the motor the more amps it takes (more watts). Bigger motor means quicker recovery, smaller motor just takes a little longer (runs longer)..my dewalt is .6 hp

Just as some additional info...
My Honda 2000 will run a 2hp Campbell pancake version but WONT run a 2hp Horrible Freight unit that I bought.

Well, It will RUN it but only if ya dump all of the pressure from the tank before you try to fire it up.

I have run my portable 2 gallon CH compressor off my Honda 2000. Eco throttle off.

you'll need a tank if you want to blow out the water lines properly. the pressure regulator isn't exact.
