Figure worst case scenario, 12 amps @ 110 volts (anything more and it would pop a breaker), would be 1320 watts. So a 2000 watt constant draw converter would do the job.

Downside to this is the converter itself has losses, plus 12 amps @ 110 volts = 110 amps @ 12 volts even in a perfect world. That is worst case of course, but you're taking about a damn big load on your battery all the same. You're much better off getting a motor designed to run at 12vdc.

One possibly solution I've been looking at is getting a replacement winch motor (4.5hp at 12vdc), and adapting a York to it. As far as I can tell, this is exactly what Kilby is selling as his HP3000 electric compressor:



This would be about $120 for the motor and $50 for a junkyard York, plus whatever it might take to connect them together. I'm seriously examining this option

I've decided to go with a Co2 system for now. Cheaper and I don't feel like spedning the time to hunt down parts at salvage and junk yards. If anyone finds everything and puts it all together I'd love to see pics though!

 

Yeah, I'm waiting to see where people mount their compressors and tanks too. I have the QuickAir II (Portable) with the tank install kit, but I'm not sure where to mount it yet. For the time being, I modified the portable version to use a quick fill gauge (compressor stops when line pressure goes too high). Here's what it looks like:

This just poped into my head. Has anyone tried to convert the rear storage bin into a auxilary air tank? It's probably about the same as a 2.5-3 gallon tank???

 

anyone using this compressor from harbor freight. looking to see if its worthy

 

That is where my air tank is at. A 2.5 gallon barely fits in there, but the top of the tank is about an 1" above the floor board, so you will not be able to use the door. I am going to try to build a cover for it though.

BTW I have the VIAIR Constant duty on board air kit which has everything thing you need, compressor, tank, all fittings, hoses etc. I have found them online for about $370 shipped

 

Quick Air 2 or 3 is a good choice. I'm currently using a portable QA 3. I might take it out of the box...hard mount & wire it in the cargo area soon. Power Tanks are amazing. Had one of those in my TJ.

 

I think it was "hemi" wasnt it...

 

Yes, I have this unit. It was well worth the money (I think I got mine on sale for about $50). I haven't tried it on my new 35's but it would air up a 33" tire from 12lbs to 30lbs in about 2 min. I have heard of others having issues with them. Other than the guage that comes with it doesn't work worth a crap, mine has worked flawlessly!

 

im sure HF offers a warrenty
