I looked at all the options (12V and 120V) and ended up getting a Porter Cable form Lowes. I figure I am never without a generator so no power issues, and it was on sale.

Porter-Cable CMB15

Porter-Cable CMB15 has worked great for me. Both for tire inflation and other jobs where a small compressor comes in handy

Milwaukee 12v inflator

I just got the Milwaukee 2475-20 inflator, which has a digital display of the pressure set. It uses the M12 lithium battery that my other Milwaukee tools use.

I, too just picked up the Porter-Cable $99 deal from Lowes, but dang, is it ever LOUD! I will have to wait until everyone in the park, (and the surrounding county) is awake before I use it. This sucker could wake the dead!

15 amp is the max surge at startup. But 15 amps of 120vac says that the inverter needs to source 12vdc at 175 amps...approx 2200 watts for surge. Most 2000 watt inverters have two ratings on them. Normal running watts and a surge wattage that is usually double the running wattage.

I had a 12V oilless which I wore out pumping 80 lbs. So I got a 1hp Craftsman, oil pump, cylinder tank about 20-24" long. I think it runs on about 1100W. But it will take twice the watts to start it. I had 2 12V batteries and a 2000W Napa inverter. It wouldn't start it. I exchanged the inverter for a 3000W. It would start and run OK but would continually sound a whistling alarm with an error code that indicated more was being drawn from the batteries than was being replaced. I replaced the 2 batteries with 2 Interestate 12V large dry cell batteries and runs OK now with no alarm. It airs my G114's to 125lbs. Tank pressure has to get down to 85-90 lbs before compressor kicks in. So when I air a tire, I first release air from the tank till the compressor kicks in, then I connect the hose to the valve stem and let it air until compressor shuts off. I believe the compressor cost $99.00. It starts harder in cold weather. I have opened the tank valve to get it to start in cold. It always runs on 110V regardless of temp. The cables from the batteries to the inverter cannot be longer than 6 feet.

We carry a craftsman upright 110v air compressor which has adjustable regulator and holds 120psi 24/7. Rarely leaks down. Has come in handy assisting fellow rv'er with inflating low spare. (Remember to check them!) Even operates on our 1500w inverter on two 6vdc battery.

Makita

I did a lot of research and bought this piston model to reach pressure fast. Small enough for under storage

Okay looking at VIAIR they are very proud of their compressors. I do not have a generator, but I do have a 2000W Inverter because of my Res Refrigerator. The 1.5 Horse compressor, that i currently own, draws too much of a surge at start up. I Also think the 1 HP compressors are cutting it a bit close.

Does anyone have experience with the following 2 compressors?

I have 3 tires leaking at the valve stem on TV. I am getting them fixed, but it has me thinking about carrying onboard air.

I sent the VIAIR back to the manufacturer. It wasn't a year old and for what I paid I felt it should have lasted a year at least. They found the reed valve was broken. VIAIR replaced the valve and are sending it back to me - no charge. We will see!


Will keep both the Porter and the VIAIR as a backup.
