Slime Truck Spair Air Compressor
- Thread starter ak_cowboy
- Start date
It seems built as strongly as I expected for $50. The housing is steel, but the filter cap and ends are plastic. It comes with nine feet of power cord and about a foot of air hose attached to the compressor. Probably another 10 feet of hose is included to help reach the back corner. I did not use the cigarette lighter plug since I heard this can pull over 30amp at load and didn't want to blow a fuse. Instead, I used the included battery clamp adapters.
The included LED light is a nice thought, but I have never seen such dismal light from any LEDs. It might help you find your tire at night, but you're better off using your phone if you actually need to see anything.
I let all of the air out of one of the 225/70R16 tires on our WJ with the supplied valve stem removal key (Nice!) and plugged it all in.
0 --->40 psi took 9 minutes total. Here's the breakdown.
2:00=10psi
3:00=17psi
4:30=24psi
6:00=30psi
7:00=34psi
9:00=40psi
I'm a little disappointed that it took so long, since other reviews were getting results closer to 2 minutes. But as long as this one doesn't burn up, I"ll be happy to have it in the back for emergency use only.

It's not bad for an emergency use compressor. For extended use, I'd recommend removing the "cooling fins" - the 4 screws hold it on.
If you look close, you'll see the fins are nothing but a cosmetic plastic shield. The actual compressor cylinder and head are bare metal underneath, with no real cooling. The plastic shroud would make cooling worse.
I had the twin cylinder model, and it burned up after airing up 4 32" on my LC about 3 or 4 times total. I now use a Puma.

That's my fear. Running it for a few minutes at a time probably isn't so bad, it's those long constant runs that kill the compressors.
And assuming you're just airing up tires after a trail from 15-40psi you're looking at 6-7 minutes x4 for about 24-28 minutes to air up for the drive home. A half hour of constant running is going to abuse even high quality compressors so you'll probably have to add in breaks to let the compressor cool. Spending 45 minutes on the side of the trail doing nothing but airing up isn't how I want to be spending the evening.

Sounds good for emergency use, but if you are airing down often, a good compressor is crucial. I also have a Viair 300p. It airs up my 35 in tires from 20psi to 60psi rear and 50psi front with ease. I have never timed it, but I use it all the time and have never had it shut down because of duty cycle.

That's why in the future I'm sticking with 100% duty cycle compressors. With the Puma, not only does it air up faster per tire, but also keeps running between tires (1.5 gal tank), so time is not "wasted".
Companies also fudge duty cycle ratings. A compressor with no cooling fins or fake fins should be 10 - 15%, using Viair as a standard. But Smittybilt claims 66% (40 minutes), which is impossible without severely shortening lifespan.
