Napa Maxi Trac Heavy Duty 12V Air Compressor

[newracer]

This compressor is getting great reviews. If you need a compressor definitely check this one out. Only downside is it does not have any warranty.

I just ordered it, $115 delivered is a great price! My two other compressors are getting old, and I use them pretty often and it takes at least 5 minutes per tire so this will hopefully save me some ‘airing up’ time in 2022!

thanks for the tip!

Someone on the g-wagen forums tried it as well and was very impressed, especially for the price.

I'm hopefully getting one for Christmas. I got a hose and air chalk as two of my other gifts, so I just need the compressor to have my OBA. :)

There is a video where they air up a 38" tire from 0 psi to 25 psi in about a minute, should save you some time.

I'd be very interested to learn how much current it draws.

[RockyMtRebel]

Received it quickly and used it for the first time yesterday. Aired each of my 35x12.5/17’s from 15 to 35. Took 2 minutes per tire, minus screwing and unscrewing the air hose. Definitely faster than my previous pumps, I’m a happy customer for sure. The product is heavy duty and the air hose is much longer than my previous hoses also, another plus on this unit!

[Steve-O]

Alright I'm buying one of these

[Jim]

I'd be very interested to learn how much current it draws.

Reading from specs printed on the side of the box, this video says "Maximum Current of 90 amps".

That is a lot of amps.

[Jim]

Yep - that's a lot. I'd like to know how close to that is the running amps. I went to do a bit of searching...

This vid, which talks about the ARB dual, says "Max amp draw was 68 amps". This sounds like an in-use / just measured number.

https://youtu.be/oceVHPxtWyE?t=1475

Next up in that video... what I take as a generic dual-piston (which I'd put the Napa product into that generic group) he said it "drew 89 amps".

So, perhaps the "Max" rating is close to the "working" rating.

Another generic was 83 amps

My Viair 400P has a 50a fuse.

While we are on the topic, I just came across this brand from this 4x4 podcast I listened to, one of their sponsors... and I think I'm gonna get it

I just got my Napa compressor in... Plugged it into my Lithium 12v battery (the BMS shows amperage) and it draws 58 amps discharging thru the 2' open hose! I thought 90A was nuts but I believe it might just draw 90 under load...

I connected the supplied hose with pressure gauge and the amps shot up to 80 and shut off (my BMS is limited to 80 amps.) The load is the screw on chuck restriction and the added hose length.
Probably draws well over 100amps under load.

My lithium battery probably holds voltage better than a lead acid car battery, so I imaging the amps on a lead acid would be less. I don't have a good way of measuring high amps though.


It is pushing some serious air at zero pressure though!

[RockyMtRebel]

Sorry to be the dumb guy in the classroom, but what does this all mean in the real world? I understand 90 amps is high but what consequences am I flirting with? Is it BAD for my Jeep that it pulls 90 or more amps? I definitely don't want to fry my electronics in my brand new Jeep. I use the alligator clips on my battery in the Jeep with the engine running while airing back up...... am I doing something that could damage my Jeep?

It won't damage anything. 90A is high but a modern vehicle can keep up with that pretty well. It might be a bit much for an older vehicle with a less capable alternator. But as long as you're clipped to the main battery you should be good.

[Jim]

Correct - nothing to see here. Keep the engine running is my recommendation.

If there was any significant concern, we would give more attention to winch amp draw (200 to 400+ amp range - though typically for a shorter duration than 12 minutes).

[speedkills]

I think those are all the same unit. They started coming out about 6 months ago as I recall, all similar price and specs.

that’s the same compressor as the Napa, but TWICE the cost!

[TDash]

No I'm not talking about their compressor I'm talking about their hose system, it will work with any compressor including the Napa one to fill all 4 tires are once conveniently

Just picked one up on NAPA's website, 20% off using promo code "20OFF". Code is good through tomorrow I think

[flashboiler]

Finally played with my Napa compressor a bit. Ran it hooked to one tire and the pressure gauge showed 75psi during inflation (tire was at 25). Then I rigged up a dual tire inflator (at the same time) and the hose pressure dropped to 40psi. (Takeaway: there is a lot of pressure drop in a schrader tire valve)

I dropped both front tires to 10psi and timed the air up to 25psi. 2 minutes to air up both fronts. Pretty impressive! (37" tires)

[Jim]

Hmmm... Interesting stat.

It makes me consider how I might fill two tires at the same time (both fronts or both backs) with minimal hose hassle so that I could shave 5 minutes - because that time is oh so important - LOL.

[Steve-O]

Yea I found that the tire garage that came attached is pretty useless

[newracer]

If they ever come back in stock I am going to pick one up. I'll still use CO2 most of the time but it will be nice to have a good backup.
