Portable compressor Options
allright, time to bite the bullet and get one. I used the search but can't seem to find the long discussion several months ago - I assume thats
operator error on the search function.
so I'm thinking ViAir
is there other options I should be looking at.
I find 3 options I am interested in on viAir
The 88 - 20 amps 1.5 cfm 65 bucks
the 300 40 amps, 2.3 cfm 40 amp - 140 bucks
the 400 looks to be the same as the 300, but a nice carry bag? 175 bucks
really not looking for the cheapo Walmart harbor freight options looking for a durable hard worker that I will have for 20 years.

The MV-50 is not pricey ($85) but works well and fills my tires from 15 to 30 psi in 2.5 minutes, each. Just fyi.

my vote
I've had the Viair 400p for many years. The only issue was when I first used it, we aired up eight tires from 20 psi up to 35 psi - on the last tire,
the o-ring just inside the hose (where it connects to the compressor) split. It does get quite warm at that point. Viair replaced the entire hose, and
since we fixed the original hose I now carry a second hose, just in case.

I have used many different 12v compressors through the years. Of all of them, the Viair 400 series has provided the best balance of performance and
cost effectiveness.
I have a Viair 400P that I use for my Xterra and other vehicles and a Viair 400H hard mounted in my jeep.
If you have 33" tires or larger, the 400 series will be a better choice than the 300 series.
The 88P is the least expensive, but isn't really designed for larger tires. It will run very hot before you can finish four tires 31" or larger.
I am no fan of the ubiquitous MV-50 "cheap Chinese compressor." Performance is marginal compared to the Viairs and they tend to suck reed valves and
self destruct.
Here is a link to my hard mounted compressor installation:
https://wranglertjforum.com/threads/how-to-simple-onboard-ai...
The Viair 400P is regularly on sale on Amazon. Input your search into camelcamelcamel.com and you can receive alerts when it reaches your target
price. I paid between $150-160 for mine.

cfm is the number you want to look for
anything below 3 cfm is not worth having for Baja sized tires
20 years?
consider this: none of the compressors have lubrication (pistons, rings etc)
ever tried to run your car engine without oil?
even running it only once a week for 20 minutes you won't get 20 years out of it
so, the bigger the piston of the compressor is - the better
bigger surface, bigger rings, less speed, less wear
higher volume of air in less time
spraying WD40 into the intake before every pump action will make the compressor run for many years
I won't get into the substandard wiring of most compressors
I bought a PUMA 20 years ago, always primed it through the intake, babied the cables, replaced the pressure switch twice - still pumping up big tires
in no time

I've had no issues with my Viair 85P. I did toss in a couple battery clamps in case I ever have problems with the power port connector. I really
like the screw on hose connector versus the lever type.

Another tip for most 12v compressors is to ditch the yellow coiled hose in favor of something with standard fittings that isn't so stiff.
I use a Flexzilla 1/4" x 25' air hose with an open chuck.

4x4abc – what Puma are you using? In your post you liked pumps 3 cfm or more, but the 12 volt Pumas I see available max out at 1.36 cfm.

Many sellers of 12v air compressors advertise the CFM at 0 psi, which is relatively meaningless. The MV-50 is rated at 0 psi, so is the Smittybilt
unit.
The Puma compressor is rated at 2.0 CFM at 40 psi and 1.36 CFM at 90 psi.
The Viair 300 series is rated at 1.48 CFM @ 40 psi and 0.92 CFM @ 90 psi.
The Viair 400 series is rated at 1.75 CFM @ 40 psi and 1.28 CFM @ 90 psi.
The ARB "single" compressor is rated at 2.34 CFM @ 29 psi.
The ARB "dual" compressor is rated at 4.68 CFM @ 29 psi.
YMMV

A Puma is way too big and overkill. You want one that pumps like crazy and fits in your the center console in your truck.
Here is what you want op. Thank me later.

Thanks for all the inputs guys, it's been educational.
so after thinking about it, i'm going to go rouge. I bought one of those rechargable pistol grip units.
https://www.amazon.com/gp/product/B07CTGM2LD/ref=ppx_od_dt_b...
I like the idea of it not requiring the battery hook up, but I can run it that way. plus I really like the portability.
If i was getting a unit for my Land rover - with 33s and rhinorunnin then yeah, I would go ahead and get the ViAir 400. but for my ridgeline and
tribute - I think this is all I need, and alot more convenient, and more useful around the house as well. Plus my wife will not be intimidated by
it, thats always a plus
thanks again for all the info!

Send that thing back asap. Get one that connects to your battery. That think is junk. You don't want junk when you are in the middle of Baja.

Oh my, yes indeed. If it doesn't clip onto the battery, it cannot draw the amps needed for high flow. Plan on taking 6-10 minutes per tire instead of
2-3. I get that you may not want to spend $300 for a pump that is no quicker than the $85 one I mentioned. I also got a Harbor Freight one before the
MV-50, it was also fast (2.5 min per tire), but got very hot and melted the fuse holder.

I agree. Cancel that purchase and get a tool rather than a toy.
If you want something small and relatively inexpensive for passenger car tires try this one for $62.03 on Amazon Prime, 1.47 CFM @ 0 psi/1.15 CFM @ 40
psi:
https://www.amazon.com/Viair-00088-88P-Portable-Compressor/d...
However, even though the 88P would be adequate for smaller passenger car tires, I would still recommend the greater capacity of the Viair 300P for
offroad or Baja duty.

another word on cfm
we don't run our tires at 90 psi - so forget that number
very few of us run 40 psi on pavement, let alone off-road - so forget that number
you want to get quick from 10 to 20
or from 20 to 30
that's where you want your pump to deliver at least 3 cfm
the Puma does 4 cfm @ 20 psi and 3.4 cfm @ 40 psi

If you carry a lot of weight in your truck (ie a camper) you will need more air or your going to heat your tires up on the highway and blow a
sidewall. I need 70 PSI for the highway and lowest I will go for sand is 30 PSI.
A Toyota is a bush go- cart. Lots of fun but you can’t put anything in them.

 well this discussion on professional tools morphed into a discussion of
crap......enter Don Pisto! on our 3rd MF1050 (we suspect what the MF stands for).....we like these little harbor "fright" guys, I swear they pump up
33's as fast as the "tsunami"and they're $25.
don't be like us buy a professional tool from the get-go. if its about bikes go with Larry, cars Harald!
