Airing- up faster?

I'm outfitting my new-to-me 2014 Taco for some backcountry adventures and it's time to buy portable air compressor for airing-down and airing-up. For years, I've used a 12V compressor with my 96 Taco, which worked fine, but it occurs to me that I could use the power outlet / invertor in my 2nd gen to power a new portable compressor.

My goal is to be able to air up more quickly than I am now, plus it may be *slightly* more convenient to use a power plug than the leads off my battery. So would a small compressor running 110V off the Taco power plug inflate my tires more quickly? Or would the difference be negligible? Thanks in advance!

 

Without knowing the output of all the compressors involved impossible to know.

My guess is not enough difference to make a major difference.

Go to a extra tank use 1/2"air hose and fittings your still are reducing speed through the air chuck and valve stem.

If you really want to know the equations can be found to do the math and find out the best possible speed forgiven volume of air per tire.

 

I like the portable ARB compressors. It does require you to hook up to your battery, though.

 

I looked at the airing up tires one of three ways. Pick two.

Reliable
Convenient
Cheap

Ultimately, on board mounted ARB twin with outlets front and rear was the ticket.

Not cheap, but reliable and hella convenient.

 

Unfortunately, the 400w inverter isn't going to power any sort of decent compressor. All the large volume tire compressors are 12v. I run a modified Napa Maxi Trac dual compressor with a homemade 4 way inflator and can air 4 33s from 14 psi to 34 psi in about 2 and a half minutes.

 

Any chance you could show a video of a four way fill in 2.5 mins?

 

Not at this moment as I have the compressor torn down for an OBA install. For what its worth, I have aired up multiple vehicles at +9000' elevation back to back in that sub 3 minute window.

 

Reason I ask, is that I can usually air my 4 33's from 12 psi, to 34 in about 10 mins filling two at a time. Having to move my inflation system from front to rear between sets. That usually is only a few mins to do.

 

I run a small compressor off my inverter plug. I think it's a Goodyear brand compressor about the same size and output as the cheapo battery ones but way more convenient to use the inverter with. Airs up from low to "get me home" in about forever for 4-tires. But all my friends are cheap too and we're all airing up in about forever.

 

The Power Tank has always been the fastest from my gatherings.

The ARB Twin and the Napa Twin are similar in output, so I am genuinely interested in seeing how well your system works.

On the flipside, I am not usually in much of a hurry airing up/down as I am being less motivated to pull out and manually connect the compressor to the battery, run it and have to stow it again.

 

Airing down and having a way to air back up is more important than the cost of or the speed to do so. Many folks chance a trail without success because they don't have a way air back up.

That and tires at road pressures on the trail are obnoxious and cause trail damage.

 

I have a pretty decent Viair (450P) but since I bought a Milwaukee M18 compressor I've found myself reaching for it more often than not. It is decently fast but I have yet to use it to fully air up my 265/75/16s. I waited until it was on sale before I pulled the trigger. If you already have M18 tools it is a good addition:

I also have a home-brew CO2 tank similar to a Powertank. It is definitely fast but since you have to refill the tank it is not as convenient as a compressor.

 

The 4way definitely speeds things up and I use it to inflate and deflate. Its a little clumsy as it doesn't break down but I used 1/4" tubing as opposed to a lot of the ones for sale out there that use 3/8" which is overkill in my opinion.

Its hard to beat the performance of the power tank, although in start to finish race between a buddy of mine with the powertank(single hose) and me with the maxitrac(4way) I had him by about a minute.

 

As nice as under 3 min for all four sounds, I'm typically not in a rush and therefore haven't put the $$ into a twin or the ability to do 4 at once.

 

I totally get that. I really enjoy making stuff and after seeing the price tag of the ones you can purchase I decided that I would save $3 and make my own.....

 

Nothing wrong with that logic at all.

Just having the ability to air up is all that matters. The extra time it takes per tire will actually give a guy time to inspect various things like fluids, tread damage, trail scratches, or make a snack, play fetch with the dog(s), or enjoy the current view around you, etc.

We go off road to get away from the daily rat race, so air up speed isn't necessarily the prime focus.

 

If nothing else, the Milwauke is a good solid backup unit.

 

If you really want to inflate quickly, you're going to be disappointed by most 12v compressors (when compared to a large shop unit).
Anything you can power with the rear 110v outlet is going to be worse.

As far as something on our trucks, bite the bullet and get the best:

Like others have said, I doubt that outlet will help. If I were looking for portable and speed I would give this one a look: https://morrflate.com/shop/air-sour...-tensix-portable-12v-off-road-air-compressor/

 

Not liking the rated 50% duty cycle filling 4 tires at a time. And worse if filling one tire at a time.

I believe my ARB Twin is 100% no matter how many tires I fill in a row or at once.
