Or you can do this without needing to draw power from the vehicle. Just another option.



There are also portable compressors that can be plugged directly into the 120V outlet. Lowe's Kobalt has one: https://www.protoolreviews.com/kobalt-120-volt-tire-inflator/

And there are other 4-tire inflation kits out there besides Morrflate. They do have very nice hardware, I'll give them that, like the closed-air chucks that are slightly smaller than the standard brass ones. Some wheel designs do not provide enough clearance for the standard ones (like the factory 20" "staples" style). And they can be bought separately from Morrflate. I chose Speedflate's kit because of their coiled hoses. They stay off the ground, no chance of tripping or being run over. And it packs away clean and fast in a standard sized camping stuff sack. And having hoses that stay off the ground is nice when you go in the desert, where just about every plant has thorns.
Interesting! I guess the only downside would be taking up a bit more space, and refilling, but it sounds like he’s gotten over 17 cycles of airing up and down and still hasn’t emptied the tank.

I mainly went with the Morrflate because they were one of the few companies that responded when I told them what I was trying to do, so far so good, will be interested to see how they hold up being drug on the ground.

There was an extensive thread on the 120v compressors which was really informative, but overall they just don’t push the air I was looking for
Maybe I'll use deco gas. Trimix is way pricey these days. 🤔
OOFFFFFFGAAAAAASSSS!!! 😂

I have the built-in compressor, and it's great! But, that being said this seems like a lot of extra work. Why are you bothering to deal with 12V? Why not just buy a 120V compressor and plug it in?

Couldn't you just clip to the screws on the leads directly too? this seems a little... zappy... if you stand too close and gesticulate while talking. ;)
That was my thought at first glance. Seem like an over-engineered solution that could lead to more problems.

I wish! The alligator clips are too big to clip to the screws. Too close together unfortunately. And any day you can use the words zappy and gesticulation in the same sentence, thats a good day. Thanks for the laugh! 😀

What? Having bare electrified metal sticking out, super close to each other? What could possibly go wrong?!?! 😂

Good question! I actually have a pancake air compressor that I use all the time, works great. The problem is size, portability, and airflow. What I went with fits easily in the frunk, and is tankless so I don’t have to wait for the tank to refill once emptied. Wandering the threads here I actually found a tankless 120v compressor that plugs in, which would have been perfect, but they no longer make it.

Power tanks work well too and can be refilled at welding supply houses. I scuba dive so I've got an adpater, I never use, to also air up. I'm just not keen on adding Nitrox to my tires.
You use the geezer gas too?

It's optional now.
My question is.... If the onboard compressor option is $120 and the third party compressor with accessories is roughly $500.... Why wouldn't you just get the onboard option???

The onboard compressor is an $800 option.

My bad, thank you for the correction. Still, if you are paying for a 80-110k truck/SUV..... Spending an extra $300 for the convenience and clean install of a compressor 🤷🏻...... I'll take that for sure

In my case it was “on the floor” to qualify for as many rebates as possible. Otherwise would have gone with the onboard option. Although have heard mixed reviews about operation and hose storage/use.
