Good 12-Volt Air Pump/Tire inflator?

[Rene Michaels]

But there is a 12 power source right behind where you mounted the compressor. Why did you run power all the way to the battery?

From the little I've read so far, the cigarette lighter plug won't handle the 25+ amperage of a good compressor and it will blow fuses. Much safer to plug it into the truck battery.

If you want a cigarette lighter model, I can recommend this one. There are better pumps available, but I've seen nothing to touch this one for the price (around $50-60). Powerful, and a long cord, and a good-sized hose, with a QD fitting.

It's rated at 15 amps, which is about the limit for a cigarette lighter connection. If you want more power, you have to use a straight battery connection. I have a few of these (kids' vehicles), and the only problem I've had is the carrying bag hardware is a little flimsy, and the polyurethane hose on two of them disintegrated after a few years. Not sure if that has to do with storage conditions, or something else, but this pump is solidly built. The pump is very powerful, with good flow, and I've used it to air up a full size tire from completely flat in about three minutes. It gets a little hot, but it has a lot of fins on the cylinder, and it's mostly metal. There's a rubber bumper on the pressure gauge, and room in the bag for a tire plug kit and a pair of pliers, etc.

The Viair model mentioned looks pretty good, too, but they are a tad pricier.

Because the compressor will use up to 40 amps and the power source by the bed is rated about 20 at max.

Okay. 12V @ 20 amps is quite a bit. I'm betting that compressor will air the tires up fast.

I use my Dewalt Flexvolt Portable Compressor. Fill the tank when you air down and it doesnt take long at all to fill em back up.

It is rated to fill a 37 inch tire from 0 to 30ish(my guess since ARB didnt specify) in 2 minutes.

OoppS...Fixed it. Guess I didn't hold down the command c keys hard enough. Or I was trying to make you spend even more money. ?

You've got plenty of money. Here's Brandon out in his back deck while he thought no one was around. ?

Where do you find all that money!!!

Didn't you get all your stimulus checks? ?

I have a Viair 88 that is popular choice. It connects to the battery terminals, which I would recommend over a plug in type. I had one of the plug in types once and it would blow the fuse for the 12 volt outlet. Plus they can overheat and are slower. A connection to the battery is best. This one will do up to a 33” tire

I have their 300P.

Yup, I carry a 20 foot extension cord with me and pass the pump through the cab to get to both sides.

Are you saying you run your air compressor off of the 120v 400W outlet in the back seat? I'm calling BS if you are.

You have 400W? Mine's only 150W...
150 Watts at 120VAC is 1.25 Amps of input current.
This is equivalent to 12.5 Amps output current at 12 VDC (ignoring conversion losses).
That could run a decent compressor, but not a great compressor.
I have a Masterflow MF-1040 compressor, which has a 15 Amp fuse, and it does pretty good.
Never measured the current, but it did pop a 10 Amp circuit once.

One of my planned upgrades is a decent 120VAC, 15 Amp circuit in the rear.
Haven't decided exact location yet. (This is 1800 Watts, btw)

Lol so here is what I did!! I got the Ford Performance portable kit!! I also decided to make it a full on-board kit because thats the kind of person I am!! Wich compressor does Ford use? They use the ARB single compressor that is reated to fully inflate a 37 inch tire in 2 minutes. How well does it work? Verry well!! I think I can inflate all my tires between 5-10 minutes from 18 to 30 psi. Here are some pictures of my little setup

This is pretty awesome.

So, you want to have a 120v, 15amp circuit? That's a lot of juice at 12v
