Is there a decent 12v tire inflator out there?
On my wish list is a compressor which is no big deal, but generators are expensive.
We are trying to come up with the best way to add both of those things to our rig when we can afford it.
In the meantime I thought we could get by with a GOOD 12v, if only to get us enough air to make it to an air station.
I have seen them from $20- $50.

Re: Air
I do not know what you are driving or how much you want to spend but you may want to look into On Board Air (OBA). It uses an added AC compressor or an existing one if you don't need AC. I hope to add one to my bronco some day. I think most parts can be pickup used. Google on board air. There is a lot of information.

Re: Air
I am driving a Ford F-250 Super Duty with an 8' bed with an 11.5' camper.
Thanks I'll check it out.
No way am I forgoing AC though.
I am guessing I will have to sacrifice something from the camper to make room.
If I find something small enough it can ride in the camper and then go into the cab when we are settled.
Most of the places I go have air stations but thanks to all the vandelism I can never depend on them.:confused:

Re: Air
I know a compresor can be added to a bronco or older ford f series trucks without doing away with the AC. Not sure if it will fit a newer F250. Look for Bronco Air it will give you some ideas. I have never done anything with them but it is good looking stuff. Someday.

Re: Air
Onboard air that will pump up tires on your camper without overheating or taking an hour to do starts about $1,000:eek:

Do a search for oasisairsystem.

Re: Air
Check out Kilby Enterprises. I have that in my truck. It is a second mounted York compressor with the pulley attached to the alternator pulley with a belt. Way less than 1000. It mounts under the hood. I just had to move the "coffee can" over a bit to fit it in. You keep your air conditioner compressor.

Re: Air
A decent 12v compressor starts at around $300. Any decent compressor hooks up to the battery not the cigarette lighter.

I did a homemade York on my truck, came out mint!

Re: Air
Thanks guys I now have a place to start.
Wouldn't it be wonderful if those cheap 12v things worked?
It looks like this is going to cost big bucks no matter what.
I like the onboard idea because then I don't have to haul a compressor and a generator around.

Re: Air

check out the Outback extreme portable. It will probably still take around 4-5 minutes a but it is a good unit.

Unfortunatly, large rigs need big tires and big tires need loads of air.

Re: Air
Craftsman has an electric compressor 110v good one about 100 bucks buy a power converter and plug it in:D

Re: Air
Thanks Steve:D
Okay Hammerhead, sounds good. Now can you tell me where I can find a 7 mile extension cord for that electric compressor?
We have an electric one at home.
The idea is to have air when I am on a beach that doesn'r supply air.
Even when they do supply air 75% of the time some fool has broken it.
11,000 pounds is allot to drive with 20 psi in the tires, even for a short distance.
Even if I can fill the tires halfway I will be better off.
5 minutes is nothing!:wow:I'm going to check that one out.

Provides household current from any 12 Volt power source.
Up to 90% efficient. Max Continuous Power: 1200 Watts

Re: Air
Hey we have one of those Jess.:D
It's only 750:uhoh::(. I wonder how that would work.
I never tried hooking it up to the truck battery.
It sure drains the booster fast though:dunno:
I wish that other tax check would get here.:rolleyes:

I run this with a 20 inch tv at the football game for about 3hrs also has an auto battery drain shut off!!

Re: Air
I seriously doubt that any of the cheap inverters will drive a compressor. They may advertise the rating in watts to run it, but i seriously doubt they can handle the surge required to start an electric compressor.

I predict crash and burn at worst, blown fuse on the car or thermal overload on the inverter at best.

Even a DC compressor capable of filling tires in a reasonable amount of time requires around 30-40 amps DC supply. Each and every connection or conversion looses capacity as none of them are 100% efficient.

If it plugs into the cigarette lighter, you won't be happy with it filling the tires on a 2500+ series pickup.

I could be wrong, but I would be shocked.

I wish I had some better news, but being only 1 beach that I go to has air, I have been down this route already.

Engine driven, hard wired DC or tanks of pressurized gas are the only options unless you have a lot of patience and time.
