12v air compressors

[MovieDude]

Just looking for a portable unit for topping up my tyres. What minimum psi and flow rate do I need? Seen an Ozito model at Bunnings that puts out 150psi and 35L/min but don't know if that's enough.

A bike foot pump is all you need to pump up your tyres. You don't need an electric unit unless want to inflate 4WD tyres quickly when going off road.

Ok I'll borrow my son's bike pump but I'll need an adaptor.

Think it boils down to how often you think you're going to be needing it... More frequent use, if be buying something which has a storage tank. Or if it's just for emergency then a small unit which will take longer to pump.

It might well be cheaper to go to an auto shop eg Supercheap, Repco etc and pick one up. For light duty, you won't need to worry about thermal cut out so pretty much anything between the $50 - $100 range will do. Just make sure the hose fittings are secure and fit securely on your tyre valves. Pretty much any portable air compressor within that price range will be more than adequate for the tyre pressures you're running. The higher the air flow, the quicker you'll pump your tyres up.

I have a Twin Tongue compressor hard wired in my Troopy. Pumps tyres from 20psi to 38 psi in about 2 minutes. Rated for 57L/min @ 0 psi down to 34L/min @ 60psi. Pumps out about 40L/min @ 40psi. Not sure what the duty cycle is but it can happily air up four 4WD vehicles (16 tyres all up, various sizes from 31" to 35") from 20psi to 40psi one after another without thermal cut out. $1050 bucks installed though.

Also, invest in a good quality tyre pressure gauge (analog or digital, up to you but digital needs batteries which tend to die at the worst time just as you need it).

Good advice thanks.

If you're an RAC Member, Repco currently has a 20% discount storewide too.

Buy one of these Have had 2 of them and they are pretty accurate

3 in 1 Tyre Gauge - Bushranger

You screw it on the valve and it has the ability to lower presures as well.
Autobarn and Repco sell them but abit more than $32 I paid $36 at Anaconda

It would be cheaper just to buy one of these and go to the servo Pump tyres a bit harder and let them down with this to correct level.
Cheap compressors are never real flash and the gauges on them are a lottery as well

I've already got a bunch of Ryobi One bits and pieces so this was just another additional to the toy box:

I use it on bikes, balls, air beds as well as the car/van tyres on the odd occasion I've needed/wanted to. By no means a professional piece of kit, but for my home use it's brilliant.

On a side note, apart from the drills I use all the time, this is probably the most used of all the accessories:

I have a good analogue meter so just looking for a cheap compressor to do the job.

We use one of these SCA 12V Heavy Duty Jump Starter w/Air Compressor – 1100A - Supercheap Auto Australia Battery Jump Starter packs to inflate our Moto Cross bike tyres also for the van as well , whilst a bit more expensive than the one The Hawk posted it can be used to start a flat battery inflate tyres has light and 12v power outlets .

Good tip!! I'll check it out myself. I'm using Staun deflators atm to air down before going on sand, which can be a bit of a pain at times because it can be a bit of a gamble hoping all four are set to deflate to the right pressure. Tyres rolling off the rims in sand is NOT a good experience.

On another note, the on board TPMS in the CC is pretty accurate.

I have to say though, the on board TPMS in the CC is pretty accurate.

Yeah I had 2 sets of Stauns and never used them Sold them on Ebay for a lot more than they cost me.

Screw the Bushranger on, Hold it down soon gets down to right pressure

I have an ARB Twin pump set up in my van for 2 years now, and by far it's the best value for money and it wins on performance too. I've had the Blue Tongue twin and have burned 2 of them within 4 years. The Big Red is more durable than the Blue Tongue by the long shot. Though, if you use it only for top up your tyres a few times per year, the ARB single pump is not much more expensive than the twin pump cheap ones out there and it will probably last you a lifetime.
