How to run 12v ARB Air compressor off 240v

Steve

The most cost effective way is to take the items to your car and then pump them up there.

Car air compressors use a lot of power and I doubt that you would be able to find a power Supply that would safely handle 30 plus amps

You need a 240V AC to 12V DC power that can handle the current draw of the compressor. Had a quick scan of the net but couldn't find the actual current draw of the ARB units.

The following gives examples of upto 66A:

800W power supply

Most simple way surely would be a 12 volt battery and charger but you could also use a transformer ??

You could use as someone was saying previously..a 240v - 12v battery charger as a power supply with Anderson plugs so you could connect up to the compressor. I believe Victron have 240v -12v battery charger that can be put into power supply mode via the Victron Connect App for the device..something like this. Victron 240v Battery Charger..you will need to shop around as they start at about $250.00..

You could probably buy a 240V compressor for $150 or less.
I bought one for the OKA for under $100 16 years ago. Changed it for a 12V PX07 10 years ago to save some weight and put the 240V one in the shed. Still going well.

If you’re just doing inflatables then this will do the trick https://www.snowys.com.au/manual-65l-double-action-pump

G'day Steve.
I leave my 12v compressor in the 4wd & like you have items (wheelbarrows, Garden trolleys, hand trolleys, ride on mower etc) to keep aired up around the garden.
I bought the larger Ryobi 18v compressor for all those things & as I have a Ryobi drill I just use that battery.
Even use it to top up the trailer tyres when its parked right up the back of the yard & it handles it no problem.
I am sure whatever brand battery tools you use would have a similar battery compatible unit.
Means that I won't forget to put my 4wd compressor back in the truck when I am done or have to lug a battery around the yard to power it.

What's wrong with an el cheapo foot pump? Buy two for less than $30 and get some exercise as well.

No need to over complicate things.

I'm always being asked to pump up kid's bike tyres, basketballs, soccer balls etc -my own grandies and also the neighbourhood kids. Word got out somehow :-)

I've kept an old AGM crank battery for the purpose and keep it charged with a small Ctek.

If you can get hold of a battery I think that's the way to go. There are other ways like power supplies, but with a 40amp output they will be expensive.

Hi Steve,

The ARB compressor will draw something like 30 Amps or more, so a 240/12volt power supply of that size would cost a couple of hundred dollars.

But an alternative could be to keep the compressor at the car and run a length of air hose from there to the garage.

Thanks for all the suggestions - much appreciated.

x2 for a cheap 240v compressor, far more convenient.

A very cheap 12V power supply can be made using the computer PSU's. I have just finished making up a dual 12V to run 2 fridges in the back of the car when I have access to 240V. The PSU came out of an old PC that I was no longer using and has 2 x +12VDC supplies at 17A each, if these are connected in parallel you should get double the current.

Here is one on eBay that has 2 x +12V outputs at 34A each - 850W ATX Cooler EXTREME Power Supply Silent Fan PSU Desktop Computer PC Gaming and is only AU $76.50 each.

I agree with other that a cheap 240VAC compressor would be easier but the above is a reasonably cheap option.
