Wouldn't really consider this a 'home mechanics' scenario but couldn't find any other section of PH where it seemed appropriate to ask questions about everyday car essentials.

I've various 12v pumps, mostly just small, inexpensive ones that sit in the boot of the cars and one pretty good one that lives on the shelf in the garage. But I've never found one where I felt the gauge was remotely accurate. For being comfortable that the tyres were at the pressures that I want I have always relied on an old foot pump.

I don't want a cordless pump. It's just another Lithium battery to remember to keep charged and to eventually have to replace. I've also noticed that more of the cars don't have cigarette points so I'm connecting the electric pump up to the mains anyway. The logical purchase is a 240v inflator that will just last and last bit has an accurate digital preset for inflating each tyre to the exact pressure desired.

The days of relying on a brand to define quality are gone. Price certainly doesn't any more and reviews are normally faked or written by cabbages so it is to PH, the final common sense resource to ask if anyone has experience of an inexpensive, accurate, durable 240v inflator or if there is a past master worth seeking out in Ebay?

I know you say no batteries, but the Makita 18v pump uses the LXT batteries which fit their other kit. So much less faff than a wired pump.

Hi Bill. I don't have any of their other lot not envisage doing so. For me a mains option is going to be easier. I've power in each of the parking bays of the barn and I don't want the faff of charging bases and batteries.

The key is being able to set a pressure and for the pump to put the tyre there within an acceptable tolerance. With everything being ultra low profile these days I'm finding more cars are susceptible to pressures. It was fine using the foot pump on just one car but when it's all cars you start considering other options. biggrin

thumbup Make sure you swap legs!

I'd have to find and run an extension lead, and have already gone over to Makita for their garden kit so it's a no-brainer.

Yup. I can see the logic. I'm several years away from making that move as all the garden equipment is old petrol stuff that still works perfectly well.

I have a small mains powered compressor with a 6l tank and it is great for tyres.
When it dies it will likely be replaced with a makita cordless inflator.

12v cigarette lighter Ring inflators are pretty accurate (I have a seperate guage and spot checked a few times), I can run mine off my battery jump starting kit so perfect for blowing up tyres anywhere and no need for the car running etc

I wondered whether the solution was something like the 6L draper compressor and then a high quality push on lead?

I ended up buying a cheap Draper hand held thing just to see if it was up to the job. Seems pretty simple and just topped up 4 cars very easily. Seems a good little thing. Durability being the real test though.

I know you said you didn't want a Wireless one but the Milwakee wireless one is really good.

Just invest in a decent pressure gauge.

This is what I was thinking, too. A stand-alone gauge is usually better than the readings on pumps, in my experience.

Obviously you to-and-fro between the two, but I tend to aim high then let some out.

This. I have an ancient air compressor and keep a digital Ring pressure gauge in the glove box and check the tyres every couple of weeks. I had a slow puncture recently an found that my compressor will show around 40psi when the Digi gauge shows 30psi

This is what I used to do. Over inflate with a crappy pump and then use a quality gauge to set it down to what I wanted. I had a lovely mechanical one but it got stolen and I bought a rather nice digital one but it ate batteries so I retired it.

I have one of these, recommend by auto express when they did a group test a while ago

Agree.


The one on the left is from an argon regulator. This is my check gauge. The right hand is for inflation and came with a set for a compressor.
Within a PSI or two.


You can buy oil filled gauges off eBay which are intended for industrial use and have certs to go with them. Unless you run race cars it's OTT.

The main thing is to be able to read the gauge rather than have a small dial that goes up to 100 psi.

Ibe been pondering this: https://www.competitionsupplies.com/analogue-tyre-...

Trying to find one that doesn't look quite so much like an Essex sex toy product.

One of the problems today is that quality is impossible to gauge online where pricing and reviews are generally worthless and misleading.

Look for ASME certification or BS EN equivalent: https://www.instrumart.com/pages/539/pressure-gaug...

I had a similar requirement and ended up with a massive old compressor from eBay that looks like a U-boat and a forecourt grade tyre inflator attachment.

Overkill perhaps, but it opens up the wonderful world of air tools

i've got several Ring cigar pumps and they're all pretty accurate. that said i still use a separate gauge that costs more than the pump! add in a Roypow 10A 240v -12v converter and job done.
cheap, lightweight solution that still leaves the Ring in the car for emergencies.
