Which would likely see blown fuses - I would hope that this pump draws a bit more than 5a!
Pah; after my Ring compressor giving up after a good bit of use, I got a T-Max which I keep in the vehicle (ok, it's a van, but has rear seats and same length as a longer estate.) (Pulls about 45A - so definitely running this from a dinky mains adaptor... but will seat beads in most cases!)

How can you say that? You have no idea what the resistance is.

How can you say that. YOU have no idea whether or not I have an idea what the resistance is.
:wink:
As it goes; I did. From using similar pumps and having them blow a 5a fuse; gives a good guide.
Further, this seems to be the exact same item that is listed at 15a here: ebay.com/itm…448 I'd be a bit sceptical it was that much, but wouldn't be surprised if it was over 5a if it's a half decent one. Typically the lighter socket is fused between 10A and 20A I believe - so it'd be nice if it was under 10 for a continuous draw... it's possible the 15a figure is a start-up power when already pressurised.

Not a bad shout! But I’d be hoping that a mains powered compressor could be slightly larger and more powerful (without being as large as your usual very expensive workshop compressor) - I’m looking for something in between. An adapter could be a very good solution though to at least run the compressor I already have from the mains, so thank you!

devils_advicateabove has very helpfully shown that it IS a bad idea! Certainly in this case they will draw way more than the 5A the 12v transformer will provide.
You could make a transformer up from an old PC power supply that would provide 20A, but probably not worth the effort.
Typically this sort of pumps are designed for vehicle use so have DC motors - that way it makes a lot more sense to power from a native DC source than transform a good number of watts down to 12v DC.
There are a few options for smaller AC pumps, but for the portability in a vehicle aspect, I prefer to stick to DC. As above; if you've got the cash and space the T-Max Adventurer will happily inflate tyres very quickly compared to something like this.

Yes very true. I should have said interesting idea :raised_hand: just hadn’t considered an adapter before. I think something along the lines of this is what I am after (the t-max does look good though):
100PSI Multi-functional Household 240V AC Electric Air Pump /Air Compressor for Car Tyres and Heavy Duty Tyre Inflator to the Ball amazon.co.uk/dp/…57K
The one you linked to I'd worry wouldn't be that great.
If you do have the space, for £20 more you could get an Aldi 25ltr mains air compressor. Ok, for tyres you do have to wait for it to get some pressure up - but then it's much more powerful, so possibly quicker in some cicumstances for tyres anyway.

I tried that combo today, then realised the transformer is rated to 5 amps and the pump at 9 amps. Adaptor will be going back to Halfords. The search for a bigger transformer will commence. Thanks anyway.

Ah never mind. -g- did point that possibility out. Good luck in your search.

Never mind the price, HOT for reliability; I have had mine for twice as long as my last THREE tyre pumps, and it still works perfectly.
My only criticism, is the air hose from the pump is a bit short for larger wheels.

Love lidl power tools, although I've purchased 3 of these for various family members and rocker switch broken on all 3 of them.
And I must say it's worth the extra money. Detachable air hose, detachable power cable and quietest pump I've owned/seen.
Body is plastic, I would have preferred metal, although the rubber surround really dampens the sound and vibrations.

I've had the same generic one, but from Maplins. It eventually vibrated off, it's rubber feet, the cover for the rotating part and then stopped working.
They're ok for emergencies, but the ring ones from Tesco are much better quality and pack away neatly.

Had one in the van for a couple of years and it's saved me a few times

Yep, rocker switch broke on mine too. Didn't have the receipt........ Sounds like a common problem.

They all still function but very temperamental.
I've found the ring 630 to be better.
