I've got a 12v car tyre air inflator that I used to use on my old cars and still use on family members cars.

However, it doesn't work on my C4 Picasso. Whichever 12v socket I connect it to (dash, rear seats or boot) - it won't turn on.
Other 12 items work as normal, such as phone chargers etc.

The air inflator works on family members cars - as I tried to do mine at the same time as another car. It works fine on the other car, but not on mine.


Has anyone else had this issue?
I wonder if the C4P's sockets get slightly less power - so high usage items don't turn on if not enough juice?

All I can offer is that I used to use mine with my engine running. Certainly didn't work without the ignition on. But I guess you have tried with the engine running.

As most Picassos have a tyre inflator instead of a spare, it is unlikely that there is any real issue. Usually the problem with these is that the current draw blows the fuse. I wonder if there is an issue with the plug (not socket) preventing contact.

Thanks for your replies.
Yes I've tried with the engine running as that's usually how mine works.
Still no power when connected to my C4P.
I'll look for a new one. I could do with a nice new digital one with auto turn off.

My one doesn't even fit properly into the 12v sockets. Not too bothered as I have my own compressor.

I've been looking at getting this one;
https://www.amazon.co.uk/Inflator-Compressor-Portable-Electric-Swimming/dp/B0791W6XRQ
Oasser P6 Digital Tyre Inflator with auto stop & flashlight
only £25.99 and has excellent reviews and is very compact.

Looks like a good one. It has the clip on unlike the common screw head which is a pain to release without losing air.

I usually pump the tyre a bit higher than the recommended pressure then slowly release air using a hand held pressure gauge so that it's very accurate.

I think the max current is different for different 12v sockets in the picasso. Away from mine right now but maybe handbook or fuse diagram will help. I think the one in the central cubby allows more current than the ones at the back. Worth checking because accessing fusebox is a pain.

Thanks.
I know my fuse hasn't blown in any, as all of the sockets work with phone chargers - but not with my old tyre inflator (Halfords own).

I'm not too bothered, it's an excuse to get a new one.

Sometimes it's the size of the +ve that stops it going in & making contact
