Hi
I have a 12v socket in the rear of the van which I use for charging the phone.
It has worked fine for 5 years but has now decided to pack up.
The feed to the socket is fine. I have changed the socket for another.
The old saying works fine elsewhere.
The 12v plug that the phone USB goes into is fine elsewhere but won’t work in this socket.
What else could be wrong? I am flumoxed!!
Regards
 
Time to go modern with these, your ph is 5v and these convert from 12 to 5, take your pick on ebay.

I would definately also try a new lead.
It makes no sense but sometimes a lead can work in one and not another and you get a situation where only certain combos of lead and sockets work together but either are ok with a different socket or lead.
I've had that situation and it does your head in trying to work out what is going on, but life is too short to actually find the reason behind it when you can get a new lead and/or socket for little money.
 
Back to basics.... what is the DC voltage across the terminals of the 12v socket?

Is it possible that socket is wired to a non permanent supply (e,g ignition / reverse)

Is there an in line fuse.

Are you using the same wire to connect your phone? Some wire are data only.

Not clear if you are talking about a 12v socket or a 5v socket, photo please,
 
Thanks for that.

The socket is spurred to a previous one.

The socket you have shown is 12v DC input and using technical magic it changes thie to 5v on the output side.

You say that the socket is 13,4 volts DC across the input terminals so there are 3 possibilities,

a) The socket is broken and isn't outputting 5v
Get 5v usb voltage tester (under £5)

b) The wire is broken or is data only
Try again using a wire that you know charges a device.

c) The device (phone) is broken,

Good luck.

I could try this.

b) The wire is broken or is data only
Try again using a wire that you know charges a device.

I have done this but no change.

c) The device (phone) is broken,

The device is not broken as it works in other sockets as does the USB plug that the iPhone plugs into.
 
Does the voltage still stay above 12v when you measure across the terminals at the rear of the socket and your phone is plugged in? If the voltage drops away you have what's referred to as a 'ghost voltage' it's caused by having a poor connection somewhere in either line, usually a mechanical connection like a fuse.
Multimeters take virtually no current whatsoever and don't cause a voltage drop across the resistance of the poor connection.

Problem is the dash is very thick in places and for camera and speed units there was the only place it could be fitted, all other rear usb and things are nice fit, i can control all the stuff from a switch bank beside the wheel when driving, some of the switches i had to make cover plates and mount hiding large holes cut by the van builders and the last clampet i bought the van from after he gave up but managed to fook every corner inside it, thing is it works now and tidied up somewhat.

Post 10 mentions iPhone....I've vague recollections of iPhones being very fussy as to what cables they will charge from, presumably due to voltage drops under load, probably the slightly dodgy connection mentioned by Merl is the root cause , either run a new wire right the way from fuse board with no joins or charge the phone on a socket it likes. Don't forget it could be a dodgy earth wire to the socket

Different brands of phone can also affect the charging, especially since the 'fast charging'/battery protection 'enhancement' some 2-3 years ago. Elaine had a Samsung Galaxy S22 and it would charge quite happily on the USBs you installed, David; but Google started the fast charging/battery protection with the Pixel 7 Pro, and my phone would refuse to charge using the same cable and socket, albeit, I could sometimes get it to work by jiggling connections around, standing on one leg and pointing my index finger towards the transmitter etc - utter nonsense!

It’s not that the phone isn’t charging or a cable is bad. The socket intermittently stops giving out power although the power is there!
