12v Outlet Drain?

[teamshaw]

Hi

I've got a 2007 Polo GTI and have a iPhone charger that I'd like to leave in the 12v outlet all the time.

As the 12v socket stays on even when the ignition is off, does anyone know what the power drain from the charger would be if I didn't have a phone in it? Does the Polo cut the power to the socket before the battery is completely drained?

Cheers

Charger as in cable? Open circuit = no power.

There's a little LED that indicates that it's getting power from the outlet. But that wouldn't drain much would it?

You could leave it in for weeks and it would be OK mate.

Probably the same amount of drain as it takes to power the LCD odometer. In other words, not nearly enough to be any concern.

Why does the 12V outlet stay on when the cars off, is the golf the same?

Stoney!

The power drain could be 20-35mA if it was only LED on, but there is also the charging circuit for your phone. But regardless, it is unlikely to discharge the battery that is in a good condition if you leave it connected just over the weekend.

Are you sure of this? The socket in my car definitely does not stay on with the ignition off.

Yes my Golf is the same. I use mine for the fridge when coming home from the shops.
I live in the Adelaide hills, some distance from the supermarket. I can call in to see my son on the way home & the fridge keeps working while the car is parked.

I put a meter on the plug on our Polo with the ignition off & had no power going to it. Once something is plugged in it becomes live. Something must move in the socket to switch it on.

Interesting. Tried it again with various plug in devices (lead light, air pump, charger) but definitely no power with ignition off and key out.

What do other Polo owners think?

Definitely no power going to the ciggy lighter socket with the ignition off. Had to splice in a ACC line for the aftermarket headunit (so it knows when the ignition's on) and I took it off the ciggy lighter. Have not noticed any wiring to any switch that turns on the socket with an accessory inserted either.

Not sure if it differs between model year however.

Mine is '01 model Polo & I just went out & checked it again & it is live all the time. My Golf is '06 model, also live but I have read about other models[Jetta] that turn off with the ignition. In the UK the cig. lighter in the front of a T4 does not turn off with the ijnition but in Aust. it does.
