E9x Series power from socket when car off ??

[Smuler]

When an E9x series BMW has the engine off, and no keys in ignition, is there any power coming from cigarette lighter socket and / or any other power outlet such as USB which could be used, for example, to charge a phone or run an in car dash camera?

Thanks

Thanks for replies. Step backwards from the E46 in my humble opinion. I caught some great footage when mine was parked; neighbour reversed into the car and even thought his was from behind (and camera is front facing) I still caught the impact as the car shook and on the audio the confession. Including all the tears and the row with her husband
