USB Charger Plug - Battery Discharge

Is it safe to leave a USB charger plugged into the cigarette lighter port next to the cup holder (without a device plugged in) overnight while the car is parked? Will this prematurely discharge the battery?

It will not. The 12v sockets turn off ~10 minutes after you turn the car off. You can't drain your battery that way even if there WERE something plugged into the charger.

Thanks for clarifying this.

If anyone is looking for a low-profile USB charger, AUKEY makes a great USB-A/USB-C plug available on Amazon that almost sits flush in the cigarette lighter port.
