Phone charger draining battery

borske · July 28, 2015

Just got my truck and I noticed my phone charger still charges and is pulling power even when my truck is off.

Will this drain a battery if left for several days?

Your 12v should always be an hot receptacle. So you can charge something when truck off. If you leave your charge cable plugged in, and it has a light on it, then it could drain your battery, after awhile. Prob a week

Your 110v outlet needs a power inverter, which your trucks needs to be running for. And your usb's are only powered when your radio is powered.

No not at all. I keep my charger plugged in all the time. I'll leave my truck setting for 3+ days on a weekend and it will be fine

Perfectly normal. Domestics keep it hot at all and imports it's typically only hot with the key in the ACC or RUN position.

You can also move the fuse in your fuse box so that the outlet (cigarette lighter outlet under the dash) only receives power when the truck is on and it will turn off with the truck like the radio does after you shut the engine off and open the driver door. I forget the fuse number but it's in the driver side fuse box. I changed it in mine for this very reason....I didn't want the green light on my phone charger draining the battery. Somewhere in the manual it mentions this as well.

I leave my charger plugged in all the time. My truck sits weeks at a time, and the battery has never been drained from the tiny light on the charger. You're fine.

The center console 12v is switched.. I have my camera plugged into it and it turns off when I shut the truck down and open the drivers door..

I think it depends on if you have an LT or an LTZ. I have front bench seats in my LT and the 12v plug below the dash is not switched from the factory. I'm not sure about the LTZ's though with the center console. I should have clarified that.

I have the LT and my console 12V turns off with the ignition switch. The dash 12V is hot all the time.

I would love more info on this. I can't find anything in the manual. I would love my outlets to switch off with the key. I have an SLT with the console. If this is something a guy can customize I would be a happy camper.

This is from a thread I started and I was able to use the info in this post to change the behavior of my in-dash accessory outlet to be ignition-controlled for power.
