Power Outlets In Dash

[lars-ss]

Does anyone know WHY the power outlets in the dash REMAIN powered when the AV is turned off?

My wife has a little 110v converter that she plugs her cell phone into when she is driving the AV. The converter has a little green light that comes on when it is getting power through the in-dash outlet.

When we turn off the AV, the converter STAYS powered on?

So we BELIEVE that in order to avoid power drain, we must unplug the converter every time....

Anyone else seeing this, and do you know why it does that?

Checked the manual already, could find nothing about it.....

I think you may be looking at the wrong manual. Most power inverters have a low battery shutdown.

Most of us have 12 volt chargers on our cell phones. That way theres no problem of battery drain and a lot less wires to mess with.

Good question...run down protection...I have seen no mention of this in the owners manual or on my window sticker.

Do both the power outlets stay on? I thought one was supposed to go off with the ignition. I will have to look in the morn.

If you have a phone that you leave plugged in and think that it's going to drain your battery, then you must have one hell of a big phone. There is no way that a cell phone is going to drain your battery especially when all the trucks now have the run down protection.

Your Chevrolet Avalanche is equipped with Retained Accesory Power. Power windows and sunroof as well as radio have power to them for 20 minutes after the key is removed, until a door is opened (so remember that the next time you shut it down with the back window still rolled down). You have 20 minutes of cigarette lighter power after the key is removed, even if the door is opened.

It's in the owner's manual...

We have had phones in our last four cars and the "green light" has always stayed on at the power cord. I would imagine this could only be a problem in certain vehicles if they were left parked for months at a time.

Hmmm, my cell phone has been plugged in since Thursday (snow kept me from work on Friday) and the power adapter is still on. It didn't shut off after twenty minutes. I wonder if the AMOUNT of the drain matters? If I leave the back gate open, the lights only stays on for a short time: ten or twenty minutes (yes, I added a pin switch to the back gate to turn on the lights).

I have left my cell phone power cord plugged in (green light on) for several days in my Chev Monte Carlo with no effect on the battery. I assume it would be the same with my Avalanche. The power save and time feature seems to be the same.

I just keep my phone charged and I unplug it the rest of the time, but I keep a charger in the truck and in the house. The lithium ion batteries in the phones seem to last a very long time.

2 points:

1) The Av's battery protection (if it exists) doesn't work. I've run the battery dry twice now while installing stereo gear and amps.

2) My radar detector stays on 24 hours a day. While the dome light, cargo lights, and other accessories will shut down after 20 minutes, the in-dash power outlets do not.

The question as I read it is if you leave a 110 volt inverter pluged in, will it run down the battery just charging a cell phone?
I believe the inverter may run the battery down even if it has nothing pluged in to it.
