Have you left this unit plugged in for long periods of time - and if so, does it drain the battery of your car?

I have left it plugged in on my Hummer H3 and I note that the port is getting 12 volts even parked. The unit then is hot to the touch and I really don't think it will live a long life under those conditions. If the port was switched I would leave it plugged in, but as it is, I remove it when I'm not needing it.

I have left it plugged into my '97 Olds Cutlass for over a week before starting the engine and had no problem starting.

Actually my husband uses it in his car, and he does tend to leave it plugged in. I myself don't recommend it.

I've never had a problem with mine. I just leave it plugged in all the time why my car sits. For a few days to a week in the Northeast climate. I unplug it before I start my car. WFP

I leave mine plugged in all the time when not in use. The battery hasn't been a problem for me.

Yes, you can leave it plugged in 24/7. If you were not going to start your car for a month, you might want to unplug it, but even then, it wouldn't use enough power to drain your battery. If you have a digital watch, think how long it will run on it's little tiny battery. Just about the same thing with this little voltage meter. I have mine in a boat and I never unplug it.

No. It keeps drawing off the car battery until you unplug it. I got the 120v adapter so I could plug into wall outlet or extension cord.

I do not know from personal experience the answer and we did not leave it plugged in at night but depending on the temperature in the car the unit holds a cool temperature very well and we often left it for 6 to 8 hours disconnected because I had a borrowed car and was afraid it might draw down the battery. We really liked the unit. It is ideal for a road trip.

Your 12-volt socket is probably not energized when the car is turned off, so not an issue. If it is energized with the car off, this unit would put a small drain on the battery, so you would want to unplug it when not in use. Obviously there is no issue if the car is running.

No, I keep mine plugged in whenever I'm not using it and it still plays for 7 hours or more on battery.

I have experienced no battery drain issues. I almost always turn it off when not in use as a precautionary measure. It has been on no longer than 24 to 48 hours without cranking a vehicle. Like I said earlier , I have never had any issues. It seems to use minimal power.

We have left it plugged in to our car for up to 6 hours without losing power for the car. I also have the electrical plug in so I can plug it in overnight at motel rooms. Have never tried it overnight on the car battery. Some cars will shut off the battery after a certain length of time so you would want to check on that before you set out on a trip. Hope that this helps. We have found that if you place a frozen bag of water or ice in the cooler it also helps keep items colder on hot days. I some times double bag it so as to prevent leaks. I don't use the blue ice packs as they take up to much room. We have left it plugged in to our car for up to 6 hours without losing power for the car.

It depends on your car some cars have slow constant drains in them from security systems and lighting and advanced electronics and these would trick the Sansour into giving incorrect readings on your batteries voltage so most of the time the battery is suggested to be disconnected but if it's just for a little top off charge you can get away with it

I have not had that issue. Does your car outlet go off when your car's off? I have two outlets on my console, one turns off with the car and one remains active. I plug into my always active port so if it's in the base it's charging.

That is entirely up to you. I leave it plugged in on long trips to monitor performance, bit take it out when we get home. It is used mostly as a code reader for my son's truck.

No. You can leave it plugged in as I do. I do press the off button when I'm leaving the car, however.

Think instructions say leave plunged in whenever car not in use. Left mine plugged in during winter.
