will this drain your car battery if the switch on the unit is turned off while it is kept plugged into your car socket?

Oh no. Even if you left it on the only thing that it powers is the LED which draws virtually no power to be a problem.

If your power source is continuous even after you turn off the ignition, there will still be a power draw. However, it's very minimal. I would think that even if you left it plugged in over night, it probably wouldn't be so detrimental that your car wouldn't start. Over the entire weekend, it might be a different story.However, I don't know for a fact, as my car's cigarette lighter is on a switched fuse, so it stops working when I turn off the ignition. Therefore, it isn't a problem for me.

It turns off instantly whether you check or uncheck it. The parking mode works only if you have an extended battery. So, don't worry about car battery drain

Yes, if you use it with your car turned off. As long as the engine's running your battery won't be drained.

This occurrence is generally referred to as "back feeding." When your car turns off the the electronics in your car are cut off from the battery and they start pulling power from a device that is plugged in. While I don't own this product hopefully my clarification of the problem will result in an answer for you.

It will turn on when you plug it in or have it in a outlet that is off until you start your car.

Yes it does stay on the entire time. It will not drain your battery if you leave it plugged in. Me personally I just unplug mine. It will save the station you programmed. Hope this helps. I enjoy mine.

No, don't leave it plugged in. It will drain the battery. The green light is cool but it drains the battery slowly but surely.

Only if you leave a device connected to it. .. At least I have no issues with it draining my truck battery

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

yes I prefer it that way. Their is no on and off switch on the unit. You can turn off the breaker but that too will cause it to recycle the settings every time it starts back up. The factory told me to leave it plugged in and it will learn your car and its charging system. The unit only supplies the voltage and amperage to the car. The car is actually the charger for it or has a charger built into it right in the line from the plug in for the charger cord to plug into.It is nice to have the car charged in a little over an hour.

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.

Yes, if you uncheck parking mode at the setting, it will shut off as soon as you turn off your car. It won't drain car battery. Don't forget to get a CPL filter if you want to reduce image reflection!

This device contains no battery. It obtains power from the same OBD-II socket that provides data about speed, RPMs, etc. As noted elsewhere, in most cars this means the device turns on and off automatically when you start and stop the car with the car's ignition switch. In a few cars, the OBD-II socket provides power even when the ignition switch is off, so you would need to plug and unplug this device each time you use the car, which would probably wear out the unit's harness rapidly.

it shouldn't drain the battery, only draw a few milliamps to keep the light lit. if you have a weak or old battery you may want to unplug it to be safe. I leave mine plugged in all the time & have had no issues.

Yes, the batteries drain much faster if you leave the switch in the ON position.
