If I use it for an hour's nap will it run down my car battery?

Hey Carl, I've used mine for exactly the same thing at work at lunch time, sometimes for over an hour with no battery problem :-)

No I use it pretty much 4 to 5 days a week for 1 hour plus a day waiting in line at schools parent pickup line. My pickup has always started.

No it will not drain your battery it isnt that powerful But if you're worried about it. Inside the menu you can set it to turn off anywhere between three to ten minutes. Set it to motion detection that way it'll only come on when the car is in motion.

No it says it will drain a car battery in about 4 hours. If you can run your vehicle and charge the battery in intervals it would work, if not it will drain your battery. Car and SUV battery's are still just 12 volt battery's. SUV might have more cranking amps, but still won't hold a charge longer.

Mine ran down batteries (4) in my semi when I left it plugged in for 8 hrs. by mistake.

No, you can't use it because it can handle only small load like 10mA. Car batteries' load is in the range of 5-10A. You will burn this tester in no time.

Depends on how is your cigarette lighter wired. Most cars need the key to be turned to "accessories" in order for the cigarette lighter to have power. Once you have power you can run the fan, how long depends on your car's battery capacity. If you run the fan too long you will drain your car battery. If you do not want to drain your car battery, then you need to run your engine in order to recharge the battery as the fan drains it. So for short periods of time, no you do not need to run your engine, if you want the fan to run overnight, then most likely without running the engine you will drain your 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.

My daughter uses it for school every day so she charges it every night. We've never run the battery all the way down. She's pretty diligent about turning it off when she's not using it. I believe the keyboard will go into sleep mode after a period of inactivity.

Short answer: 8 hr use most likely will not even make a dent in the amount of charge left. I ran this fan ten hours straight on low speed in my camper and the battery was still showing 5/5 lights the next morning (no significant discharge). And yes, I realize car batteries are different from RV batteries, but the fact is it didn't even register so I'm confident a car battery can handle it as well.

It will shut off after 40 min. If it plays all night the batteries will constantly run low.

I assume you plan to use your car battery with 120v converter or an XPower 300 watt convert. They will give you over 3 hours. Good luck. Reg

It depends on where the OBD connection is in the particular car whether the actual GPS device can be seen. You'll have to check your specific situation. No, it dies not drain the battery at all.

you have to looking for which fuse when you turn the ignition on after get power so you can hookup that fuse. If you hookup the fuse always get the power yes, it will run down the car battery.

I used it with a cpap for a camping trip. One night was no problem at all. I brought in the car for a couple of hours to charge it for nights 2 and 3... it was reading low power but it held. Don't forget to fully charge it every couple of months when not in use.

depends on if your 12V outlet stays live when you take the key out of the ignition. If it turns off, like most cars, then the seat heater will turn off also. But if your outlet always has power, then yes, it will drain your battery.

That would be my big problem. If your car doesn't turn off that plug when the car is off it will stay on and run your battery down. So I've had to have my car jumped a few times when I forgot to turn it off. And that's bad for your battery.

If your car's 12V outlet works with the engine off it will. If you're going to be doing this for too long I would recommend againt it or you will end up with a dead battery.
