It auto shuts off in about 4.5 min from last use. Odd number but I verified it 3 times.

If you leave it on in your car it will automatically turn off after 30 minutes.

It actually does... It stays on for a LOOOONG time though, which is probably while other users thought it didn't. I want to say it will stay on for at least 20-30 minutes before shutting off. There have been times I have forgotten I plugged it in and went back to use it and it was shut off.

Sorry I don't really know. I have a habit of always just unplugging it as soon as I'm done so its automatically on next time I plug it in. Lol

This model automatically shuts itself off after so long of not being used but I don't know the exact amount of minutes

No, after the predetermined time (2,4 or 6 hours) this timer will shut off the power to whatever is plugged into it. Your only other option is off or on all of the time.

It will stay on when it is plugged in until you turn it off or use the timer to turn it off for you. I hope this answers your question.

It doesn't have automatic shut off. Will stay on until you turn it off or runs out of battery life. If you use it for alarm purposes, yoy may need ro keep ir plugged in to power supply.

Yes. The manual calls it "intelligent power off" and it apparently happens after 30 minutes even if you're using it.

Stay hot until blue light auto shuts off. Not sure how long that is but at least 30-60 mins

It automatically powers off between three and five minutes when not in use. One standard 9v battery will last approx. one year.

You can set it to turn off at 15 or 30 minutes but Itll stay in as long as you want it to without the timer.

My girlfriend uses it and told me it switches off automatically while she sleeps. She told me it stays on about three hours.

This means that it requires A/C. After plugging it in, it will run for approximately 2 1/2 hours and then shuts off automatically.

You set it by the time, so for each time period you decide if you want the power on or off. I think it's 15 min intervals

I have never left it on for that long. I would imagine it would still respond after being left on for 10-20 minutes. As long as you have enough power in your batteries.

No, it will not. It has a 15 and 30 minute setting. So you can turn it on and it'll turn off automatically.
