I have one and it will go off every time I have a power surge in the house.

Hey Edward, without a little more info I can only guess at why your unit is shutting off. One possibility is if their is not enough airflow through the unit and it might be overheating. Is it located where there is enough airflow? I have had no issues with my unit.

You have to continue to hold the switch down or it shuts off. I see it as a safety.

It does not have auto shut off. It is the only one we have found that does not have auto shut off.

Don't know at what number it turns off, but it will automatically shut off when it is just about dead. Auto shut off when the device its charging is full too, or when you unplug something it will stop after a short while.

It does shut off. I believe the default time for it to shut off is 2 hours after it goes on.

It shouldn't power off completely. At most it should power down to the low fan setting.

mine shuts on and off all the time. I think it is to keep from overheating although it is ultrasonic and does not use heat. It is probably getting sticky from all the oil and probably needs cleaning.

It does not shut off by itself. Pressing the control buttons will turn it off or disconnecting the power will do the same. I recommend disconnecting the power as a good safety step anyway.

The unit doesn't shut off, but eventually it will power down. It goes into a self-cleaning mode to get rid of any build up. It can smell a little chemically, but it isn't dangerous.

The unit should shut off when the batteries reach 10.5 volts. If it's shutting off sooner than that, you may have a defective unit.

It seems to just have low heat and high heat. It gets overheated very quickly too causing it to turn off.

It's very expensive and only lasted me a year and a half at the most. I believe it has auto shut off, but it will remain in for hours before shutting off. I'm guessing the few times I left it on is the reason why it no longer works.

It goes for 15 minutes and then automatically shuts off. You have to restart it for additional time.

I don't know...have you cleaned the filter? Have you drained the water out? Is anything blocked? By shutting down, do you mean it turns off completely? It's not supposed to do that, though you may have it on a setting to save electricity where it does that...You'd probably have to read the instruction manual...and if you don't have it, maybe it's available online..good luck!

It has a switch to turn on and it shuts off automatically. It is very convenient.

It does not have an automatic shutoff. There is no switch. If it is plugged in, it is on.

No it does not. You have to remember to shut it off when you are done with it.
