I'm assuming it's a plug-in. Is it safe to run all night? Will it burn out?

Well, I haven't really run it long enough to tell whether or not it will burn out. Even at its highest speed setting the motor doesn't run very fast so you shouldn't have a problem with it burning out.

Yes, it's electric, and it's basically a fan... no problem to run all night.

I keep this plugged all the time. I turn it on when I place a cup and leave it for several hours. Usually I have it on for 3-4 hours, but there are many times that I left it on more than 5 hours, and it seems to be fine. I even left it on over night by accident, but it was fine, ...although I don't recommend it.

More than 2 hours actually. I left mine unplugged running at max brightness overnight to see how long the battery will last. I was up for more than 5 hours before falling asleep and it was still running. Light at max wasn't as bright compared to when it was plugged in though. There's most likely a circuit preventing the battery from over discharging as it turns on then off for some time still before I plugged it back in.

I will continue to run. I use mine that way about half the time. Just leave it plugged in.

I have had no problem, but I only run it for a few hours on low when i am in the room. It is a small room..I'm not sure that is a good idea, though.

It has to stay plugged in via A/C power. It is not battery operated. It is loud. As loud as you would expect a 500 Watt motor. You'll get over it once you start to use it. It is a fantastic device. Never runs out of air. Never stops blowing at full power. Get's a little warm in your hands if you don't use the black handle and air escapes out every seam, but that is normal. Clearly an overbuilt device. It's awesome!!! Best to use it outdoors to clean things as it blasts dust and dirt all over the place!

I take that to mean that it isn't designed to run for days on end. I've run it for ~20 hrs straight, no problem.

Sorry, cannot help, I have not reached the end of the run time yet. I use it about 15 min a night only, tho.

If the thermostat is wired directly to unit and pulls power from the unit it will stay lit all night. If it runs just off the battery it will not.

I leave mine on 24/7 and it's done no harm whatsoever. I believe it's meant to be an "always on" kind of device.

I need it to run the computer while I use it. the internal battery goes dead quickly (less than 1 hr) while using unplugged. Need it to power computer in use for 3 hrs using multiple applications.

it stays lit until turned off or batteries die so if plugged in it will run constantly

I've run my previous one for twelve hours or longer. However, I burnt it out when I let it run dry overnight. I'm sure it would have continued to run, had there been water to pump. The unit is so good, for so little money, I bought another.

I've run mine for over 2 hours but never until the battery ran out. I hope that helps.

I've run it for over 90 minutes total over several days on the high setting commuting to work with no indication it's running out of power. There isn't a low battery indicator on the light.

HI Grammy - I have been using the transformer for a light and not had any issues running for 5 or 6 hours an evening - the box gets warm but not dangerously so.
