What is the lowest Fahrenheit temperature that these are rated for?

I have no idea. We hit wind chills of -30 here a few weeks ago and they are still working fine!

Since they do not use degrees as a measurement on the dial you can only set for low which in most of these heaters is around 50 degrees. They will vary between them and the manufacturers will not guarantee any setting. They just expect you to find an adequate setting for your needs. The difference in operation time from 40 to 50 degrees is negligible in my estimation so just using the lowest setting no matter the temp should be adequate for most situations. Hope this helps.

I am using 6 of them and we aim to have them at -20 C when they go on my head and usually leave them for 20 mins (they are between -13 and 0 when I take them off to be returned to the dry ice).

85-155 F according to the settings. I don't check the exact temperatures because nothing I use it for needs precision.

150, sorry. I looked in the manual for the other settings like dehydrate...but lowest temp on presets was still 150 degrees.

They are oven safe but probably to less than 400 degrees F or 200 degrees C

There is a dial that goes from 1 - 30, with 30 being the highest heat setting. I do not know what that translates into Fahrenheit degrees. I use mine on the 30 setting. I hope this helps.

I would like to use these to experiment generating electricity. What temperatures do they handle? Thank you

i have it @ 7 Celsius , and is working fine so far. i think you can still go lower. hope this helps.

Don't know, but can tell you these are great, I have used mine in the tropics with temperatures constantly above 80 degrees and it's great.

They are slightly warm, when it is 90 degrees, they are too warm to wear, when it is zero they do not do much good. I think the sweet spot is between 45 and 65 degrees.

The documentation says that the range is -30 to 220 degrees in the Fahrenheit mode.

Just got one, and works like a charm!! Says in the manual, not to be used below 65F or above 110F.

Hi, Well I'm not sure, But I would say 60 degrees. You have to buy them. They work great. You will never buy a better brand.

Withstand Low/High temperature:-40 to 260 Celsius(-40F to 500F)That's on the website that makes these. Hope that helps

Not sure, I live in Texas. I believe the lowest temperature was around 34F and it worked perfectly fine.

These are cold weather resistant. The temperature in my area (Wisconsin) has dropped down into single digits and still worked just fine.
