Has anyone timed how long it will keep coffee or tea warm?

I don't believe the one is supposed to put hot or warm drinks in this bottle. It says on the package that it is for cold drinks. It does an excellent job of keeping things cold.

Instructions say it is not for hot beverages because the is no place for steam to escape and pressure would be created.

I have only used this for coffee. I pour boiling water in it and let it sit for 10 minutes. Pour out the hot water and add the hot coffee. The coffee stays warm till the end of the day even after opening it several times. I left this home by accident one day and found the coffee still warm after 12 hours.

After about an hour or so it will automatically shut off to save on energy. If I need it on longer to stay hot, I simply push the "Brew Now" button again and the warmer will keep the coffee hot.

Yes I use it for tea or coffee. It works really well and keeps liquids hot or cold for about 3 hours.

It varies with the beverage and whether or not you used hot water to heat up the mug before you put your beverage into it. Good 4 hours sometimes longer. Imagine it would be shorter time if in a cold area. I keep my car warm.

Do not rely on this for that type of warming--depending on the quantity you need, a cup that is already warm will stay warm. I just do not think it will be your first consideration.

I preheat the carafe with hot water for several minutes. Then I empty the carafe and pour the coffee or tea into the carafe. The coffee/tea stays hot for at least 3 to 4 hours.

I'd say my tea or coffee stays hot for at least an hour. If I forget about it and it gets cool, I pop it in the microwave for about 30 seconds. I love this cup and wouldn't be without it. So easy to drink from without spills or dribbles.

Yes! As a matter of fact, I am drinking my second cup right now, 30 minutes after making the coffee. It's hot! The warmer goes off automatically after one hour.

It will stay hot for maybe 10 or 15 minutes. About the same time as a cup of coffee or tea.

this warmer i keep on all day. it has a built in timer (on and off). about 20 min till warm cup. if you want a quicker way to warm up your cup just put some water in it and place in the microwave for a min or two.

Yep, we have one at the office and it keeps the coffee hot/warm for about half a day. Any longer than that and it starts to get lukewarm/cold.

Not like a standard thermos would. I'd say you have maybe 15 min until things cool down. It only takes probably 8 oz of coffee so it isn't very big either.

Tea light candle goes inside... grate goes on top (see illustration) .... put cast iron tea pot (or metal or ceramic) on top of grate.. light candle.. enjoy! Keeps tea pot warm for about an hour. Some people just place a ceramic mug directly on the grate to keep their cup of coffee warm... also can be used to keep melted butter "melted"... just be sure to use a heat tolerant vessel. Enjoy!

Your question is oddly worded...but yes, you can set a timer, heating your tea (say) for 70 seconds.

I haven't actually timed it but I can drink it all before it gets cold. If I had to guess I would say an hour. But on days where I am going to make an iced tea, I place my KATI cup on from of my office desk fan and it does cool pretty quick. I hope that helps.

Yes, it does. I'd estimate about an hour to an hour and a half, depending on hot hot your water started. It's roughly 2 hours until the tea hits room temperature (which only happens when I forget about it).
