How many hours will this thermos keep things hot or cold?

We use this thermos for hot water. We fill it in the afternoon and it stays hot till the next afternoon. We think if water stays that hot, food also will stay that hot and may be cold too. Hope this helps your inquiry.

I fill it with coffee at 4 am and it is still hot when I empty and clean it at 6 pm

This is simply a large insulated thermos. No heating element or electrics. It will keep your already heated or cooled beverages warm or cold for about 4 hours. Super convenient.

I have both the 16 and 32oz units. I have no cold experience but they are the best I have ever used for hot. Pre-warming is a must. I spent on average 8-9 hours in November out in below zero temps every day and the Thermos kept it warm and drinkable to the very end.

How long can I leave this on for at a time? and Does it keep the contents hot/warm?

If you preheat the mug with hot water for a few minutes it will last up to 5 hours hot. If you put it in the freezer for a few minutes it will keep things cold for up to 7 hours as advertised. Be sure and use the open and close valve. This cup has a small bottom to accommodate cup holders in cars. It does tip over easily. I love mine.

Hi Dustin...it keeps it hot, just as hot as it went in....my daughter hasn't had anything in it for more than six hours at a time but it either remains very hot or very cold....so far no complaints....

This keeps coffee hot for about five to seven hours according to my truck driving son. He filled it at 4 am and almost burned his mouth when he finally got to stop for coffee at about 10 am. Now, at the house it kept coffee hot for seven hours, I think because we warmed it with hot water first. It is stainless steel inside.

No they work perfectly well and has the same application as the more expensive thermos containers. They are well insulated and keep hot or cold for about 2-3 hours.

I seriously doubt that it will last that long. A few hours is the most I'd use it to keep food cold or hot.

Around an hour. The plastic lining changes the flavor of coffee however, I would highly suggest a thermos with a double walled stainless steel lining.

The cooler bag is insulated but is not designed to maintain heat for several hours. A thermos is recommended for keeping hot food hot. Additionally, I do not recommend putting an extremely hot container inside the cooler bag as the inside could be damaged by excessive heat. If a cold lunch is packed, an ice block should be included to maintain a cold temp for several hours. Food should already be chilled when packed. Do not store in the sun or a hot car. - Kelly Lester, ceo, EasyLunchboxes

It might work for a short while. But ultimately, if you wanted to keep something hot, I would suggest a thermos.

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.

The amount of time can vary depending on how cold it is outside. My tea is normally pretty warm evening I am outside for 45 minutes, so it does keep things warm for a while. However, it wasn't made to keep things warm and a thermos would be better for the job. Hope this helps.

It defintely keeps the food hot for at least six hours. My only complaint is you can microwave using it.

It depends also on how much you have in it and how hot/cold the liquid is. Fuller it stays hot longer. I don't usually have it full. I'd say the 4 to 6 hour range works for me. I'm also satisfied with it.

I usually keep it on for 20-30 mins, and it stays plenty cold. I haven't kept it on longer so I'm afraid that's as far as I can offer information.
