how many hours does cold water last?

That's a very subjective question. It depends on how cold the water is when you pour it into the bottle. Also depends on what's the temperature outside the bottle. If its freezing outside then the bottle will keep the water cold for hours/days. If its a 100 degrees outside don't expect the bottle to keep the water cold for more than 30 minutes. If you put the bottle in the oven that's heated that's another story. So where do you want to take this bottle?

The amount of water to ice doesn't necessarily matter. If you put more ice in, you can go longer before adding additional ice. I'm sure two trays would last several hours.

I believe a few hours. just like regular ice would. :) But i bought them just for me and my boyfriend so we usually have more than enough to get new ones and trade them out if need be. But they seem to work pretty nicely....we like them! :)

I fill my machine with water once every morning and leave the setting on medium-high. I've found it will last all day and night on one tank of water. So around 24 hours

I think it depends on how much water you started with. Mine will keep ice cubes for about 24 hours as long as I started with mostly ice.

It will last app. 12 hours on a tank, the nice feature of this cooler is that when it starts getting a little low you can use the built in timer, from 1 to 4 hours. This thing is worth the money.

They say according to instructions, 45 seconds. Usually we make the water before dinner starts and open it after we sit down for dinner. It seems to absorb the CO2 better when cold.

My will last 20 hours every day I use this. That's how often I use My last for 20 hours each time I use this. Only I use distiller water. I really do like this unit.

The packs stay cold for an hour or so; you may need to replace; however it's not medically advisable to leave a cold pack next to skin for over 20 minutes. I do, but I wrap it in a kitchen towel to avoid frostbite.

I have only used it for cold items. With an ice pack it stays cold for about 6 hours.

If you don't use an ice bag not long at all. With a ice bag about 6-7 hours.

Am sorry I cannot be exact - best answer from memory is 20-30 minutes. Faster than boiling that amount of cold water on stove top.

It doesn't take long at all to cool. Once you wet it, it immediately starts cooling. Yes, it feels cold and the cold lasts for several hours or as long as it's wet. I used mine inside the house next to me for hotflashes and it was really cold. I haven't tried to use it outside yet though.

I fill mine completely with ice then add ice cold water from the fridge, when it is kept in an air conditioned setting I have had ice last to the next day. When I add room temp water to the ice I still have ice at the end of the day, but not much.

For me has lasted all night, I haven't let it run more that 8 hours, but it's lasted at least until then. The water was about 1/4 full after that time, so I'm assuming it can run close to 10 hours.

I make cold tea with it. I use 30 leaves and 4 cups of water, bring it to a boil, simmer it for 20 minutes. It sits for about 12 hours and then I remove the leaves (squeeze them dry) and refrigerate it. I drink a cup a day, cold.
