How long will it keep food/drinks cold if not in a refrigerator?

I pack my breakfast and lunch at 5:30am and find my lunch to be cold. I unpack my lunch bag at 5pm and the ice pack is still cold.

That would probably depend more on your ice packs but I stick a couple in with my lunch at 7 am and by noon everything is still pretty cool.

Think of a regular cooler with food in it that is cool, but not cold, and with no ice. If it is hot outside, not long at all. If you unplug it for the evening, keep it shut, and it is not too hot outside, then it will keep reasonable cool (not cold enough for milk, but enough for chees and vegetables). We did this most nights while camping.

Bear in mind this is NOT billed as a refrigerator. It says it will maintain a temperature about 40 degrees below ambient surrounding air temperature.(But I doubt that means if it's 40 degrees outside, it will be 0 degrees in the Koolatron.) I haven't put it to any heavy usage yet. My assumption based on initial testing is that you might get 2 - 4 hours before the inside temperature equals the outside temperature. This will depend on what you have inside, how tightly packed it is and what condition it is. (If the contents are frozen before the power is removed, you may get more time than I am guessing/assuming. Bear in mind this is NOT billed as a refrigerator.

It states in the description; 20-25 years if frozen, 15 years if refrigerated and 10 years if stored at room temperature. Hope that helps! :)

Almost indefinitely if it's in the refrigerator. Maybe a few weeks to a month if it is in a cabinet.

It keeps the food cold when kept in a lunch bag or desk drawer for awhile. It won't keep things really cold if it's in the sun or in warm temperatures like an un- air conditioned location. The food does need to touch it to stay cold. I use these primarily for fruit or salad mix. I'm not sure if I would trust it for a long period of time (say from the time you pack it for work and then till lunch at noon) for things that go bad easily such as mayo. Just my opinion. I hope it helps.

I am not sure. I would lean toward no, and I wouldn't put mine in the freezer. I think if the plastic got too cold it would run a real risk of cracking. However, this cup will keep ice for at least a few hours, so a frozen drink might keep a while longer than a traditional cup too.

It depends on how cold your items are. (Semi-frozen,etc). It will hold the temperature for awhile, depending on where u keep it. (Freezer, fridge, or on your desk). I keep mine in the freezer at work and will remove it about 2 hrs before I leave. My juice stays cold till I get home.

Not likely I would say it stays cold anywhere from 20-30 min tops then you need to throw it back in the freezer to cool it back down, which also takes about 30 min to make it cold again.

This is not an insulated bottle designed to keep things cold for any length of time. It's just a very good water bottle, but will need ice to stay cold.

If you were to place the item in a regular refrigerator, depending upon the temperature setting, the item would freeze within 1 to 1-1/2 hours; otherwise, if you were to use a conventional or deep freezer, the item would freeze within 20 to 30 minutes.

I put it in the freezer for 20 mins. It kept it cold for 15 mins. I hope this helped.

I keep it in my office "dorm" fridge. I don't have a freezer with that. Might work well. This helps keep soda cans cooler for awhile, but not as well as I had hoped.

Depends on your time frame and ambient temperature. It is not better or worse that other similar coolers on the market. If you are serious about keeping stuff frozen for more than a few hours you are going to need to pack with dry ice or invest in a freezer that can run off a car battery. For my purposes it keeps milk and meat cold for several days but I change put the ice every 48-72 hrs depending on how hot it is.

Well this has not insulation, it's a thin layer of stainless steel. If you put this in a cooler the food will stay cold. I use it for salads and no hot food.
