I find that about 12 hrs in a deep freeze will get them cold. I work 12 hr shifts and if I have the packs frozen the day before the last approximatly 3 hrs each. I don't wear for the first 2 hrs of work and I'm cool all day long

We use dry ice. It keeps the packs frozen. The packs themselves also last three hours or so for my mom. Ice won't re-freeze them but will cool them enough to be of use again

We did put it in a cooler filled with ice until we got to the bee yard. The temp was 90 degrees and they didn't last but about 1 hour and 20 min. We put them back in the cooler and when we got to the next yard it was cool nothing more and did not keep us cool at all.

They will get cold but will not start to freeze. It also depends on your cooler. Usually mine lasts for an hour but I have multiple sclerosis and put off alot of heat. If it's hot outside they will melt alot faster too. Your best way would be to freeze all that you have, and put them in the cooler and use them as needed.

It makes ice rather quickly, about 10 cubes every 7 minutes or so (that's just a guess). Problem is the bucket the ice goes in is small, and once it's full it stops making ice until you empty it. So, if you stood there and babysat it, emptying the ice into your ice bin every 20 minutes or so, you could fill a large bin in less than 2 hours. The ice that comes out is only 32 degrees (and melting), and the ice bin in your refrigerator is usually around zero degrees so the ice will stick together as it cools down. My guess is one refill of water would be all you need to stock up your refrigerator.

Don't buy any ice pack from Amazon, they melt too quick. I would go to target or an actual camping store to buy the ice packs.

Only one person on here is right, these packs stay cold forever without refreezing them. Anyone who keeps them in the freezer is just wasting energy. They use nano-size perpetual motion devices as minature a/c units and vent through osmosis.

A trick my mother showed me about refreeze is place two ice cubes in ziplock bag and place in freezer. If the ice cubes are frozen flat the the freezer was off long enough for the cubs to totally melt then refreeze as a sheet of water. This is a follow up to my previous answer for the acu-rite

I personally use two little ice pack/bricks during the day. I do live in the tropical state if Qld on Australia so it's quite hot. Keeps cold for hours and hours. Great investment!

No. Not at all, the other posted answers are wrong. These packs stay cold forever. You never need to 'refreeze' them, as they are eternally cold.

Ice pack does freeze solid. As for using it in your cooler, I'm uncertain as to how long it will remain solid. I'd suggest just trying it out. However, I think it might work. My use of it is for therapy purposes, and I would highly recommend it for that. It's better than any locally sold.

Youshould get 18-24 hours of cold from these ice packs. When travelling I usually re-froze my packs over nights. Even in the hotels I stayed in I was able to request a refrigerator that kept the packs cold enough to use the next day,all day. Hope this helped.

They're the best ice packs I've ever used. Because they're small, it's easy to pack them strategically in order to keep food/drinks cold. I ordered a box of 48, and only use half in a large chest. You won't be disappointed.

Sorry we do not ship with any ice packs. They do not need any refrigeration for short time during shipping. When opened for use or when kept in inventory they should be kept under refrigeration. Thank you House of Nutrition

The packs are thinner, individual-type cells so they defrost quickly. We usually keep it in a cooler with drinks and ice and it stays frozen through the game.I think it would defrost quickly if not in a cooler with ice.

My husband uses it to ice his knees after taking a shower & before going to work. It slowly melts over a period of 2 hours, out of the freezer, on the human body. I used to take them in a small cooler for after physical therapy & as long as the cooler is cold to start with, they lasted about the same. I have placed them in freezer bags about the same size for multiple use. The seams on these newer ones are fragile, this way, if the gel starts to leak, you can still use it. We used the one he got at the hospital for 5 years--but we took really good care of it. That's how we got the name & information to get the new ones, but we didn't need a case. I'm glad amazon offers them as an add on. Saves $. My husband uses it to ice his knees after taking a shower & before going to work.

I also noticed the ice melting sooner than I thought it would. Since they are large, I thought they would stay much longer than regular ice. I am not sure where I saw it, but the supplier had some tips on how to keep the ice frozen longer...I will look and see if I can find where that was. Maybe if you contact the supplier - maybe reply to an email they might send...they might be able to get you this info faster...just a thought.

These are re-freezable ice packs, not the one-time use chemical ice packs. Just pop it in the freezer for a few hours and it will be hard as a rock and ice cold for a few hours use.

It is not that simple. They may stay cold in a good cooler all day, on the table maybe an hour, but on a hot swollen joint maybe 15 minutes. You want cold packs to transfer heat quickly so that they cool things. A better question is how much heat can they absorb? I put it in a cheap cooler with a liter bottle of water that starts at room temp. The bottle of water cools to about 50 degrees after a couple of hours and lasts about 5 hours. Being segmented it has more surface area and transfers heat faster than a solid pack. The solid pack stays frozen longer, but the water does not get as cool. It is not that simple.

I have filled it with ice and water to go to work on a hot day. At the end of the day, I throw it into my lunch bag and forget about it. The next day when I arrive at work, it still has ice in it. Hope this answers your question.
