## Description

Non-Hazardous cooler gel pack out performs ice and other gel packs. Originally designed to keep blood shipments cold, these packs have as much energy as a freezer! Packs are designed to phase-change at 18 degrees (go from solid to liquid). This releases the largest amount of energy at freezer temperatures to get your food and beverages cold quickly. Put them in the freezer for 12-24 hours (depending of you stack them) and you will have portable cooling power that actually accelerates cooling CoolerShock is shipped to you dry. Simply add water, zip it closed and permanently seal with an iron or screw the cap on. Easy instructions included and video at CoolerShock web site. Pack turns to gel in 15 minutes. It lasts all day (24 hours) in size matched coolers listed at our website. Great for fishing, boating, parties and tailgating. Add room temperature drinks to your cooler and drink them at near freezing temperatures a few hours later. Drinks should not be left in direct contact with ice packs for a prolonged period as they can freeze. Great reviews, what about the bad reviews? All ice packs have a limited life span depending on the number of times you freeze them. They all eventually split from the freeze thaw process. Cooler Shock pays for itself in about 5 uses (ice you didn’t buy). Cooler Shock can cycle (freeze-thaw) 80 to 300 times, depending on if they are getting knocked around a lot while frozen, or if they are mixed in with sharp objects. Some users use them every day. That is a lot of cycling! For such constant use, we added the 8 mil Sport clear bags as an accessory. This helps with commercial use as well. We also recognized that we could do better so in 2018 we converted all of our bags to the 8 mil nylon coated type. We increased durability 50%. Our 1-year guarantee – If you have any issues at all, contact us directly for free replacements. We are easy to find, and we are very responsive. Details are on our website at CoolerShock.com

## Questions & Answers

**Q: How long do these stay frozen for ?**
A: Mine have stayed frozen for approximately 9-10 hrs. I left food in the cooler,which was well-insulated, and it which was still cold when I got home. This was kept in office setting with temps in room in the 70’s.

**Q: When you say that this item is colder than ice, what does that mean? ice can be cooled to any temperature unless i'm mistaken. a rock can be 18*f.**
A: Karæthon's answer is correct.  Freezing or melting overcomes the  "latent heat of fusion" which is about the same heat as is required to raise the temperature of (for example) liquid water by almost 80°F, or frozen water (ice) by about 150°F.   So an ice pack in a cooler will spend most of its time at it's melting point. Once it's all melted, the subsequent temperature rise will be very quick.

**Q: Are these reusable?**
A: They are reusable.  There is an initial "just add water" setup to change the dry powder to gel, then you throw them in the freezer for several hours and they are ready for use.

**Q: If I were to use two of these together, would I have similar cooling capacity as one of the medium-sized packs?**
A: Not positive of that but I am amazed at how well these things work.  4 of them keeps a large cooler super cold.
