## Description

Cooler Shock 4 Mid Size Freeze Packs Screw Cap (10in x 9in) : desertcart.ae: Sporting Goods

Review: 大きい - 水を適量計って入れる作業が要るが特に困る事は無い。 ただ大きさをわかっていたつもりが想像より大きく 分厚さもあるため手持ちのクーラーボックスではそのままでは使えずに 凍らす時に折り曲げている。 Mを４つ買ったがMは一つでSを複数の方が良かったかもしれない。 まだ２つしか使っていないので残りは予冷用に使う事も考えたが 家庭用冷凍庫の場所にも限りがあるのでキャンプ前に容量に余裕のある時限定かも。 勿体無いが友人に使ってもらう事も考えよう。 用途は一泊のキャンプなので翌朝の食材も冷えたまま保存できて問題なし。 ２５Ｌくらいのボックスなら一つを曲げて入れるくらいかな 二つだと容量がかなり減ります。 ソロでＭ４つは多すぎです。
Review: Gute Kühlleistung, empfindliche Beutel - An und für sich eine gute Kühlleistung, allerdings ist einer der 4 Beutel ohne Gewalteinwirkung in der ersten Woche der Verwendung direkt unterhalb des Drehknaufs gerissen und damit unbrauchbar. Bei dem Preis meiner Meinung nach nicht akzeptabel. Mein Fazit daher: Grundsätzlich gut, aber scheinbar sehr fragil, womit es für den Einsatz in der Kühlbox in Anbetracht des Preises zu Riskant ist. Würde ich mit diesem Wissen nicht wieder kaufen.

## 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.

### ⭐⭐⭐⭐⭐ RN Mom Tested: Slim Ice Packs That Stay Cold All Shift Long
*by R***S on 11 January 2026*

I’ve been using these ice packs for about 3 months, and they’ve been holding up extremely well. The quality is impressive, and once prepared correctly, they work exactly as advertised. Important tip: Make sure to follow the directions closely. These do not work immediately. The instructions state to freeze the packs for at least 8 hours before use, which is necessary for best performance. I work at a hospital and pump breast milk during my shifts, so keeping my milk cold is non-negotiable. These ice packs keep everything ice cold for over 12 hours, which honestly impressed me. The night before work, I freeze two medium-sized packs, then place them in my cooler bag in the morning. I lay them flat while freezing so they are pretty slim, which makes it easy to stand them upright in my cooler later. The packs are very slim and space-saving, which I love—but be aware that the corners are quite sharp, so handle them carefully. The bag itself looks sleek with its black color and feels very high quality and durable. As for setup: the directions are clear, but the process is a bit particular. I’ll admit I had my husband help me because precision matters here. One key step is measuring 28 oz of water and letting it sit for a few minutes to release air bubbles (this is important!). You pour the water in using the included funnel, do not add the silicone plug yet, close the screw cap, and shake vigorously to mix the contents. Then you remove the cap again and gently squeeze out excess air before sealing it completely. If you carefully follow the instructions, you’ll be totally fine. Overall, these ice packs are reliable, long-lasting, and well-designed. I plan to purchase a larger size for our big cooler for beach trips. Highly recommended for working parents, breast milk storage, travel, or anyone who needs serious cooling power.
