Note that availability may vary by location.

We often have power outages due to extreme weather, and these are a necessity to have stocked in our freezer. My entire top shelf is packed with them, as are the interior door shelves. We do have a gas generator, but when electricity is out, that also applies to our local gas stations, so the pumps won’t work. – Hip Reader, Thia

These are great because they are small enough that they’ll fit in tight spaces other cooler packs will not. We’ve been using these for 3+ years now at the beach and on the boat. They work great, and in a decent cooler, they last about 6-10 hours, depending on how cold the items are you have in there and how many of these you use. Great value for the price!

This very cheap ice block is perfect for keeping everything from drinks to food cool. The performance of the block is perfect for throwing it in a lunchbox and knowing that your drinks will still be cold hours later. The look and color of the block itself are decent, and the block is easy to clean. It has a high durability as well. A perfect little block to keep things cool!
