Introducing the
LIFETIME COOLER

How did we get 7 days?

Coolers have been claiming how long their ice will last for years. 5 days, 7 days, 10 days – each claimed with unrealistic tests and unknown methods. There is no standard way of testing your cooler’s ice retention. We want you to know exactly how we tested our cooler, and other top coolers on the market, so you can recreate the same tests if you want. Try us against our competition - we know we’ll stack up.

To begin, we brought all our coolers, along with chosen competitor coolers, into a controlled 72 degree room 24 hours before testing started. To achieve an even more optimal level of performance you can pre-chill your cooler with dry ice (see our video below), however we were only concerned with a level playing field in this test.

After bringing the coolers to a consistent room temperature, we added ice. The ice temperature was 6 degrees Fahrenheit, which is the temperature of a normal freezer. Each cooler was filled with .75 lb. of ice per quart of stated capacity. Our cooler is 55 quarts, so we used 41.25 lb. of ice in the Lifetime Cooler.

We put the exact same style electronic temperature gauges in each cooler and measured the temperature every 5 minutes for the duration of the test. The lid was kept closed at all times. Once the temperature of the cooler rose above 40 degrees we ended the test for that cooler.

This was our test: simple, but effective. All coolers were tested under the same circumstances, so we are confident in our results. But, if you have questions, try it out!

Tips & Techniques

Ice Retention Tips

We all know that the main reason to have a cooler is to keep your things cold. Ice retention is the key to making this happen. The longer your cooler keeps ice, the longer your items will stay cold!

Here are some tips to keep your ice and all your items colder, for a longer period of time.

1. Pre-chill your cooler. Put regular ice or dry ice in your cooler the night before.
2. Freeze or refrigerate your food and drinks before packing.
3. Use a mix of block ice and regular ice. Block ice won’t chill food or contents as quickly, but will last longer.
4. Air is the enemy. Fill any empty spaces with extra ice or frozen water bottles.
5. Hot air rises. Keep food at the bottom and the ice on top.
6. Keep the lid closed. Limit opening your cooler to keep hot air out.
7. Don’t drain the water. The cold melted water will help retain the temperature inside your cooler.
8. Keep in the shade. Direct sunlight and extreme heat will cause your cooler to heat up faster.
