Make the Most Out of Your Cooler: How to Maximize Ice Life
Last Updated by Brandon F. on June 21, 2019
Here at TheCoolerZone, we are always searching for the best coolers when it comes to ice retention. Over the last few years, cooler brands have pushed the envelope in cooling technology thanks to a host of features including specialized insulation, super thick walls, large sealing gaskets, and more.
However, let’s face it: not everybody can afford to buy the latest and greatest cooler. And furthermore, the coolers that are at the top in regards to ice retention tend to be quite bulky and heavy. For some, it is worth sacrificing some ice retention in order to have a cooler that is easier to carry and store.
But have no fear! There are plenty of ways to really stretch the performance of your existing cooler or push the limits on what some of the more affordable coolers on the market are capable of.
In this article, we will go over some of our favorite ways to maximize your cooler’s ice life. Most of these are simple in nature, with quite a few requiring no out of pocket expenses by you. And even the ones that do require small purchases shouldn’t hit your wallet too hard.
So let’s begin!
Add More Ice!
This one may seem like a no-brainer, but increasing how much ice you put in your cooler will have a direct effect on overall ice life. If you plan on going out for a long excursion (particularly during the summer months), make sure to put as much ice in the cooler as possible. A common mistake that people make is to forget to top off the top of their cooler with ice after filling it with items. That extra bit of ice on top can add several hours to your cooler’s ice life
Pre-chill Your Cooler the Night Before
Pre-chilling your cooler consists of getting the cooler itself to a cold temperature before putting in ice. With the cooler already at a near-freezing condition, there will not be as much stored heat that would transfer over to the ice, causing it to melt faster.
There are two popular methods to pre-chill your cooler. First, you can simply put your cooler inside your refrigerator or freezer the night before. Obviously, not everybody has the space in their freezer or refrigerator to put their cooler so this one will be on a case-by-case basis. The more popular approach is to fill your cooler with ice beforehand. This could be considered the “sacrificial ice”.
It will help to bring the cooler down to a lower overall temperature. In the morning, empty out any melted ice and top back up with fresh ice. The new ice should last longer since the cooler is already chilled down.
Use Ice Packs
Ice packs are typically used with soft-sided coolers, but they can also be a great addition to larger, hard-sided coolers as well. In fact, some brands have already utilized ice packs in their hard-sided coolers (Rubbermaid Gott Marine Cooler, for instance).
Ice packs are made of special chemicals that are oftentimes colder than ice and also more resilient to being exposed to heat. This means that an ice pack is capable of getting colder and staying colder longer than an equivalent amount of ice.
Adding a few ice packs in with your regular ice has the double benefit of providing extra chilling power in addition to taking some of the load off of your ice, helping it to last longer as well.
Minimize How Often You Open Your Cooler and For How Long
It might not seem to make a big difference, but opening up your cooler to access items has a big effect on the ice. The warm outside air is able to rush in, resulting in warmer air surrounding the ice. This causes your ice to melt much faster since the temperature gradient between the ice and the air will increase.
Because of this, it is smart to minimize how often you open your cooler. In addition to this, try to keep the cooler open for as short of a period as possible.
A good way to assist with this is to make a “cooler map”. Just grab a piece of paper and sketch out which area of your cooler certain items are on. For instance, put your sodas on the left, beer in the middle, and cold cuts on the right (and of course document this on your cooler map). When you open your cooler up, you will know exactly where the items you are looking for are located. This helps to minimize you having to search around in the ice to find it.
Consider Your Cooler’s Environment
If you are able to, try to put your cooler in an optimal location that takes it out of the heat. The best place for a cooler is in a shaded area, preferably indoors. If you leave your cooler out in the direct sun, it is going to significantly affect the life of the ice inside.
If you have your cooler in your boat on the lake, be sure to stick it underneath the hull or at least under the canopy outside of the sun. If you have your cooler in your truck, try to stick it inside on your seat if it will fit. If it is too large, at least try to put it under your truck cover.
If you have seen our many great cooler reviews, you will notice that we have a big range for the expected ice life of a cooler. This is to account for outside factors such as the environment. In our experience, we have seen a cooler’s ice increase by multiple days by simply putting it in a cool place as opposed to being in the direct sun.
Chill the Items You are Putting in the Cooler Beforehand
If you are able to, try to chill any items that you plan to store in your cooler beforehand. Having the items already cold will help to avoid the initial rush of melting ice that happens whenever warm items first touch the ice. This plus pre-chilling your cooler packs a powerful 1-2 punch!
Elevate Your Cooler
Believe it or not, there is a lot of heat exchange that goes in between the base of your cooler and the surface that it is touching. This is a big reason why many modern coolers come with elevated legs: to minimize the contact area between the base and the ground. You may get a slight boost in ice life if you are able to place your cooler on a cool surface as opposed to the warm ground.
These were just a few of our favorite tips for maximizing the ice life in your cooler. While the best way to get the ice numbers you want is to simply go out and purchase one of the new premium coolers that have the most advanced technology, we know that is not feasible for everybody. But even if a new cooler isn’t in your immediate plans, there are plenty of ways to extend your ice life by hours if not days.
