Talk about a party killer! Luckily, you can count on portable coolers to stay at the right temperature for a long time. How does this work? Keep it cool and get ready to learn all the details! The insulation inside the cooler slows down the warm air through a process called convection. Thanks to the insulation, though, it happens at a slower rate. Ultimately, this helps things stay colder for a longer period of time. Due to the warm air slowing down from the insulation, a process called conduction is also unable to take place.
This is when an object loses its temperature and affects other objects nearby. Think of it like one bad apple heating up the bunch.

Empty space in your cooler is your enemy if you are trying to keep things as cold as possible for as long as possible.

As you open and close the lid to your cooler, warm air will enter, melting the ice quicker.
Organize your cooler with items that you will more frequently need to one side in order to lessen the amount of time the lid remains open.
Instead of having to dig around to find what you need, strategically organize your cooler to make each opening as efficient as possible.
