Pre-cooling your cooler before use helps lower its internal temperature, making it more effective at keeping items cold.
How ​​to do it:
Place ice packs or cold packs inside the cooler for a few hours before putting your items in. This will cool the interior and create a better environment for your perishable items.

Ice packs and dry ice provide longer-lasting cold than regular ice, especially in an insulated cooler.
How ​​to do it:
Ice Packs: Use reusable ice packs that can be frozen and placed in the cooler with your items.
Dry Ice: If you need to keep something cold for a long time, consider using dry ice. However, handle with care and ensure proper ventilation as it produces carbon dioxide gas.

Proper packaging can minimize air gaps and maximize cold storage.
How ​​to do it:
Fill the cooler: Fill the cooler as full as possible. The more stuff there is in it, the less air there is to heat.
Layering: Place heavier items at the bottom and lighter items at the top. This helps keep the temperature consistent throughout the cooler.

Every time you turn on the cooler, warm air comes in, raising the temperature inside.
How ​​to do it:
Plan ahead and only open the cooler when necessary. If possible, designate one person to enter the cooler to minimize the number of times the cooler needs to be opened.

A reflective shield can help isolate the cooler from external heat sources.
How ​​to do it:
Cover your cooler with a reflective blanket or tarp when not in use, especially if it is in direct sunlight. This can help keep the cooler’s temperature cooler.

The environment surrounding the cooler can significantly affect its performance.
How ​​to do it:
Keep in the shade: Keep the cooler in a cool place away from direct sunlight.
Altitude: If possible, place the cooler on a surface that is cooler than the ground, such as a picnic table, to reduce heat transfer.

Ice will melt over time, and replacing the ice can help maintain low temperatures.
How ​​to do it:
If you notice the ice is melting, replace it with new ice or ice packs to keep the contents cold.
