1. Insulation quality
The effectiveness of a cooler depends largely on the quality of its insulation. Investing in a high-quality insulated cooler ensures better temperature maintenance and long-term freshness of stored items.

2. Ambient temperature
The outside temperature plays a vital role in the performance of your cooler. Extremely high ambient temperatures can pose challenges for even the most rugged coolers. Understanding your environment helps plan and ensure optimal cooling conditions.

3. Correct packaging
How you pack your cooler is important. Effective packaging, taking care to minimize air gaps and strategically place items, can significantly improve the performance of your cooler.
