Cooling Power: Insulated Bags vs Coolers
Temperature Retention
Many people ask how long insulated bags and coolers can keep items cold. This depends on the insulation materials and manufacturing process. Insulated bags use foam or aluminum to slow heat transfer. Coolers have thicker insulation layers and waterproof linings, resulting in better insulation.

|---|---|---|
| Temperature Retention | Up to 24 hours | 5-7 days |
| Safe Temp Duration | 14.5h (37.6-45.1°F) | 36-45h (<40°F) |
| 24-hour ice retention | Half ice left after 24h | Most ice left after 24h |
Insulated boxes like the KUER 110QT can maintain low temperatures for extended periods, making them ideal for camping or long outdoor trips.
