3. Operating Instructions
3.1 Cooling Function
To activate the cooling function, ensure the cooler is properly powered. The thermoelectric unit will begin to cool the interior to approximately 27°F below the ambient temperature. For optimal cooling, pre-chill items before placing them in the bag and avoid overfilling.
3.2 Warming Function
To activate the warming function, ensure the cooler is properly powered. The thermoelectric unit will heat the interior up to approximately 140°F. For best warming results, place pre-heated items into the bag. Do not place cold items expecting them to heat up quickly from a cold state.

To clean the interior, wipe with a damp cloth and mild soap. Do not submerge the unit in water. For the exterior, wipe with a soft, dry cloth. Ensure the unit is completely dry before storing.
4.2 Storage
When not in use, ensure the cooler is empty and dry. The collapsible design allows it to be folded flat for convenient storage in small spaces.
4.3 Fan and Vent Care
Regularly check that the cooling fan and vents are free from dust, debris, or any obstructions to ensure efficient operation and prevent overheating.
5. Troubleshooting
- Unit Not Cooling/Warming: Check that the power cord is securely connected to both the cooler and the power source (vehicle socket or wall outlet). Ensure the power source is active.
- Reduced Performance: Verify that the lid is properly closed and sealed. Ensure the internal fan and external vents are not blocked. Avoid overfilling the cooler, as this can impede air circulation.
- Unusual Noise: A whisper-quiet fan is normal during operation. If you hear excessive or unusual noise, check for any obstructions in the fan or vents.
