Operating the Cooler/Warmer
The Koolatron P20 offers both cooling and warming functions. The mode is determined by the polarity of the power plug connection.
Cooling Mode:
To activate cooling, ensure the power cord's arrow aligns with the BLUE dot on the cooler's power input. In this mode, the unit will cool contents to approximately 40°F (22°C) below the surrounding ambient temperature. For optimal cooling, pre-chill items before placing them in the cooler.
Warming Mode:
To activate warming, ensure the power cord's arrow aligns with the RED dot on the cooler's power input. The unit can warm contents up to 140°F (60°C). This is suitable for keeping food warm during travel.
Capacity:
The 17-liter capacity can hold up to 23 standard 12-ounce (355 mL) cans. Arrange items to allow for proper air circulation inside the unit for best performance.
