Smart control via app: with the integrated Bluetooth function, the cool box can be easily controlled via the DOMETIC mobile cooling app. Temperature, operating status and power consumption can be monitored and adjusted directly from your smartphone for maximum control on the go.
Robust design and well thought-out features: the sturdy housing with reinforced corners, stainless steel hinges and removable lid is designed for outdoor use. Ergonomic, folding handles, interior lighting, USB port for charging small devices and a practical drain plug for cleaning complete the thoughtful design.
Plenty of space without ice: with a capacity of 28 litres, the CFX2 28 offers space for up to 42 cans (330 ml) or four 1.5 litre bottles. With no ice packs or ice needed, the entire interior is available for food and drinks - ideal for weekend getaways and outdoor adventures.
FLEXIBLE POWER SUPPLY & BATTERY PROTECTION: The cool box can be operated via both 12/24V DC and over 100-240V AC. An integrated 3-stage battery protection reliably prevents the deep discharge of the vehicle battery - especially important during longer trips or in standing operation.
Energy-efficient and powerful: the DOMETIC CFX2 28 is equipped with a highly efficient compressor that allows precise temperature control from +20 °C to -22 °C. Thanks to the energy efficiency class B and an average consumption of only 1-2 amps per hour, it is ideal for mobile use - whether in the car, boat or camping.
