Why you'll love it
Twice the Cooling. Zero Compromise.
Or One Big 40L Space.
Need more room for one big load? Combine both compartments into a single larger zone with an extended range of +24°C to –22°C — from gentle chilling to deep freezing.
Power It Your Way.
Run it on DC power in your car, SUV or RV, or on AC power at home. Use MAX mode for fast pull-down cooling, or switch to ECO mode for efficient low-power operation on longer trips.
Control From Your Phone.
With the MyKilig App, you can monitor and adjust both zones from your phone — so you can check on your food and drinks without leaving your seat or opening the lid.

FAQ
Questions, answered
Can it chill and freeze at the same time?
Yes. The Subzero 40D has two independently controlled compartments — keep one as a fridge for fresh food and drinks while the other works as a freezer, each set separately from +20°C to –20°C.
Can I use both compartments as one large space?
Yes. You can combine both compartments into a single larger zone with an extended temperature range of +24°C to –22°C — useful when you need to fit bigger loads at one temperature.
Can I use it both in my vehicle and at home?
Yes. The 40D supports DC power for cars, SUVs and RVs, and AC power for home or indoor use — so it works as a travel fridge on the road and extra cold storage at home.
What is the difference between MAX and ECO mode?
MAX Mode provides faster, more powerful cooling when you need to bring the temperature down quickly. ECO Mode uses less power for more efficient long-duration operation.
Can I control it from my phone?
Yes. The MyKilig App lets you monitor and adjust the 40D from your phone, including managing the temperature of its zones.
What can I use it for?
It's designed for long drives, camping, boating, RV and caravan travel, and even as extra cold storage at home.
