HiKOKI Cordless Portable Refrigerators: The First 3-Zone Freezer, Fridge and Warmer
Quick answer: HiKOKI's lineup runs from the 36L UL18DE, the industry's first model with freezer, fridge and warmer zones at once (up to a 78°C difference between zones), down to the 10.5L UL18DD for picnics. The 25L UL18DBA and 18L UL18DC sit in between.
HiKOKI, the power tool brand under Koki Holdings in Japan, has released several cool portable refrigerators this year. The newest is the 36L cordless portable refrigerator UL18DE, which supports freezer, fridge and warmer modes together, along with the portable 10.5L UL18DD. This guide also covers the 25L and 18L upgrades released earlier in the year, so you can find the right model.
1. 36L Cordless Portable Refrigerator UL18DE
The UL18DE has a 36L capacity and supports freezer, fridge and warmer modes at the same time, with up to a 78°C difference between the three zones, an industry first. Its automatic divider detection adjusts the displayed temperature settings to the number of dividers inside.

4. 18L Cordless Portable Refrigerator UL18DC
At 18L, the UL18DC is a common size for small families and light trips. It is much smaller than the 25L, so it is easier to fit in a car, and it has the same handle and wheel design.

Common features
Beyond the three-zone UL18DE, all HiKOKI portable refrigerators accept multiple power sources: AC 100V outlet, car charger (DC 12V/24V) and battery. A battery inserted in the fridge's battery slot also charges when connected to power, so you do not need a separate charger. That makes them suitable for campers, builders and anyone who needs portable cooling or warming.
