Overview
The Smad XC-40 is a 1.4 cubic foot black mini fridge with 12V DC and 110V AC power, a locking door, and a car cigarette lighter adapter, aimed at truck sleepers, dorms, and bedrooms where a full refrigerator will not fit.
Smad uses NH3 refrigerant instead of a compressor and instructs buyers to stand the unit upright for twelve hours before first use.
- 1.4 cu ft mini fridge, black

Who it's for
Truckers, campers, and dorm or bedroom users who want a small locking fridge with dual power options. Less suited to anyone in consistently hot climates given the conflicting heat tolerance reports.
