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. Reviews on real-world cooling are split: one trucker reported steady performance in a Peterbilt cab, another said it worked fine in 95 degree desert air, but a separate buyer said the fridge stopped cooling once temperatures hit 80 F, so ambient heat tolerance may not be consistent across units.
- 1.4 cu ft mini fridge, black
- 12V DC / 110V AC with car adapter
- Locking door, reversible hinge
- NH3 refrigerant, under 10 dB noise
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.
What buyers say
From Amazon customer reviews.
A trucker running the fridge in a Peterbilt cab said it kept food from spoiling, and another buyer reported it working fine in 95 degree desert air. But a different owner said it stopped cooling entirely once temperatures reached 80 F, and one buyer received a unit with width and depth reversed from what was listed.

Questions about the Smad XC-40
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Will this fridge work in a hot truck cab?
Results vary in reviews. One driver reported it working fine in 95 degree desert heat, while another said it stopped cooling above 80 F.
Does it need a compressor?
No, it uses NH3 absorption cooling and should stand upright for twelve hours before first use.
What are the actual dimensions?
One buyer measured their unit at 16 inches wide by 18 inches deep, the reverse of what was listed, so confirm dimensions match your space before buying.
