Overview
The Smad DSX-40B2E-DEA is a 1.4 cu ft locking mini fridge that runs on 12V DC or 110V AC, built for semi trucks, RVs and similar mobile use, with a temperature range of 32-50F and a reversible door.
It uses NH3 refrigerant rather than a running compressor, which is why Smad markets it as near silent, and reviewers confirm it is quiet in most settings, though one buyer found it loud for bedroom use specifically. The lock is aimed at keeping food secure during vehicle transit rather than child safety.
