A quiet, low-power option for a truck cab or small RV that cools reliably on 12V, though the DC port didn't work for one reviewer and support wasn't much help with a separate cooling failure.

Overview
Running on either 12V DC or 110V AC, the Smeta SDW-40 is a 1.2 cubic foot compact refrigerator built for truck cabs and RVs, cooling with an absorption system instead of a compressor.
Absorption cooling means no compressor noise, which several truckers and RV owners cited as the reason it doesn't disturb sleep in a cab or camper. It's sized for newer semi-truck cabs like the 2015-2025 Freightliner Cascadia, and one reviewer confirmed it fit their 2020 Cascadia with room to spare. First use needs 8-10 hours to reach set temperature, per the listing.
- 1.2 cu ft capacity, dual 12V/110V power
- Absorption cooling, no Freon, no compressor
- Reversible door and rear-mounted install
- Temperature range 32 to 53.6F with LED light
Who it's for
Truck drivers and RV or boat owners who want a small, silent fridge that runs on 12V without a compressor cycling on and off. Not a fit for anyone needing a fast-cooling fridge for immediate use, since it takes hours to reach temperature initially and can freeze contents like milk if set too cold.
What buyers say
From Amazon customer reviews.
Truckers and RV users praised the quiet absorption cooling and low power draw, with one measuring about 50 watts on the 110V setting during a cross-country run. A couple of reviewers ran into problems: one unit stopped cooling after a few months with little help from support, and another found the 12V DC port didn't work while AC power did.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs silently with no compressor noise
- Fits newer Freightliner Cascadia cabs
- Low measured power draw on 110V
- Door lock keeps contents secure while driving
- Takes 8-10 hours to reach temperature on first use
- One reviewer's 12V DC port didn't function
- One unit stopped cooling after a few months
Performance notes
Running on the 110V inverter setting, one long-haul driver measured about 50 watts draw, with actual power use varying by how often the door opens and how warm items are when loaded. The absorption system runs without a compressor cycling, which owners cited as the reason it's quiet enough not to wake someone sleeping nearby. One reviewer's DC (12V) port didn't work even though AC power did.
