Last refreshed Jun 15, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
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.
Pros and cons
- 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.
