mini fridge 4l

Most 4L mini fridges use compressor-free thermoelectric (Peltier) cooling, which keeps them relatively quiet compared with compressor models. They’re very portable—commonly weighing about 3.4–5 lb—with compact footprints and sometimes carry handles, so they’re suitable for countertops, dorms, or travel.

Wattage varies by model, but listings in this set commonly show around 55–60 watts, with at least one listing as high as 150 watts—so expect roughly a 55 W to 150 W range depending on the unit.

Most 4L mini fridges in the set use thermoelectric (Peltier) cooling rather than a compressor. Several listings describe performance of roughly 15–20°C below ambient temperature; product details for some entries also list specific single-number "coolest temperature" values (for example a value expressed as "Minus .4 Degrees Fahrenheit").

Several 4L listings in this set are labeled "cool & heat" or "dual-temperature." They use thermoelectric technology and are described as cooling roughly 15–20°C below ambient and heating up to about 55–65°C in the product details.

Certification statements vary across listings: some list "No Certifications," while others note approvals such as cETL / CETLus. Eco-related claims commonly emphasize thermoelectric operation and wording like "100% Freon-Free" or being free from CFCs and refrigerants.
