About Cooluli
Cooluli was founded in 2016 in Brooklyn, NY, with a stated mission to fill the need for high-end, portable cooling systems. The company's lineup runs from its original 4-liter Classic cooler-warmer up through larger Concord and Curve models, plus skincare-focused Glow and Beauty units with built-in mirrors and LED lighting — all built around the brand's own EcoMax™ thermoelectric technology, which it markets as running without compressors, cryogens, refrigerants, or Freon.
Cooluli's press coverage extends well beyond Amazon, with its mini fridges featured in Allure, BuzzFeed, Delish, Food & Wine, Her Campus, The Strategist, and US Weekly. The company's Classic 4L cooler-warmer has also become one of the most-reviewed compact thermoelectric fridges on Amazon, a track record it has built on dual cooling-and-warming functionality and flexible USB, AC, and 12V power options.

Why we recognized Cooluli
The DeskRated Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our hands-on category reviews.

Cooluli products we rated highly
Cooluli Classic 4L Portable Mini Fridge
In our testing, this is the most reviewed desk cube in the category by a wide margin, backed by a 28,000-plus-review track record for reliability. A single switch handles both cooling and warming, so it covers chilled drinks and a warm lunch from the same unit, and USB, AC, and 12V power options make it the most flexible model to move between a desk, a car, and a home office. The thermoelectric cooling runs as a quiet continuous hum rather than a cycling compressor, so there's no sudden on/off noise to break concentration.
