Fine for chilling a few cans below room temperature at a desk, but it won't reach true refrigerator temperatures and the printed logo and AC adapter are the weak points reported.

Overview
A 6 can thermoelectric mini fridge with Coca-Cola Zero branding, built to run on either a wall outlet or a 12V vehicle plug. It cools below room temperature rather than to a fixed set point, and can also switch to a warming mode.
This is a novelty-sized cooler more than a true refrigerator: thermoelectric units like this one cool relative to ambient temperature, up to 32 degrees F below room temp per the listing, instead of hitting an absolute target like 38 degrees F, which matters if you expect refrigerator-cold drinks in a hot room. Reviewers who use it for a handful of cans on a desk or in a dorm are satisfied; anyone expecting compressor-fridge performance is not.
- Holds 6 standard cans
- Dual 12V DC / 110V AC power
- Cools up to 32 degrees F below room temperature
- Warm mode heats up to 135 degrees F
Who it's for
Desk or dorm use for keeping a few cans cooler than room temperature, not a replacement for a real refrigerator. Good for someone who wants to avoid a shared break room fridge for a handful of drinks.
What buyers say
From Amazon customer reviews.
Reviewers who use it for a handful of cans at a desk or in a dorm are happy with the size and quiet operation, including one who uses it specifically to avoid a shared office fridge. The complaints cluster around durability: the Coca-Cola logo sticker peeling off within a few weeks, an AC adapter dying in under a year, and one reviewer who felt it never got meaningfully cold and was told to pay for repairs after it stopped working.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs on both wall power and a 12V vehicle outlet
- Quiet enough for a desk or bedroom
- Compact 6 can size fits small spaces
- Can switch to a warming mode as well
- Coca-Cola logo sticker reported peeling within weeks
- Does not reach true refrigerator-cold temperatures
- AC adapter failures reported within the first year
Performance notes
It uses thermoelectric cooling rather than a compressor, which is quieter but pulls the interior down relative to room temperature instead of to a fixed cold setting, so results vary with where it sits. Several reviewers confirm it reliably chills six cans for desk use, but one reviewer measured it barely cooler than sitting outside in fall weather and considered it closer to a cooler than a fridge.
