Overview

The Koolatron KRT04-P is a 4 liter thermoelectric mini fridge that holds six 12 oz cans, running on either a 110V wall outlet or a 12V car outlet. It cools only, dropping to about 32°F below room temperature, and suits a nightstand, desk, or dorm shelf rather than a kitchen.

  • 4 liter capacity, holds six 12 oz cans
  • Runs on 110V AC at home or 12V DC in a vehicle
  • Thermoelectric cooling reaches about 32°F below room temperature
  • Twist-to-open door latch with retractable carry handle

Who it's for

Fits anyone who wants a few cold cans or a stash of cold skincare within arm's reach at a desk, bedside, or bathroom counter. It is not built to chill perishable food safely or to serve as a household fridge.

What buyers say

From Amazon customer reviews.

Reviewers who love it use it for chilled skincare, drinks, or coffee creamer and describe it as quiet and fast to cool. The recurring complaint is early failure, with several units stopping work between 3 and 6 months in, though buyers who contacted Koolatron report the company replacing units under warranty.
