Overview
A 4-liter thermoelectric mini fridge/warmer that runs on AC, 12V DC or USB power, sized for a desk, dorm or vanity. Cools by a fixed number of degrees below room temperature rather than to a set target, and switches to warming with one control.
Because it's thermoelectric, not compressor-based, the cooling is relative to ambient temperature - one reviewer measured roughly a 38-40F drop on AC or DC power and a smaller drop on USB power, so results vary with the power source and the room. This makes it well suited to drinks and skincare, but a critical review says it isn't reliable enough to trust with food that needs consistent cold storage.
- 4-liter cooling/warming capacity
- AC + DC + USB power included
- 40-45F below ambient cooling
- 122-144F warming range
Who it's for
Suits desk, dorm or vanity storage of drinks, snacks or skincare products in small quantities. Not a substitute for a real refrigerator when food safety depends on a consistent, guaranteed-cold temperature.
Pros and cons
- Quiet thermoelectric operation
- AC, DC and USB power options
- Compact enough for a desk or vanity
- Doubles as a warmer with one switch
- Cooling is relative to room temperature, not fixed
- Needs fan clearance or runs warm
- Not reliable for food needing consistent cold storage
- Small 4-liter capacity
Performance notes
A semiconductor thermoelectric module cools 40 to 45 degrees F below ambient temperature and can be switched to warm up to 122-144F with the same control. Performance depends on power source and airflow: one reviewer measured about a 38-40F drop on AC or 12V DC power versus roughly 24F on USB power, and several note the fan side needs clearance or the unit runs warm.
