Buying Guide: What to Look for in 2026
- Compressor vs. Thermoelectric: Compressor fridges (like the RCA) are much colder and more reliable for food. Thermoelectric (like AstroAI) is better for drinks and skincare as they are lighter and quieter.
- Size & Clearance: Always measure your space. Most mini fridges need at least 2-4 inches of “breathing room” on the sides to prevent the motor from overheating.
- Noise (Decibels): If placing it in a bedroom, look for units under 40dB. Anything above 45dB might sound like a constant hum in a quiet room.
Frequently Asked Questions (FAQ)
Q: Can a mini fridge be kept on carpet?
A: It’s not recommended as carpets trap heat. If you must, use a “fridge mat” or a piece of plywood underneath.
Q: How long do mini geladeiras last?
A: A high-quality compressor model can last 8-10 years, while thermoelectric models typically last 3-5 years.
Q: Are they expensive to run?
A: Energy Star models usually cost between $25 and $40 per year in electricity.
Q: Can I store raw meat in a thermoelectric fridge?
A: No. Thermoelectric fridges are meant for chilling drinks or keeping products cool. For raw meat or milk, always use a compressor-based fridge.
Q: Why is there ice buildup in the back?
A: This is usually due to moisture or setting the thermostat too low. Regular manual defrosting (once every few months) is necessary.
