10 Best Most Energy Efficient Mini Fridge 2025 in the United States

The Upstreman 3.2 Cu.Ft Mini Fridge with Freezer is a compact and energy-efficient solution suitable for dorm rooms, offices, bedrooms, and small living spaces. With a 5-star Energy Star rating and an estimated energy consumption of 206 kWh per year, this mini fridge is designed to be both environmentally friendly and cost-effective. Its quiet operation at 38 dB ensures it won't be a disturbance in quiet environments like bedrooms or studies.

The fridge's single-door design maximizes storage space, providing more room compared to similar-sized double-door models. The adjustable thermostat offers five temperature settings, allowing users to customize cooling needs for various perishable items. However, the freezer compartment may not be suitable for storing ice cream due to its temperature range. The manual defrost system requires occasional maintenance, which might be less convenient for some users.

The fridge includes practical features like a crisper drawer for fruits and vegetables and removable shelves for flexible storage options. The reversible door and adjustable legs add to its versatility in different settings. While the fridge performs well in energy efficiency and noise levels, potential buyers should consider the manual defrost requirement and the freezer's limited suitability for certain frozen goods as minor drawbacks. This mini fridge is an excellent choice for those prioritizing energy efficiency and quiet operation in a compact form factor.

The BANGSON 4.0 Cu.Ft Small Refrigerator with Bottom Freezer is a practical choice for those needing a compact yet spacious fridge for apartments, dorms, or offices. Its tall, slim design occupies just over 2 square feet but offers a decent 4 cubic feet capacity, including a 1.27 Cu.Ft freezer compartment. This allows you to store a variety of foods and keep them fresh thanks to adjustable temperature controls, ranging from freezing to refrigeration modes. The manual defrost system is simple but requires occasional maintenance. Noise levels are low at about 39 dB, making it suitable for quiet environments like bedrooms or studies.

The product highlights efficient refrigeration technology and a well-insulated cabinet. Additional thoughtful touches like reversible doors, LED lighting, adjustable shelves, and easy-to-clean door seals add convenience. For users who want a reliable, quiet, and moderately energy-conscious mini fridge with a freezer, this model offers good value and flexibility.

The DEMULLER 2.4 Cu.ft Mini Fridge is a compact, double-door refrigerator designed for small spaces like dorm rooms, offices, or apartments. Its 2.4 cubic feet capacity is split between a 0.8 cubic feet freezer and a 1.6 cubic feet fridge area, making it convenient for storing both frozen and fresh items. The seven-level adjustable thermostat allows you to set temperatures from just below freezing (-0.4 ℉) up to 50 ℉, giving good control over food freshness. It uses an advanced compressor that cools efficiently and quietly, operating at around 38 dB, so it won’t be noisy during use. The fridge measures about 15 x 15 x 31 inches, which is easy to fit almost anywhere.

This model uses manual defrost, which means you’ll need to periodically remove ice buildup yourself, unlike some fridges with automatic defrost. The compact design and retro black finish add style without sacrificing function. If you want a small fridge with a separate freezer compartment that can be quietly adjusted to your cooling needs, this model is a solid choice. It might not be the absolute top performer in energy savings compared to some other models.
