Antarctic Star 4L Mini Fridge — Portable Personal Cooler (Black), AC/DC Dual-Power, Quiet Thermoelectric Cooling

The Antarctic Star 4L portable mini fridge is a compact, dual-power cooler that chills up to six 12 oz cans or stores skincare and snacks while running quietly on AC or DC power.

This personal refrigerator blends compact dimensions with flexible cooling to suit bedrooms, offices, dorms, cars and small travel setups. Using thermoelectric (semiconductor) cooling, it lowers internal temperature below ambient without refrigerant, keeping sound levels low and energy use modest. The removable interior shelf and the small footprint make it easy to fit on a desk, nightstand or car seat while still holding breast milk, cosmetic products, chilled beverages and light food items.

How cold will this mini fridge get and how fast?

The unit reduces temperature below surrounding air by roughly 12–18°C (about 21–32°F) within the first one to two hours depending on ambient conditions. Typical operating range can reach as low as approximately 32°F–59°F (0–15°C) for cooler environments, but exact values vary with room temperature and load.

• Thermoelectric cooling—no freon refrigerant used.
• Average cool-down: 1–2 hours to reach target delta from ambient.
• Best performance in moderate room temperatures and with some pre-chilled items.

What power options does it offer for home and travel?

This mini fridge accepts both 120V AC for indoor use and 12V DC for in-vehicle operation, so you can plug it into household outlets or a car adapter for road trips. The dual-power capability makes it convenient for commuting, camping, long drives or moving between rooms.

• Includes AC adapter for standard home outlets.
• Includes DC cable for car cigarette lighter sockets (12V).
• Low electrical draw suited for extended use without heavy power demands.

How much can it hold and how is the interior organized?

The fridge offers 4 liters of storage space—enough for six 12-ounce cans laid upright—and an adjustable shelf that creates two levels for small bottles, skincare jars or food containers. Its compact outer dimensions let it fit into tight spaces while the removable inner shelf increases versatility for taller items.

• Capacity: holds up to six 12 oz cans (4 L total).
• External size: about 9.65" deep × 7.09" wide × 10.24" high.
• Inner compartment with removable shelf for flexible storage arrangements.

Is it quiet and energy-conscious for overnight use?

The thermoelectric design minimizes vibration and mechanical noise, producing a low sound level suitable for bedrooms and offices. It consumes significantly less power than full-size compressors, making it a practical choice for continuous daytime or overnight use when storing cosmetics, medicines that don’t require strict refrigeration, or drinks.

• Quiet operation—built for low noise in living spaces.
• Environmentally friendlier cooling without refrigerants.
• Energy-efficient for small, dedicated cooling needs.

Who is this for? The Antarctic Star 4L portable mini fridge is designed for people who need a small, flexible cooler: students in dorms, professionals who want chilled drinks or skincare at their desk, road trippers who need a car-powered cooler, or anyone with limited space seeking dedicated storage for breast milk, cosmetics or snacks. It’s best when used for short-term chilled storage rather than long-term deep refrigeration of perishable foods.
