No product in this selection is listed as having a built-in rechargeable battery, so none is a truly battery-powered mini fridge. These compact 4-liter models are portable alternatives that need an external power source: some support a 12V car outlet, and others offer AC/DC or USB power options. The CROWNFUL is best for cooling and warming, Antarctic Star models suit car and home use, Cooluli adds a USB option, and FANSEXPERT includes a lighted mirror.

CROWNFUL 4L Mini Fridge
The CROWNFUL is best for buyers who want a small cooler that can also warm contents. Its 4-liter interior is sized for up to six 12-ounce cans, and a removable shelf helps organize smaller items such as cosmetics or snacks. The carry handle supports portability between a room, office, or trip.
The listed cooling performance is 10–20°C below the surrounding temperature, while warming can reach 149°F (65°C). This makes the product more versatile than a cooling-only option. Limitation: the supplied product details do not specify a battery or power-input type, so confirm the power arrangements before buying for a car or off-grid use.
Antarctic Star 4L Mini Fridge, Black
Choose the black Antarctic Star if you need a compact refrigerator with clearly listed home and vehicle power options. It accepts 100–120V household power or a 12V car power supply, making it useful for plug-in travel. The 4-liter capacity holds up to six 12-ounce cans, and the removable shelf allows more flexible storage for smaller items.
Its listed dimensions are 9.65 inches deep, 7.09 inches wide, and 10.24 inches high. It is best for people who can connect to a compatible power outlet, not for use without an external source. Limitation: a 12V car connection is not the same as an internal battery; the provided features do not list battery operation.
Cooluli Classic 4L With USB Option
The Cooluli is best for buyers who want multiple ways to power a portable cooler. Its listed options include AC/DC and an exclusive USB option. It weighs 4 pounds, measures 7.25 by 10.25 by 10.75 inches externally, and has a 4-liter capacity. The product is described for storing food, drinks, skincare, and other personal items.
Its lightweight construction makes it easier to move between a desk, bedroom, or vehicle than a larger refrigerator. Limitation: a USB power option does not establish that the unit contains a rechargeable battery. Check the product details for the required power source and cable before relying on it away from an outlet.
FANSEXPERT 4L Fridge With LED Mirror
The FANSEXPERT is best for a vanity, dorm desk, or skincare station. Its mirror door has touchscreen lighting with three brightness levels, and its 4-liter interior holds up to six 12-ounce cans. An adjustable shelf accommodates different item sizes, while the carrying handle supports moving it between locations.
The listed power type is AC/DC, and the unit offers cooling and heating modes. Cooling is stated as 27–36°F below ambient temperature; heating reaches 113–140°F, with results varying by surroundings. Limitation: it has no listed built-in battery, and the LED mirror adds a feature that may be unnecessary if your main goal is portable food cooling.
Antarctic Star 4L Mini Fridge, White
This white Antarctic Star model is best for buyers who want the same compact, dual-input setup as the black version in a different color. It supports 100–120V home power and a 12V car power supply. The 4-liter capacity is listed for up to six 12-ounce cans, and its removable shelf can be taken out to make room for different small items.
It is a practical option for a bedroom, office, dorm, or vehicle when the appropriate external power connection is available. Limitation: the listed AC/DC inputs do not mean the refrigerator runs independently; no internal battery is specified in the product features.
Buying Guide: What to Check Before You Buy
Do you need a true battery-powered mini fridge?
Check for an explicitly stated built-in rechargeable battery and battery runtime. None of the five products above lists either. A 12V car input means the unit can draw power from a compatible vehicle outlet; it does not mean the fridge includes a battery. Likewise, a USB power option is not proof of battery operation.
Where will you use the fridge?
For a car, prioritize a model whose details specifically list 12V input, such as either Antarctic Star version. For a desk or bedroom, consider whether AC power is more convenient. For locations without a suitable outlet, these products may not meet the need unless you provide a compatible external power source. Verify required cables and adapters before purchase.
How much space do you need?
Each option is around 4 liters, with several listed for up to six 12-ounce cans. Removable or adjustable shelves can make it easier to fit small containers, skincare products, or snacks, but the compact capacity is not suited to storing a large grocery supply. Compare interior dimensions with the items you plan to store.
Is cooling performance enough?
Thermoelectric-style cooling specifications may be expressed relative to ambient temperature, so performance depends on the surrounding conditions. The CROWNFUL and FANSEXPERT also list warming modes. Choose a cooling-and-warming model only if you have a use for both settings.
Frequently Asked Questions
Are any of these mini fridges battery powered?
No built-in battery is listed for any of the five products. They require an external power source.
Can I use a 12V mini fridge in a car?
The Antarctic Star models list a 12V car power option. Confirm that the required connection and power supply are suitable for your vehicle.
Does USB power mean a fridge is cordless?
No. USB is a way to receive external power, not evidence of a built-in battery. The Cooluli listing mentions a USB option but does not state battery operation.
Can these models keep food cold without power?
The provided product details do not specify cold-storage performance after unplugging. Do not assume they will maintain temperature without power.
Which option has a makeup mirror?
The FANSEXPERT model has a mirror door with touchscreen LED lighting and three brightness levels.
