10 Best Backup Power Supply For Refrigerator 2025 in the United States

The EF ECOFLOW Portable Power Station DELTA 2 stands out as a robust backup power supply with a high capacity of 1024Wh and an impressive output of 1800W. This means it can easily handle the power needs of most refrigerators and other household appliances. One of its biggest strengths is the fast recharge time; it can reach 80% capacity in just 50 minutes and full capacity in 80 minutes using a standard wall outlet, which is ideal for emergencies. Additionally, it supports solar charging, making it a green option for those who prefer renewable energy sources.

The expandable capacity from 1kWh to 3kWh allows for flexibility depending on your needs, whether you're using it at home, camping, or in an RV. Safety is well-covered with its LiFePO4 battery, which has a long lifespan of over 3000 cycles and includes a sophisticated Battery Management System (BMS) for auto-regulation. Portability is another plus, with a manageable weight of 27 pounds and compact dimensions, although it might still be a bit heavy for some users to carry around frequently.

While it offers numerous outlets (15 in total), the higher price point could be a consideration for budget-conscious buyers. The solar panels needed for green charging are optional and sold separately, which can add to the overall cost. This power station is a strong choice for those looking for a reliable, quick-charging, and versatile backup power solution, especially for keeping refrigerators running during outages.

The Jackery Portable Power Station Explorer 500 is a versatile power supply option, ideally suited for outdoor activities and emergency home backup scenarios. This unit has a power capacity of 518Wh and delivers an output wattage of 500W (with a 1000W peak), making it suitable for powering small appliances like a refrigerator temporarily. The lithium-ion battery pack in the unit ensures long-lasting performance and offers the advantage of being lightweight and portable, weighing in at just 13.3 pounds.

It comes with various outlets, including one AC outlet, three USB-A ports, two DC ports, and a car port, offering flexibility in powering different devices simultaneously. The battery management system enhances the efficiency and longevity of the battery, and the pass-through charging feature is a convenient addition, allowing the unit to be used while it is being recharged. Safety features such as low noise levels, no fumes, and low maintenance make it a practical and user-friendly choice. Portability is another strong point, thanks to its compact size and solid handle.

In summary, the Jackery Explorer 500 is a reliable, portable power station that is best suited for short-term power needs and outdoor adventures, but may fall short if you require a prolonged power supply for a refrigerator during a longer power outage.
