Top-10 Backup Power Supply For Refrigerator
Loved in the USA

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 300 is a versatile and lightweight backup power supply option, especially useful for situations like camping, travel, and power outages. It has a power capacity of 293Wh and can deliver up to 300 watts of stable power, making it suitable to keep smaller appliances like a refrigerator running for a limited time. Its standout feature is the quick recharge capability, where it can reach 80% charge in just 2 hours through a wall outlet combined with the USB-C port. Additionally, it supports solar charging, which is a great option for extended outdoor use.

The device is also equipped with multiple ports, which means you can power several devices simultaneously, from laptops to cameras. Weighing just 7.1 pounds, it is highly portable and easy to carry around. The safety features, including Pure Sine Wave AC outlets, ensure that your devices are protected from power surges.

One notable limitation is the relatively short runtime of about 5 hours under moderate use. This might not be sufficient for longer outages without recharging. Furthermore, while it’s a great portable option, its power capacity may not be enough for larger refrigerators or extended periods without access to recharging options. If you are looking for an emergency backup power supply for short-term needs or outdoor activities, the Jackery Explorer 300 is a reliable and convenient choice.

The EF ECOFLOW DELTA Pro Extra Battery 3600Wh offers a robust solution for backing up your refrigerator during power outages. With a high power capacity of up to 3600 watts and expandable up to 7200Wh with an extra battery, this unit can easily support essential appliances for extended periods.

The battery type is long-lasting LFP (Lithium Iron Phosphate), which is known for its durability and safety. The device boasts a fast recharge time of 2.7 hours, ensuring you can get back up and running quickly during emergencies. Additionally, it supports multiple charging methods, enhancing its versatility for use in various situations, including home use, camping, and RVs.

Its portability might be an issue due to its weight of 105 pounds, making it less convenient to move around frequently. Safety features are robust, with clean and safe power delivery and smart control via the EcoFlow app, allowing remote monitoring and management. The LCD screen also provides real-time information on output, input, remaining charge, and time remaining. Despite its hefty size and weight posing a challenge for users needing a more portable solution, it remains a strong contender for reliable and efficient backup power supply for your refrigerator during blackouts or other emergencies.
