Top 5 Best Battery Backups For Refrigerators

A power outage is an unpredictable situation that can happen at any time. When it occurs, the loss of power causes the fridge to stop cooling after a few hours.

Thus, it poses the risk of your edibles getting spoiled. If your refrigerator is fully stocked, what a waste it would be.

Fortunately, you can avoid this distress by powering your refrigerator with suitable alternatives.

While a common alternative is using generators, a battery backup system is even better. 

Refrigerator backup batteries are a must-have for combating low power or total blackouts. Some backup battery alternatives include the Jackery power station explorer and the Geneverse home power one. However, there are other credible batteries that come in handy at unexpected blackouts.

What to Look Out for in Refrigerator Backup Battery?

To grade a refrigerator battery as useful, it would have to satisfy your needs which primarily involve keeping your fridge cold.

To ensure that a backup battery can function properly, here are things to check before purchasing one.

  • You have to check its wattage as any backup battery system that offers below a thousand wattage is insufficient to carry your refrigerator smoothly.
  • Know the amount of energy your refrigerator requires. You can verify this by multiplying your refrigerator’s voltage and amperes which you will find on a sticker at the handle or in the manual.
  • Ensure that the backup power supply system’s output matches your refrigerator’s plug-in.
  • Look out for battery life and life cycle to ensure that it can last you for an extended period.
  • If you’re shopping online, it will be best for you to check the product’s reviews and ratings.

Best Refrigerator Battery Brands

Doubtlessly, dozens of battery backup power systems are available for purchase online and in stores.

However, it would be a waste to blindly purchase one that won’t render all its claims. Thus, this is the reason you need to know the best brands.

To take the stress off your shoulders, here are the best refrigerator battery brands I recommend.

The first is EF ECOFLOW, an innovative brand that provides excellent eco-friendly power solutions.

Since venturing out in 2017, ECOFLOW has a host of fantastic products, and the portable power station Delta is proof of this.

The second is Geneverse (formerly Generark). The brand was spurred to provide affordable and renewable backup for power emergencies after the founder’s experience.

This urge for innovation led to the creation of the Homepower one. Ideally, even if you have never experienced a power outage, you should have one of the above.

However, if you want an uninterruptible power supply for your desktop and similar devices, you should see the Jackery, APC, or Tripp Lite UPS.

The choice is up to you so go with whatever suits you. And, if you decide to opt for other preferable alternatives, study it to ensure that it’s safe and can power necessary appliances.


The refrigerator is a vital home appliance as it stores food and keeps them fresh. We all know it needs the power to function, but when there’s an outage, the need for suitable alternatives arises.

Luckily, there are refrigerator batteries from trustworthy brands like ECOFLOW, Geneverse, and Blueetti, amongst others.
