How To Choose The Best Battery Backup For Refrigerator?

Investing in the best battery backup for the refrigerator is essential to cover any dips in the main electricity grid. However, not all battery backups can meet the high power demands of a fridge. In this section, we will focus on the vital factors one must consider while choosing a backup battery.

Battery Capacity

The total amount of power a battery can store is called capacity. Generally speaking, the higher the capacity of a battery, the higher its power output.

If you want to charge a large refrigerator that has high watt consumption, it's better to have one high-capacity battery.

If you are confused about which battery backup to choose, consider Jackery Explorer Portable Power Stations. They feature a high battery capacity that seamlessly powers all home or outdoor appliances.

Recharging Options

The next important factor in choosing the power station is its recharging options. If you want to power the battery backup using the grid, outlet charging is necessary.

Alternatively, those wanting to power the battery using solar panels must ensure the system supports solar charging.

Jackery Explorer Portable Power Stations support three charging options: solar panels, car outlets, and wall outlets. With Jackery, you can rest assured you are prepared for unplanned long-term power outages.

Battery Type

When deciding on the best battery backup for a refrigerator, consider the cost, longevity, safety, etc. Lithium-ion batteries used in Jackery Explorer Portable Power Stations are generally preferable over other types. This is because they have a long lifespan and high depth of discharge.


Battery backups with high capacity are generally heavier than those with less capacity. But that's not the case if you choose Jackery power stations. The high-capacity Jackery battery backup solutions are light in weight and feature a foldable handle for easy carrying.

The higher capacity models like Jackery Explorer 2000 Plus Portable Power Station have wheels and a pull rod, making them easier to carry from one place to another.

Silent Operation

Gas generators are one of the most common charging solutions available. However, they are noisy and emit harmful gases during operation. For this reason, many people opt for solar battery backup systems that produce little to no noise.

Jackery Explorer Portable Power Stations have a low decibel rating, meaning they are quieter than a whisper. You can use them indoors or during your outdoor adventure to charge most of your appliances.

Battery Backup for Refrigerator FAQs

Can a battery backup run a fridge?

Yes. You can plug the refrigerator into the backup battery system and connect it to solar panels or a wall outlet for a power supply.

Jackery Solar Generators combine Explorer Portable Power Stations and SolarSaga Solar Panels to ensure reliable power supply to refrigerators and other appliances.

All you need to do is use the solar cables to connect solar panels to the power station, which is plugged into the refrigerator.

What size battery is needed to run a fridge? How long can a battery generator run a refrigerator?

The size of the battery refrigerator will depend on the type, power consumption, and size of the refrigerator. For example, if you have a larger fridge that consumes more power, you'll need a large-capacity solar generator to keep it powered. Here is an example:

The working hours of Jackery Explorer 2000 Plus Portable Power Station to power a 500W refrigerator can be calculated as follows:

Working Hours = Battery Capacity × 0.85 / Operating wattage of the refrigerator = 2042.8Wh × 0.85 / 500W = 3.4H.

How to prepare your refrigerator for a power outage?

When power outages occur, everything suddenly goes dark and silent. Here are a few ways to be prepared for a power outage.

  • Avoid opening the refrigerator again and again to put in more things as it gradually reduces the time the freezer would have maintained its temperature.
  • Invest in a battery-powered generator or battery refrigeratorthat will supply electricity to the refrigerator when power goes out.
  • Choose a cooler with ice to store perishables if the power outage lasts for over four hours.

How to reduce the energy consumption of your refrigerator?

Below are a few simple ways to help you reduce your refrigerator's energy consumption, save money on electricity bills, and make your home energy-efficient.

  • Locate your fridge in a cooler area of your home and away from the stove and windows.
  • Avoid opening the refrigerator door frequently, as it allows warm air to enter the refrigerator.
  • Do not place the hot containers in the refrigerator. The best practice is to let them cool close to room temperature before refrigerating them.
  • Consider purchasing a solar battery backup like Jackery Explorer Pro Portable Power Stations to reduce reliance on the electricity grid and gas generators.

Final Thoughts

The battery backup for refrigerators helps you to reduce your dependence on the electric grid and prepare against power outages. Jackery Explorer Portable Power Stations offer reliable, eco-friendly energy to power different types of appliances.

Whether you're looking for a solar generator for a refrigerator or a complete home backup solution, Jackery's line of products has something for everyone.
