Why Do You Need an Emergency Battery Backup Power?

When a power outage hits, the essential appliances like refrigerators, heaters, CPAP machines, etc., in the home stop functioning. Without an emergency battery backup power, food can be spoiled in the fridge. That's why it is necessary to choose an emergency battery backup. Here are some reasons to select the best home emergency battery backup power.

  • Refrigeratorsmaintain a constant temperature so food items don't spoil. Without power, maintaining an appropriate temperature is impossible, and the food kept inside the freezer will spoil. An emergency battery backup source will quickly restore power when the electricity grid is down.
  • For most people, blackouts mean all the lights at home are turned off. Unless you've candles ready, the darkness can impact your lifestyle. A home emergency battery backup can charge lights and lamps for long hours.
  • Your home uses power to maintain a comfortable temperature in summer and winter. The large home battery backup solution can charge space heaters or air conditioners to keep the home comfortable for living.

You can even choose the best phone battery backup emergency power source to charge small appliances like smartphones, laptops, etc.

How Does Emergency Battery Backup Power Work?

The emergency battery backup power works when the solar panels convert the free solar energy into electricity and store it in the battery backup to charge appliances. Jackery manufactures highly efficient solar power systems, including solar generators, solar panels, and power stations. The Jackery Solar Generators consist of Jackery Explorer Portable Power Stations and Jackery SolarSaga Solar Panels.

The Jackery SolarSaga Solar Panels are made with high-quality monocrystalline silicon solar cells that convert the sun's energy into DC electricity. Then, the pure sine wave inverter in the Jackery Explorer Portable Power Stations converts the DC to AC electricity to charge home or outdoor appliances. The Jackery power stations can also be recharged via other methods like wall outlets or car chargers.

How to Choose the Best Emergency Battery Backup Power?

Solar generators are battery-powered generators that can be used as an emergency power backup for home or outdoor devices. While they perform the same function and generate electricity when the main electricity grid is down, not all of them are the same. Some battery backups are designed for outdoor activities, whereas larger solar generators can run multiple power-hungry appliances at home. Now that you know what emergency battery backup power is, let us reveal the factors that help you choose the best emergency solar generators for your needs.


A portable power station can run multiple power-hungry appliances at once. The battery backup capacity will determine how many and what kind of devices you can run. Jackery Solar Generators come in many different sizes and capacities. Naturally, the higher the capacity, the more appliances the power bank will run.

Safe and Clean

Solar generators are quiet and do not produce fumes or heat. They are environment-friendly and require little to no maintenance. Jackery Solar Generators feature safe LiFePO4 or NMC batteries that are quiet and absolutely safe for indoor use. They only generate 30-45dB of noise, meaning you can sleep peacefully with the generator on.

Size and Weight

The emergency battery backup should be easy to carry, so you can put one in an RV or car while camping, RVing, and hiking. Jackery Solar Generators are compact, lightweight, portable charging solutions for outdoor adventures. They even come with robust handles and double wheels, making the solar generator a great choice.

Input/Output Ports

Many advanced power stations come with AC, DC, and USB ports to charge a wide range of appliances like laptops, smartphones, heaters, ACs, etc. Jackery Explorer Portable Power Stations boast several ports, including AC, USB-A, USB-C, and DC ports, to run multiple devices that require different outlets simultaneously.


Generally, the lifespan of the solar generator will depend on what type of battery it has. LiFePO4 and NMC batteries are efficient, quiet, and have a long lifespan. Generally speaking, Jackery Solar Generators featuring LiFePO4 or NMC batteries can last up to 10 years.

Keeping these few factors in mind will help you select the best emergency power source for your indoor or outdoor needs.
