Best Battery Backup For Computer

When deciding on the battery backup system for a PC, you need to evaluate how much power you require. Additionally, you must understand how long you want to power the appliances. This is because you may need a larger capacity power station to charge a high-power-consuming device for long hours. Once you have calculated the wattage consumption of your device, you can choose a battery backup or power station that supplies the same or more than the power required.

Computer Watts

Depending on the model, an average desktop computer consumes nearly 60 to 300 watts of power. For example, if you use a 60 watts computer for 4 hours, the daily power required will be 60W*4H = 240Wh.

Remember, this is a general estimation, and the power needs may vary depending on the watt consumption of the computer and the number of hours you use it. Based on your power needs, you can find the best battery backup for computers from the below-mentioned list.

How To Choose The Best Battery Backup For A Computer?

Unexpected power outages when you’re working from home or no availability of an electrical outlet when you’re working on an outdoor trip can leave your computer without power. A robust and efficient battery backup system will provide the necessary power to your devices when and wherever required.

However, when choosing the best battery backup for a computer, there are several factors to consider. Below we will elaborate on each aspect so you can select the ideal battery backup for your home or work appliances.


Battery capacity typically refers to how much power the battery backup system can supply and for how long. It is generally measured in watt-hours or Wh. Even though the exact battery capacity you require for your appliance will depend on its power requirement, it’s a wise idea to opt for a high-capacity battery backup system. Not only will it help you recharge your computer during RV trips, camping, or long-term power outages, but it will also provide power to other gadgets.

Inverter for Surge Protector

Most home or outdoor appliances require alternating currents to function. However, solar panels or other charging solutions produce direct current initially. An inverter is a critical device that converts direct current (DC) to alternating current (AC), so you can power devices. While some battery backup systems have a built-in inverter to avoid power surges and spikes, others do not. Therefore, always choose a battery backup system with a built-in inverter for surge protection. A battery backup surge protector for computers will ensure a stable electricity supply.

Battery Life

Battery life is another crucial thing to keep in mind. Jackery’s ultimate power solution comes with a long battery life. The Jackery Explorer 3000 Pro Portable Power Station is a top-notch solar charging solution that performs its best up to 2000 cycles. After that, the battery’s lifespan slightly declines, and you can expect 70%+ of your original capacity. It’s worth noting that little degradation in performance is normal as the battery ages.

Input/Output Ports

The number and type of appliances a battery backup system can recharge will depend on the input and output ports available. For instance, Jackery power stations feature multiple output ports, so you can charge all outdoor devices with your computer. In addition, the power stations come with various input ports, helping to recharge the battery in different ways. For example, you can use Jackery SolarSaga Solar Panels, wall, or car charging to recharge the power stations once they are depleted.


Computers, laptops, smartphones, etc., are critical gadgets that will stop working when charged using an unsafe battery backup system. Therefore, you need to choose a battery backup for a computer that has robust safety features such as overvoltage protection, overload protection, temperature sensors, and short circuit protection. Jackery Explorer Portable Power Stations have in-built safety features like temperature sensors, overvoltage protection, overload protection, etc., to ensure safe supply to all appliances.  


Weight can be a crucial factor to remember while searching for a battery backup, especially if you want to take it on outdoor trips. Some high-power battery backups can be heavier than others. Hence, it becomes daunting to choose the one that fits your power requirements and is lightweight. All the Jackery power stations are designed to be portable and light in weight. The easy-to-carry handle ensures you can quickly move the power station from one place to another.


Battery backups can range from a few hundred dollars to thousands. However, what matters is the quality of materials used in manufacturing. Jackery offers affordable and feature-rich solar generators and power stations. You can purchase a battery backup depending on your power requirements and budget from the different sizes available.

Easy to Use

Not all battery backups are easy to use. While some batteries can be easily used with a simple press and play button, others require high technical knowledge. Jackery Solar Generators are easy to use, with a clean interface and display screen. Using the solar cable, you can connect the power station to the solar panels and start charging your devices.  

FAQs About Battery Backup For Computer

1. How to install a battery backup for a computer?

Installing a battery backup for a computer is extremely easy if you are using Jackery Solar Generator. These solar generators consist of Jackery Explorer Portable Power Station and SolarSaga Solar Panels. Below are the three simple steps you need to follow to set up the solar system and start charging your appliances.

Step 1: Connect the solar panels to the power station using the solar charging cable.

Step 2: Let the power station charge and store the power produced by the solar panels.

Step 3: Once the backup battery has enough power, you can start charging the appliances. You can use a solar cable to connect the computer to the power station for charging.

2. What size battery backup for a computer?

The ideal size battery backup for a computer will depend on the device’s power requirements. For instance, if the PC consumes around 100 watts of power, you can charge it using a small portable power station.

Here is an example to understand better. Suppose you use Jackery Solar Generator 1000 Pro to charge 100W of the computer.

Working Time = Capacity in Wh × 0.85 / 100W = 1002Wh × 0.85 / 100W = 8.5 hours.

3. Is battery backup worth it for a PC?

In short, yes. Unexpected power outages, brownouts, blackouts, etc., can halt your work. That’s where a battery backup system for computers comes into the picture. It allows you to efficiently charge your laptop whenever you are away from the electricity grid or when it is down. The best part about having a robust battery backup system is that you can charge multiple other devices, like microwaves, refrigerators, coffee makers, etc.

4. How long does a PC backup battery last?

Any PC battery backup system can last for a few minutes to hours, depending on its battery capacity and how much power your computer consumes.


Choosing a battery backup for computers ensures uninterrupted productivity and helps you stay connected, regardless of where you are. However, there are hundreds of computer battery backups available in the market. The key to choosing the best battery backup is analyzing how much power you need.

Jackery Solar Generators are available in different sizes, and you can choose the ideal size depending on your needs. For instance, you can consider how long you need the battery backup to last and the number of appliances you want to power.

If you are looking for a power station that supplies electricity to a computer, consider Jackery Solar Generator 1000 Pro. Alternatively, if you want to power all work-related devices or outdoor appliances with your computer, trust Jackery Solar Generator 3000 Pro.
