Can a Portable Power Station Run a Computer

A computer is an integral part of modern life, serving various purposes in our homes. Even when off-grid you may still need to use a computer to access information, work or access remote services. A power station allows you to run device without the need for Grid power as it stores power from solar panels to use without the need to be plugged in.  Can a portable power station run a computer? Yes, it can.

A 500 Watt Portable Power Station can run a 200 Watt Computer for Two hours. This can increase to up to 4 hours with a 200-watt solar panel plugged in.

How to Choose a Portable power station for computer?

The most important factor in choosing the right portable power station for your computer power is to match the wattage of your computer and the portable power station’s inverter. Older models used up to 300 watts and the new high-performance desktop computer use around 200 watts of power.

An inverter converts the DC power from the battery to AC power that your computer can use. You will need a minimum of 300-watt inverter in order to run your computer. You can go up to 500 watts with your inverter to support other appliances like a blender on the power station.

The battery will easily support these other appliances with no issues however this might reduce the amount of time it will take.

How Long Will a 500-Watt Portable power station Run a 200-Watt Computer?

The second thing to look at when choosing a portable power station is the capacity. Electrical energy is measured in Watt-Hours. This will determine how long the portable power station will run the computer. 

To calculate Watt-Hours you multiply the Wattage of the device or appliance and multiply by the number of hours you use the device.

Watt-Hours = Watts X Hours

If you want to use a computer for 1 hour, you will need 200 Wh of energy or 200-watts of power per hour.

So this will help us determine how long a 500-watt portable power station will run the computer.

To calculate the running time of a desktop computer, you would use the following formula:

Running Time = Portable power station Watt-hours/operating power of the device 

For example to get the running time for a 200-watt desktop computer

= (500*0.85)/200 

= 2.125 hrs

500 Watt-hours is enough to run the desktop computer for around 2 hours and 7 minutes.

How Long will a 500-watt Power Station Last with a 200-watt Solar Panel?

Portable Power Stations can charged with Solar Panels. With a fast recharge rate that can support pass through charging the solar panels adds onto the capacity allowing you to run your appliances for longer. This setup is what is referred to as a solar generator as you using power generated from the sun.

A 200-watt Solar panel can charge a 500Wh power station in around three hours. This will depend on the availability of sunlight. 3 hours of sunlight in an ideal situation should provide 600Wh enough to fully recharge the solar generator.

With this extra power from the solar panel going into the battery you can double the running time for your computer and run it up to 4 hours.


In conclusion, the integration of a portable power station into our off-grid home for running appliances is a practical and sustainable solution. Matching the wattage of the computer with the power station’s inverter, as well as factoring in the watt-hours capacity, enables users to make informed decisions about the suitability of their chosen power station for their computing needs.
