What impact does an eGPU have on your Windows laptop's battery life?

2 eGPU Power Draw

An eGPU draws power separately from your laptop's internal components, typically through its own dedicated power supply. However, when connected to your laptop, it can affect the integrated battery's discharge rate. The laptop may increase its power draw to maintain the connection and data transfer with the eGPU, leading to a quicker depletion of the battery when not connected to an external power source.

5 Usage Scenarios

Your usage scenario is a key factor in how an eGPU will affect your laptop's battery life. If you're using the eGPU for tasks that are not graphics-intensive, such as browsing or office applications, the battery impact may be minimal. However, for graphics-heavy tasks like video editing or gaming, the laptop will need to work harder to communicate with the eGPU, leading to faster battery drain.

6 External Power

Lastly, it's important to remember that most eGPUs are designed to be used with an external power source. This means that while they will significantly enhance your laptop's graphics capabilities, they are not intended for on-the-go use where no power outlet is available. For the best experience, use your eGPU when you have access to external power to avoid depleting your laptop's battery.
