I know that there is a library in .NET Framework called System.Windows.Forms that includes SystemInformation.PowerStatus but is there an equivalent to this in .NET Core? I don't want to have to change my project to .NET Framework to do it so I was curious if there is a way to do it in .NET Core

Looking at the .NET Reference Source, the SystemInformation.PowerStatus class is just a wrapper around a call to the Win32 function GetSystemPowerStatus[^].

[DllImport("kernel32.dll", ExactSpelling=true, CharSet=CharSet.Auto)]
        [ResourceExposure(ResourceScope.None)]
        public static extern bool GetSystemPowerStatus([In, Out] ref NativeMethods.SYSTEM_POWER_STATUS systemPowerStatus);

Dave, OP is looking for .Net Core code. WinAPI is for Windows only. ;)

I'm busy as hell right now, so I just provided what the reference source was using while waiting for a deployment to finish. That should be a decent start for further research.

According to the documentation, the PowerStatus class is still available in .NET Core 3.0 or later:
PowerStatus Class (System.Windows.Forms) | Microsoft Docs[^]
PowerStatus - .NET API Catalog[^]

This looks promising: GitHub - dalihub/TizenFX: TizenFX API, which allows you to access platform-specific features not covered by the generic .NET and Xamarin.Forms features, such as system information and status, battery status, sensor date, and account and connectivity [^]
