Update 01.08.2017
I have updated the script to ensure that the Windows.Devices.Power.Battery class is properly loaded, as this wasn’t the case in a PowerShell 64 bit session.
A little script i wrote to retrieve the Battery Charge status. The script makes use of the BatteryReport class that agregates the information should the device have more than one battery like the Surface Book.

I ran this script without error, but also without any output. Where should I expect to view the output?
first run the script to load the function, then run the function itself
This is missing: Get-ExecutionPolicy -List and Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
