It was originally written for the XBox One controller since Microsoft dropped all visual hints for low battery, but it should work with any gamepad that can be addressed via XInput (which should be all controllers that work in XBox-controller-enabled games).

Controllers reported as working/being recognized so far:
  • XBOne + dongle
  • XBOne Elite + dongle
  • XBOne S + dongle
  • XBOne S + Bluetooth
  • XB360
