HP Workstations implementation and recommended use
The charging port on select HP Workstations can supply up to 1.5A. It also supports the USB BC 1.2* specication as well
as the Chinese Telecommunications Industry Standard YD/T 1591-2009. It is recommended to use this port with devices
that support battery charging (typically portable devices like cell phones and tablets)*. It is a safe and ecient charging
solution, that provides more current and better over-current protection than a general USB port. Devices are able to
talk to the on-board charger and select a suitable charging mode and current based on real application needs through a
common communication protocol.
