Practical limits

The unit accepts AC 100-240V at 50-60Hz, so it works on mains supplies worldwide without a voltage converter. Output is fixed at 19.5V 2.31A, so it cannot charge devices that need a different voltage, a higher current or a USB-C Power Delivery profile.

A two-piece corded design lets you replace the AC cable separately if the plug style or length needs changing, while the fixed DC barrel plug ensures a secure fit on supported HP ports.
