Chicony 65W AC Adapter for HP ProBook 650 G1

This 65-watt power supply delivers 19 volts at 3.42 amps and matches the 7.4 by 5.0 millimetre barrel tip used by the HP ProBook 650 G1. It also replaces the 18.5-volt 3.5-amp variant, so one unit covers both specifications. The package includes a US mains cable for immediate use.

UL Safety Tested Build with Fixed Barrel Connector

The adapter carries UL safety certification, confirming it meets recognised electrical safety standards. A fixed 7.4 by 5.0 millimetre barrel connector removes the need for interchangeable tips and reduces wear from repeated insertion. The integrated cable strain relief supports daily connect and disconnect cycles without damaging the wire entry point.

Efficient 65W Operation for Compatible Notebooks

At 65 watts the unit runs cool during typical office workloads and charges the battery while the system is in use. The sealed enclosure has no moving parts, so operation remains silent in quiet environments. Power draw scales with the laptop's demand, avoiding unnecessary heat when the battery is full or the system is idle.
