AC adapter HP 65W model 753178-001 nPFC — 65W laptop power supply

AC adapter HP 65W model 753178-001 nPFC — 65W laptop power supply delivers regulated DC output to charge and power compatible HP notebooks. The adapter converts AC mains to a stable low-voltage DC supply and includes active power factor correction (nPFC) to improve conversion efficiency and reduce harmonic distortion. It is intended as a direct replacement for an original HP 65W adapter when the original unit is lost, damaged or no longer reliable.

Advantages

This 65W AC adapter provides consistent voltage and current for reliable laptop operation and charging. The integrated nPFC circuitry reduces power losses and helps maintain more stable operation under varying mains conditions. The compact form factor and standard connector make it suitable for both mobile use and stationary setups, while built-in protection features help guard against overcurrent, overvoltage and short circuits.

Suitable for

• Replacing a lost or broken HP 65W laptop adapter
• Carrying as a spare adapter for travel and mobile work
• Using at a desk or workstation to power and charge compatible HP notebooks
• Temporary replacement during repair or maintenance of the original adapter

Key specifications
