Power adapter HP 90W PFC Smart 4.5mm – 90W output, 4.5 mm tip

The HP 90W PFC Smart 4.5mm power adapter (MPN 937520-002, EAN 5706998540881) supplies up to 90 watts of DC power through a 4.5 mm round tip designed for compatible HP notebooks. The adapter integrates power factor correction (PFC) to improve input efficiency and reduce electrical noise. It is intended for charging and powering laptops in home, office or mobile environments and provides regulated output to support stable operation of the connected device.

Advantages

The adapter delivers a defined 90W output suitable for mid- to high-power notebook models while the 4.5 mm tip ensures physical compatibility with supported HP charging ports. Built-in PFC reduces reactive current draw and helps maintain more efficient use of mains power. The adapter's regulated DC output contributes to stable voltage delivery and consistent charging behavior for battery management systems. The product is identified by manufacturer part number 937520-002 and EAN 5706998540881 for accurate replacement matching.

Suitable for

• Charging compatible HP notebooks that accept a 4.5 mm round tip and require up to 90W input
• Replacing an original HP 90W adapter with MPN 937520-002
• Use in home, office, or on-the-go scenarios where a stable 90W DC supply is needed
• Systems where improved input efficiency and reduced electrical noise are desired due to PFC

How to use

Connect the AC input plug of the adapter to a compatible mains outlet and attach the 4.5 mm round tip to the notebook's DC-in socket. Ensure the connection is secure and that the notebook indicates charging or external power. Use the adapter in environments within the device manufacturer's recommended ambient temperature and avoid exposing it to moisture. Disconnect the adapter from the mains before unplugging the DC tip when necessary.

Usage recommendations

For correct operation, match the adapter to notebook models that explicitly list a 4.5 mm tip and 90W power requirement or reference MPN 937520-002. Use a properly rated mains supply, avoid prolonged use in poorly ventilated spaces, and inspect the cable and connector for damage before use. If the notebook specifies a different wattage or connector, choose the appropriate adapter to avoid underpowering or incompatible connections.
