HP 90W Smart AC Adapter Indoor Black Laptop Power Supply 100-240V

The HP 90W Smart AC Adapter provides optimal power delivery for HP notebooks and helps compensate for power fluctuations. Designed for indoor use, this compact black power supply supports 100–240V input and includes a right-angled (90°) 4.5mm connector to reduce cable stress. An optional 4.5mm to 7.4mm conversion dongle is available for compatibility with older HP notebook models.

Advantages

Smart-pin technology controls power draw to supply only the energy the notebook requires, reducing the risk of power surges and improving efficiency. The right-angled 4.5mm connector allows easier connections in confined spaces and reduces cord bending to extend cable life. The included conversion dongle increases connection versatility by allowing use with legacy 7.4mm HP connectors.

Suitable for

• Replacing a lost or damaged HP notebook AC adapter
• Keeping as a backup adapter for travel or office use
• Charging HP notebooks that use the 4.5mm Smart pin connector

Verify the notebook is charging by checking the device’s charging indicator.

Recommendations

Use the adapter in dry, indoor environments and avoid placing the power brick on soft surfaces that block ventilation. Disconnect the adapter by pulling the plug, not the cable, to reduce strain. Keep the 4.5mm connector and optional dongle clean and free of debris for reliable contact.
