Our take on the HP 65W 4.5mm Smart Adapter

This is HP's 65W AC adapter with the 4.5mm barrel tip, the standard charger for many HP Pavilion, Envy and ProBook laptops. It delivers 18.5V at up to 5A with fast charging and overvoltage protection, and includes a 70.9-inch cable with a right-angle plug plus a power cord. At $12.89 at eBay as of November 4, 2026, it sits near the bottom of its recent range; most new units sell for more.

Questions and answers

Will this fit my HP laptop?
It fits HP laptops with a 4.5mm round charging port, common on Pavilion, Envy and ProBook models from roughly 2015 onward. Check your port or original adapter label before buying; 7.4mm and USB-C models need a different charger.

The adapter, a 70.9-inch cable with a right-angle 4.5mm connector, a power cord and a warranty card. No USB ports or extra tips are included.
