Which HP models will this S SKSTYLE charger work with?

This adapter is intended for HP laptops that accept the Smart Blue Tip (4.5×3.0mm) connector instead of USB-C. It supports a wide range of HP series including Pavilion x360, Envy, EliteBook, ProBook, Stream, Spectre x360, Chromebook 11/14, and many ZBook models.

• Pavilion x360 (11/13/15), Envy (13/15), Spectre x360

• Chromebook 11/14, Stream 11/14, selected ZBook notebooks
• Not compatible with USB-C charging ports—check your laptop’s charging jack first

How does the output and compatibility work for different laptop power needs?

The adapter’s rated output is designed to supply 19.5V at up to 3.33A (65W max) while remaining backwards compatible to 19.5V 2.31A (45W) operation where appropriate. When paired with a device that needs less power, the adapter will safely provide the lower current the laptop requests; it is not intended to convert USB-C power profiles.

• Output specification: 19.5V, up to 3.33A (65W) with backward compatibility to 2.31A (45W)
• Input range: 100–240V AC, 50–60Hz for global use
• Use only with devices that accept the HP Smart Blue Tip connector
• Not a USB-C PD adapter—requires matching physical jack

Who is this for: This S SKSTYLE 45W charger is intended for HP laptop and Chromebook owners who need a reliable replacement or travel adapter for devices that accept the HP Smart Blue Tip connector.
