Vszerda USB 3.1 Type-C to DC 4.5x3.0mm PD Adapter 90° HP

HP DC 4.5×3.0 mm charging adapter

This Vszerda adapter converts a USB Type-C charger into a 90-degree DC 4.5×3.0 mm plug for HP laptops. A built-in PD trigger requests 18 V to 20 V from a 65 W or 87 W USB-C power source. The copper construction carries the negotiated voltage to the laptop’s barrel jack. It does not support 5 V output.

Check your charger and laptop port

Verify that your HP model accepts a 4.5 mm outer diameter and 3.0 mm inner diameter barrel connector. Confirm the USB-C charger can deliver at least 65 W or 87 W and supports Power Delivery at 18 V or 20 V. The adapter only works when the charger’s rated power exceeds the laptop’s requirement. A lower-wattage or 5 V-only charger will not function.

Replaces a proprietary HP barrel charger

This cable lets you use a compact USB-C PD brick instead of the original HP barrel power supply. The 90-degree angled DC plug reduces strain on the laptop port in tight spaces. The upgrade is worthwhile when you want a single high-wattage USB-C charger for travel or desk use. It is not suitable for laptops that need a different barrel size or voltages outside the 18 V to 20 V range.
