HP laptop charging adapter

This Fervit adapter converts a USB-C power source into a 4.5 by 3.0 millimetre DC barrel plug for compatible HP laptops. A built-in PD trigger negotiates 18 to 20 volt output from a 65W or 87W charger. The 90-degree angled connector reduces strain on the laptop port. It does not support 5 volt operation.

Sustained power delivery

The adapter passes negotiated 18 to 20 volt DC power continuously while the attached charger maintains the PD contract. No active cooling is present, so the plastic housing relies on passive dissipation during prolonged loads. Performance stays stable as long as the source charger meets its own thermal limits. Voltage drops only if the charger reduces output.

Installation and common issues

Plug the USB-C male end into the charger and the DC male tip into the laptop; the 90-degree angle eases routing in tight spaces. The most frequent issue is a charger that cannot supply 65W or 87W at 18 to 20 volts, causing the trigger to fail. Using a lower-wattage or 5V-only source will not work. Ensure the barrel diameter matches the laptop exactly.

Questions about this item

How much heat or noise does the Fervit USB-C to DC 4.5*3.0mm HP Adapter produce when running all day?

The adapter has no fan or moving parts, so it runs silently and generates only minimal warmth during continuous use.

What must I already own for this adapter to power my HP laptop?

You need a USB-C charger that supports 65W or 87W Power Delivery at 18-20V output.

Will the 90° angled DC plug fit alongside the ports on my older HP laptop?

The right-angle design keeps the cable close to the chassis, reducing strain on the 4.5*3.0mm barrel jack and neighbouring ports.
