Fervit USB-C to DC Adapter

The Fervit adapter converts a USB-C Power Delivery source into a 5.5×2.1mm barrel output for laptops. An integrated LED display shows voltage, current and power in real time. It supports up to 100W at 20V/5A for compatible devices.

Check your laptop and charger first

Verify that your laptop uses a 5.5mm outer diameter and 2.1mm inner diameter DC jack. The USB-C charger and cable must each be rated for 100W or higher to reach the maximum output. Lower-rated sources will deliver reduced power such as 65W.

Display and trigger built in

The on-board wattage display lets you confirm the active charging rate at a glance. A built-in 100W PD trigger negotiates the required voltage automatically. No extra software or drivers are needed for operation.

Questions about this item

Does the box include a USB-C charger and cable, or do I need to supply my own?

Only the adapter is included; a USB-C charger and cable rated for 100W must be provided separately.

My laptop needs 20 V at 5 A — will this adapter deliver that, or should I choose a different model?

The adapter outputs DC 20 V 5 A up to 100 W and also supports 65 W and voltages from 18.5 V to 20.5 V, so it matches a 20 V 5 A requirement.

What does the 100 W rating mean when I plug it into my laptop?

With a 100 W USB-C charger and cable the adapter can deliver up to 20 V at 5 A, and the built-in display shows real-time voltage, current and power.
