Product identity and target user
This Fervit adapter converts a USB-C Power Delivery source into a 5.5×2.5 mm DC barrel output for laptops. It is intended for users who want to power or charge a compatible DC-input notebook from a USB-C charger rated at up to 100 W.
Setup checks before ordering
Verify that your laptop uses a 5.5 mm outer diameter and 2.5 mm inner diameter DC jack and accepts 20 V input. Confirm your USB-C charger and cable are rated for 100 W or higher to reach the maximum 20 V 5 A output; lower-rated chargers will only deliver reduced power.
What the bundled features change
The built-in LED display shows real-time voltage, current and wattage so you can confirm the active power level at a glance. An internal 100 W PD trigger negotiates the 20 V 5 A profile automatically, while the alloy shell protects the connector during transport and daily use.

Questions about this item
What comes in the box and do I need to buy a USB-C charger or cable separately?
The adapter itself is included. You must supply a USB-C charger and cable rated at 100 W or higher to reach the 100 W output.
How do I know which USB-C charger capacity to choose for this 5.5×2.5 mm barrel adapter?
Pick a charger that delivers 20 V at 5 A (100 W) and supports PD 3.0; the adapter also works with 65 W sources at 18.5–20.5 V.
What does the 100 W rating mean when the adapter is connected to my laptop?
It means the adapter can pass up to 20 V / 5 A from a compliant 100 W USB-C charger to the DC jack, and the built-in display shows the real-time voltage, current and power being delivered.
