Fervit USB-C to DC 7.9x5.4mm Adapter

This new adapter converts a USB-C Power Delivery source into a 7.9x5.4mm barrel jack for laptop charging. It includes an LED display that shows voltage, current and power in real time. The unit supports up to 100W at 20V/5A and works with PD, QC2.0 and QC3.0 chargers.

Suits laptops with a matching 7.9x5.4mm DC input

Users whose laptops require a different barrel size or a voltage outside the 18.5V to 20.5V range cannot use this adapter. Buyers without a 100W-capable USB-C charger and cable will not reach the maximum output. The adapter is not for devices that charge only via proprietary connectors.

7.9x5.4mm barrel jack with 100W PD trigger

The single specification that decides fit is the 7.9x5.4mm output plug combined with the built-in 100W PD emulator trigger. Your laptop must accept this exact barrel size and operate within 18.5V to 20.5V. The charger and cable must also be rated for 100W to deliver full power.

Questions about this item

Does the DC 7.9x5.4mm barrel jack match my laptop's power port?

The adapter outputs through a DC male plug measuring 7.9 mm outer diameter by 5.4 mm inner diameter; verify your laptop uses this exact barrel size before purchasing.

What charger and cable are required to reach the 100W rating?

Use a USB-C charger and cable each rated for at least 100W; the built-in PD trigger negotiates 20V at 5A only when both meet that specification.

Will the LED wattage display eventually dim or fail?

The integrated LED screen shows voltage, current and power in real time and has no user-replaceable parts; if it fails the entire adapter must be replaced.
