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

This adapter converts a USB-C PD source into a 7.9x5.4mm DC barrel output for laptops. It delivers up to 100W at 20V 5A and includes an LED display showing real-time voltage, current and power. The 90-degree plug fits tight port clearances.

Plug-and-play setup with charger limits

The unit is fully plug and play with no drivers required. An alloy shell protects the connectors during frequent use. To reach 100W output, both the USB-C charger and cable must be rated for 100W or higher; lower-rated sources will only provide reduced power such as 65W.

Check laptop jack and PD source before ordering

Verify that your laptop uses a 7.9x5.4mm DC input jack and accepts 20V within the 18.5V to 20.5V range. Ensure your USB-C power supply supports PD 2.0 or 3.0 at 100W. This adapter is not for devices needing a different barrel size or voltage.

Questions about this item

How do I confirm the adapter is delivering the correct power after plugging it in?

The built‑in LED display shows real‑time voltage, current and power so you can verify the output matches the expected 20V 5A 100W level.

What comes in the box and what must I supply separately?

The package contains the USB‑C to DC 7.9x5.4mm 90° adapter only; you must provide a USB‑C charger and cable rated at 100W or higher to achieve full output.

Which charger specification should I choose to reach the 100W maximum?

Select a USB‑C charger and cable that support 100W Power Delivery; lower‑rated sources such as 65W will limit the adapter to that lower output.
