USB-C to DC 11.0x4.5mm Adapter

This Fervit adapter converts a USB-C Power Delivery source into a DC 11.0x4.5mm barrel jack for laptops. It includes an LED display that shows voltage, current and wattage in real time. The alloy shell protects the connectors and keeps the unit compact for travel. It suits users who want to power a barrel-jack laptop from a modern USB-C charger.

Sustained 100W Delivery

The adapter triggers a 20V 5A PD profile to deliver up to 100W continuously. It also supports 65W and an 18.5V to 20.5V range for lower-power devices. Full 100W output requires a charger and cable rated for at least 100W. The display lets you verify the actual power being drawn during extended use.

PD and QC Protocol Limits

Input relies on USB-C PD, QC 2.0 and QC 3.0 negotiation to reach the target voltage. The fixed DC male plug only fits devices with an 11.0x4.5mm jack, so laptops with other barrel sizes cannot connect. Buyers needing a different tip size or a higher voltage than 20.5V cannot use this adapter.

Questions about this item

Does the LED display stay bright or generate extra heat when the adapter runs at 100W all day?

The built-in LED display shows voltage, current and power in real time without active cooling; the alloy shell dissipates heat passively during continuous 20V 5A operation.

What USB-C charger and cable must I already own to reach the 100W rating?

You need a USB-C charger and cable rated for 100W or higher that support PD and QC 2.0 or 3.0 profiles to trigger the 20V 5A output.

Will this adapter work with my older 65W barrel-jack laptop that uses an 11.0x4.5mm tip?

Yes, the output also supports 65W and voltages between 18.5V and 20.5V, so it can power compatible legacy laptops with the same DC jack size.
