Compact USB-C to DC 4.5x3.0mm adapter with 90-degree angled plug and LED display showing voltage, current and power

Fervit

Fervit USB-C to DC 4.5x3.0mm 100W PD adapter with LED display

SKU CH-TC0T-JXYEJ

Converts USB-C PD input to a 4.5×3.0 mm DC jack at up to 100 W with a 90-degree plug and live voltage, current and power readout

  • Delivers up to 100 W through a DC 4.5x3.0 mm jack
  • Real-time voltage, current and power readout on LED display
  • 90-degree angled connector fits tight port clearances
  • Works with PD, QC 2.0 and QC 3.0 chargers from 65 W upwards
  • Alloy shell protects the plug for durable daily use

Adapter purpose

The Fervit adapter converts a USB-C Power Delivery source into a 4.5x3.0mm DC barrel output for laptops that charge through that specific jack. It supports PD and QC2.0/QC3.0 input protocols and includes a built-in 100W trigger to request 20V at up to 5A from a compatible charger.

Suitability

This suits owners of laptops with a 4.5x3.0mm DC input who want to power them from a high-power USB-C charger and monitor the live voltage, current and wattage on the integrated LED display. The 90-degree angled plug helps where side clearance is tight. Buyers whose laptops use a different barrel size, a proprietary connector or require a fixed voltage other than 20V should look elsewhere.

Deciding specification

The adapter only passes through 20V DC at up to 5A, so the charger and cable must each be rated for 100W or higher to reach the maximum output; lower-rated sources will fall back to reduced power levels such as 65W.

Questions about this item

What USB-C standard does the adapter use and what power does it cap at?

It uses USB-C PD with QC2.0/QC3.0 and caps at 100W 20V/5A output.

What DC jack size and angle does the adapter need to fit?

It needs a 4.5x3.0mm DC jack and uses a 90-degree angled connector for tight spaces.

How is the adapter installed and what step is often missed?

Plug the USB-C male end into a 100W-rated charger and cable, then connect the DC male jack to the laptop; the 100W charger and cable requirement is often overlooked.
