Black right-angle adapter with 4.0 by 1.7 mm barrel plug and USB-C socket

Fervit

Fervit DC Jack 4.0x1.7mm to USB-C 90° 65W Power Adapter

SKU CH-1G4Y-5J84Z

Converts a 4.0×1.7 mm DC barrel jack into a 90-degree USB-C plug delivering up to 65 W with PD and multiple fast-charge protocols

  • 65 W max output charges laptops and phones quickly
  • 90° angled plug fits tight spaces around the port
  • Accepts DC 18 V–20 V input from existing power bricks
  • Supports multiple fast-charge protocols including PD and QC
  • Converts 4.0×1.7 mm barrel jack to USB-C connector

Purpose & Audience

This Fervit adapter converts a 4.0x1.7mm DC barrel input into a USB-C output, delivering up to 65W through multiple fast-charge protocols. It suits owners of laptops, tablets or phones that charge via USB-C and need to run from an existing 18-20V barrel power supply.

Fit & Limits

The unit works when your source provides 18-20V DC and your device accepts USB-C Power Delivery or one of the listed proprietary standards. It will not help if your barrel tip is a different diameter, if your source voltage falls outside the 18-20V range, or if your device requires more than 65W.

Deciding Specification

The 90-degree angled USB-C plug is the critical feature; it lets the cable sit flush against the device even when surrounding space is tight, preventing bent connectors and strained ports in cramped docking setups.
