4.0x1.7mm DC Jack to USB-C Adapter

This Fervit adapter converts a 4.0x1.7mm barrel jack input into a USB-C power output. It accepts 18-20V DC and delivers up to 65W through multiple voltage profiles including 5V/2A, 9V/3A, 15V/2A and 20V/3.25A. The 90-degree angled plug fits tight spaces around ports. It supports PD, QC2.0, QC3.0 and other fast-charge protocols for laptops, tablets and phones.

Replaces proprietary barrel chargers

Users with a 18-20V barrel power supply can switch to a single USB-C cable for charging. The upgrade is worth it when the original charger is lost, damaged or inconvenient to carry. It removes the need for a dedicated laptop brick if a compatible USB-C source is available. The adapter does not create power; it only passes what the barrel supply provides.

65W maximum output headroom

The adapter comfortably handles ultrabooks, tablets and phones that charge at or below 65W via USB-C PD. It runs out at devices requiring more than 20V or 3.25A, such as high-performance gaming laptops or workstations. Buyers must verify their device voltage and current match the supported profiles. It is not for hardware needing proprietary barrel negotiation or higher wattage.

Questions about this item

What size DC jack does the 4.0×1.7 mm input on this adapter fit?

The adapter accepts a 4.0 mm outer-diameter, 1.7 mm inner-diameter barrel plug, the common size used on many 18 V–20 V laptop chargers.

How do I connect the 90° angled USB-C plug without stressing the port?

Align the USB-C connector with the device port, then press straight in; the right-angle body lets the cable run parallel to the chassis so the plug does not lever against the socket.

When should I replace this 65 W adapter?

Replace it if the USB-C pins become loose, the barrel input wobbles, or the adapter no longer delivers the rated 5 V/2 A, 9 V/3 A, 15 V/2 A or 20 V/3.25 A profiles.
