DC 4.0 x 1.7mm to USB-C Adapter

This adapter converts a 4.0 x 1.7mm barrel jack into a USB-C female port using a 15cm cable. It supports power delivery profiles up to 65W including 5V/3A, 9V/3A, 12V/3A, 15V/3A and 20V/2.25A. The ABS housing measures 70 x 30 x 17mm for a compact footprint. Plug-and-play operation requires no drivers or configuration.

Suits users adapting barrel chargers

Ideal for powering USB-C devices from existing 4.0 x 1.7mm barrel power supplies within the 65W limit. Not for users whose source connector uses a different barrel diameter or centre pin size. Not for setups needing more than 20V or 2.25A at the highest profile. Not for data transfer or video output requirements.

Single spec: 4.0 x 1.7mm barrel input

The 4.0 x 1.7mm barrel jack is the only physical input interface and it must match the charger exactly. Mismatched dimensions will prevent a secure connection and power delivery. Verify the charger tip measures 4.0mm outer diameter and 1.7mm inner diameter before purchase. This single dimension decides compatibility.

Questions about this item

What power profiles does the USB-C female port on this Vszerda adapter support?

The USB-C female port delivers 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A, reaching a maximum of 65W when the input is 20V or higher.

What are the overall dimensions of the adapter body that must clear surrounding ports?

The adapter body measures 70mm by 30mm by 17mm, so check that adjacent connectors leave enough space for this footprint.

How do you connect the 4.0x1.7mm barrel jack to the adapter without reversing polarity?

Insert the 4.0mm outer diameter and 1.7mm inner diameter barrel plug fully into the female jack; the keyed shape prevents reverse insertion, then plug your USB-C device into the female port.
