DC 6.0×1.4mm to USB-C PD adapter

This right-angle adapter converts a legacy DC 6.0×1.4mm barrel power supply into a USB-C Power Delivery source. It suits owners of older laptop bricks who want to charge modern USB-C laptops and smartphones without buying a new charger.

Repurposing a fixed-voltage DC brick for PD

The unit replaces a dedicated USB-C charger by adding an intelligent PD trigger chip that auto-negotiates 5V, 9V, 15V and 20V output stages. The upgrade is worth it when you have a spare 6.0×1.4mm adapter rated for sufficient wattage and need a compact, cable-free solution for daily or travel use.

Check barrel size and source adapter rating before

Verify that your existing power supply uses the exact 6.0×1.4mm centre-positive barrel and can deliver the current your target device requests. The adapter peaks at 140W and sustains 100W, so the source brick must meet or exceed the laptop’s PD power requirement.

Questions about this item

Does the 90-degree elbow on the 6.0×1.4mm barrel connector clear a tight laptop side port?

The right-angle Type-C male plug is designed to avoid cable bending stress and space crowding at the laptop side port, making it suitable for narrow desktop setups and docking stations.

What voltage steps does the built-in PD trigger chip negotiate with my USB-C laptop?

The intelligent PD trigger chip auto-negotiates 5V, 9V, 15V and 20V to match mainstream PD3.1 and QC fast-charge protocols for MacBook, Dell, Lenovo, HP and Android devices.

When should I replace the adapter if I use it daily with a 100W PD laptop?

Replace the unit if the flame-retardant shell shows heat discoloration, the 90-degree joint becomes loose, or the over-current, over-voltage and short-circuit protections activate repeatedly during charging.
