USB-C Female to DC 4.0x1.7mm PD Cable

This cable converts a USB-C Power Delivery charger into a fixed 18V-20V DC supply for laptops that use a 4.0×1.7mm barrel connector with centre positive polarity. It integrates a built-in PD trigger emulator chip to negotiate the required voltage automatically. The design targets users who want to replace a bulky proprietary power brick with a lighter, universal charging solution for home, office or travel use.

Replaces proprietary laptop charger

It removes the need to carry the original laptop power adapter when a compatible USB-C PD charger supplying 20V output is already available. The jump is worthwhile only if the charger delivers sufficient wattage for the laptop's power demand and the notebook's DC port matches the 4.0×1.7mm specification. The cable supports charging only and provides no data transmission capability.

Sustained charging with safety protection

Premium oxygen-free copper wire reduces power loss during continuous operation. Multi-layer protection guards against overvoltage, overcurrent, short circuit and overheating to protect the laptop battery over extended sessions. A precisely moulded DC plug maintains a tight connection that resists intermittent power cuts caused by movement or vibration. The cable outputs 18V-20V exclusively and cannot support 5V low-voltage devices.
