DC 4.5 x 3.0mm to USB-C Adapter

This adapter converts a 4.5 x 3.0 mm DC barrel jack into a USB-C female port, allowing laptops or devices with that barrel input to charge from a USB-C power source. It supports power delivery profiles of 5 V, 9 V, 12 V, 15 V and 20 V up to a total of 45 W. The compact ABS housing measures 70 x 30 x 17 mm.

Build integration and cable reach

The 15 cm cable bridges the gap between a USB-C charger and the device’s barrel socket without adding bulk. Plug-and-play operation requires no drivers or configuration. It frees users from carrying a dedicated barrel-tip charger when a multi-port USB-C supply is already available.

Sustained load behaviour

Rated for 45 W continuous output, the adapter delivers 20 V at 2.25 A when the source provides 20 V or higher. Lower voltage profiles maintain 3 A current. The short cable and solid connectors minimise voltage drop during extended charging sessions. Not suited for devices needing more than 45 W or a different barrel diameter.
