USB-C to 4.5x3.0mm power adapter

This cable converts a USB-C source to a 4.5x3.0mm barrel connector for charging compatible notebooks. It is intended for users who need to power a laptop with that specific barrel size from a USB-C charger or power bank. The adapter supports charging only and does not transmit data.

4mm wire diameter and 1.5m length

The cable uses a 4mm diameter wire and measures about 1.5 metres long. It is designed for plug-and-play operation with no driver installation required. Power draw and thermal behaviour follow the connected USB-C source and the notebook's own charging circuitry.

Compact build for portability

The small form factor makes it easy to carry and store in a laptop bag. The USB-C plug and 4.5x3.0mm barrel connector are moulded for a secure fit during daily use. Plug-and-play simplicity means it works immediately when connected to a supported power source and notebook.

Questions about this item

How do I connect the 4.5 x 3.0mm plug to my laptop and the USB-C end to the charger without reversing them?

Align the 4.5 x 3.0mm barrel connector with the laptop's power port and push straight in; insert the USB-C plug into the charger until it clicks, noting the cable only carries power.

Will the 4mm diameter cable or the 1.5m length require any periodic inspection or replacement?

Inspect the 4mm cable jacket and both connectors for fraying or bent pins after frequent bending; replace the adapter if the barrel tip becomes loose or charging becomes intermittent.

At what point does the 1.5m cable length or 4mm wire gauge limit sustained charging performance?

The 1.5m length and 4mm wire diameter set a practical limit on current delivery; sustained high-wattage charging may cause voltage drop or connector heating before the cable itself fails.
