USB-C to 4.0 x 1.7mm Power Cable

This cable connects a USB-C power source to a laptop that uses a 4.0 x 1.7mm barrel jack. It is intended for users who need to charge a compatible notebook via a USB-C charger or power bank. The cable carries power only and does not support any data transmission. Its 1.5 metre length provides flexible placement on a desk or while travelling.

4.0 x 1.7mm Barrel Connector Compatibility

The single specification that determines fit is the 4.0 x 1.7mm barrel plug, which must match the laptop's DC input exactly. The cable is designed for notebooks that specify this connector size on their original adapter. No other barrel dimensions or USB-C power profiles are referenced in the product data.

Passive Cable Thermals and Power Delivery

As a passive wired assembly with a 4mm diameter cable, it generates no active heat or noise during operation. Power delivery is limited by the USB-C source and the laptop's own charging circuitry, not by the cable itself. The plug-and-play design requires no drivers or configuration for charging to begin.

Questions about this item

What does the 1.5 m cable length mean once I plug it into my laptop?

It gives you roughly 1.5 metres of reach between the USB-C charger and the 4.0 x 1.7 mm power jack on the notebook.

Which interface standard does the USB-C end follow, and what does that limit in practice?

The USB-C connector carries power only; there is no data lane, so it cannot be used for video, file transfer or peripheral signalling.

What physical clearance does the 4.0 x 1.7 mm barrel plug need to seat properly?

The straight 4.0 mm outer by 1.7 mm inner barrel requires a matching round jack with at least 4 mm hole depth and no surrounding lip that blocks the 4 mm cable body.
