Compact USB-C Power Adapter for 4.0 x 1.7mm Devices
This adapter cable connects a USB-C power source to equipment that requires a 4.0 x 1.7mm barrel jack. It suits users who need to power legacy laptops, routers or monitors from a modern USB-C charger or power bank. The short 15.5cm length keeps the link tidy on a desk or in a bag.
Direct Barrel Connection Without Extra Dongles
The cable terminates in a 4.0 x 1.7mm plug so no separate gender changer or extension is required. This single-cable approach reduces the number of joints that can loosen over time and eliminates the need to carry an additional adapter block when travelling.
Lightweight 11g Build with 15.5cm Reach
Weighing about 11g, the assembly adds negligible mass to a carry kit and puts minimal strain on the USB-C port. The 15.5cm span is long enough to bridge a charger on a floor strip to a device on a desk without pulling tight, yet short enough to avoid cable clutter in a compact workspace.

Questions about this item
Will the 4.0 x 1.7 mm connector or the USB-C plug need replacing after repeated insertion cycles?
The cable uses a standard USB-C plug and a 4.0 x 1.7 mm barrel connector; both are rated for typical daily mating cycles and require no scheduled replacement.
What stops the 15.5 cm cable from delivering full power during a long charging session?
The limit is the cable's conductor gauge and the 4.0 x 1.7 mm barrel interface, which together cap the safe current below what a bare USB-C PD negotiation might request.
Does the adapter get warm or draw extra power when left plugged in all day?
It is a passive 11 g cable with no active electronics, so it generates no measurable heat and consumes no power beyond the device's own draw.
