Ubluker UB405M USB-C Cable, 40Gbps, 240W, 0.5m Braided

For a USB-C setup that needs fast file transfers, display connectivity or high-power charging, the Ubluker UB405M brings those jobs together in one cable. Its 0.5m length suits a compact desk arrangement or a close connection between devices. Need to connect a compatible display and charge from the same cable? It supports USB4 and PD 3.1 for a versatile everyday link.

Tips for day-to-day use

At 0.5m, this cable is well suited to linking nearby kit, such as a laptop to a USB-C display or dock, or a phone to a charger on the same desk. It can also connect compatible external storage, tablets and other USB-C devices, keeping a short setup tidy. For the stated data and charging capabilities, the connected devices, charger and any dock or display must support the relevant USB-C standards too.

The braided nylon exterior and natural titanium gold colour give the cable a distinct finish, while its 24-pin USB-C design and built-in E-marker support its high-power and data functions. The short format is particularly handy where a longer cable would leave extra slack between devices.

Why it’s worth it

The UB405M is designed to do more than charge: it supports data transfer up to 40Gbps, video and audio connections, and charging up to 240W with PD 3.1. That makes it useful for a compatible laptop-and-display setup, transferring large files to external storage, or charging a suitable USB-C device without swapping between separate cables for each task. Thunderbolt 4/3 and a range of USB standards are also listed, making it a practical choice for mixed USB-C equipment when the connected devices support those modes.

Buyers speak positively about its speed, charging and connectors, and some report using it with external displays. Feedback on handling is more varied: the braided build appeals to some, while others find the cable thick or less flexible. That’s worth bearing in mind when planning a close, fixed connection rather than a route that needs frequent bending.
