Thunderbolt 4 USB4 Cable 1.5 Ft 240W

The SMUGDESK Thunderbolt 4 USB4 Cable is a 1.5 Ft USB-C to USB-C connection built for professionals and creators who need maximum bandwidth and power delivery in a short run. It suits laptop users linking a dock or eGPU, and desktop builders routing a tidy connection between a host port and a nearby peripheral.

Build integration with 40Gbps bandwidth and 240W

The cable carries up to 40Gbps data throughput when paired with Gen3 ports, dropping to 20Gbps on Gen2 interfaces, so actual speed depends on the host and device capabilities. It delivers up to 240W (48V/5A) charging with a compatible power source, freeing the user from carrying a separate brick for phones, accessories or gaming laptops. A single cable handles both high‑speed data and heavy charging loads, reducing cable count on the desk.

Bundled capabilities for 8K 60Hz

The link supports a single 8K or 6K display at 60Hz, or dual 4K 60Hz monitors when two cables are used, enabling high‑resolution multi‑monitor setups without compression. Backward compatibility with Thunderbolt 3 and 4 hosts means existing docks, hubs and eGPU enclosures work immediately. No extra drivers or software are required; the cable is plug‑and‑play across supported USB‑C and Thunderbolt ports.

Questions about this item

How much power can the cable deliver when paired with a compatible charger?

The cable supports up to 240W (48V/5A) power delivery when used with a compatible charger, allowing it to charge virtually any USB-C device from phones to gaming laptops.

Does the cable generate noticeable heat or noise during sustained 240W charging or 40Gbps data transfers?

The cable is a passive copper assembly with no active components, so it produces no noise; any warmth under maximum load is normal for high-current conductors.

What host ports and chargers are required to reach the advertised 240W charging and 40Gbps speeds?

To achieve 240W charging you need a USB-C charger and device that support 48V/5A; for 40Gbps data both ends must be Thunderbolt 4 or USB4 Gen3 ports — USB 3.2 Gen2 ports limit bandwidth to 20Gbps.
