SMUGDESK USB 4.0 Cable 3.3FT 240W 40Gbps Thunderbolt 3/4 8K@60Hz

USB4 cable for Thunderbolt 3 and 4 devices

This USB4 Gen 3x2 cable connects USB‑C laptops, tablets and phones to Thunderbolt 3 or 4 docks, monitors and storage. It delivers up to 40 Gbps data throughput and 8K at 60 Hz video, while supporting Power Delivery 3.1 Extended Power Range up to 240 W. The reversible USB‑C to USB‑C design works with existing USB 2.0, 3.0, 3.1 and 3.2 gear.

240 W charging headroom and 40 Gbps ceiling

The cable carries 48 V at 5 A for 240 W EPR charging, compatible with 140 W, 180 W and lower PD profiles such as 100 W and 60 W. A MacBook Pro 16 inch can reach 60 percent charge in 30 minutes when paired with a 140 W EPR charger. Data speed tops out at 40 Gbps with USB4 Gen 3x2 hosts; older USB 3.2 or Thunderbolt 3 links will run at their native lower rates.

One‑metre length limits desk reach

At 3.3 ft the cable suits close‑range connections such as a laptop to a dock or monitor on the same surface. It cannot span longer distances across a room or between floor‑standing equipment. Buyers needing more reach should select a longer active or optical USB4 cable instead.
