High-speed data and charging cable

The SMUGDESK USB C 4.0 cable delivers up to 40Gbps transfer speed and 240W power delivery for laptops, tablets, phones and external SSDs. It includes an E-Marker chip for Thunderbolt 3 and 4 compatibility. The five-foot length suits desktop and mobile workstations.

Thermals noise and power draw

The cable handles PD3.1 Extended Power Range at 48V/240W, 36V/180W and 28V/140W without active cooling. It charges a MacBook Pro 16 from zero to sixty percent in thirty minutes. No fan or radiator is present, so operation is silent.

Bundled accessories and software

No additional adapters, docks or software utilities are included in the package. The E-Marker enables automatic negotiation with Thunderbolt 3 and 4 hosts, hubs and NVMe enclosures. Buyers needing legacy USB-A or HDMI connectors must source them separately.

Questions about this item

How do I install the SMUGDESK USB C 4.0 cable so the E-Marker chip negotiates 240W PD 3.1 EPR?

Plug the cable firmly into both USB C ports until the connectors seat fully; the E-Marker then negotiates 48V 240W, 36V 180W or 28V 140W automatically — if the laptop still shows lower wattage, unplug both ends, wait five seconds, then reconnect to reset the handshake.

What maintenance or replacement will the SMUGDESK USB C 4.0 cable need later?

Inspect the USB C plugs periodically for debris or bent pins; wipe contacts with a dry lint-free cloth if charging slows or 40Gbps transfers drop — replace the cable if the housing cracks or the E-Marker fails to negotiate 240W after a clean re-seat.

What limit appears first on the SMUGDESK USB C 4.0 cable during sustained 240W charging?

The 5 Ft length and 48V 240W PD 3.1 EPR rating mean connector temperature rise is the first limit; if the plugs become uncomfortably hot, reduce load or improve airflow — the cable supports 240W continuously only while contacts stay within safe operating temperature.
