What the cable does and who needs it

This SMUGDESK USB C extension cable adds 6.6 ft of reach to any USB-C device while preserving full 10 Gbps data and 100 W charging. It suits anyone who must place a laptop, tablet or phone farther from the host port without losing speed or power.

Behaviour under sustained load

The cord maintains 10 Gbps throughput and 20 V at 5 A continuously across its 6.6 ft length. Signal integrity and power delivery remain stable during long file transfers or extended charging sessions without the drops seen on shorter passive cables.

Thermals noise and power draw

Passive copper construction produces no fan noise and adds negligible resistance, so the cable stays cool to the touch even at 100 W. It draws only the power required by the connected device, imposing no extra load on the host port.

Questions about this item

Does the cable get warm when it delivers 100 W continuously?

The cable is rated for up to 100 W at 20 V and 5 A; normal operation at that level may produce some warmth but it is designed for sustained power delivery.

What must my device and charger support for 100 W charging to work?

Both the host and the power source need USB Power Delivery capable of 20 V at 5 A over a USB-C connection.

Will this cable work with an older USB 3.0 port that only does 5 Gbps?

Yes, the USB 3.1 Gen 2 cable is backward compatible and will run at the 5 Gbps limit of the older port.
