SMUGDESK 100W USB C to USB C Cable with LED Display (Black, 2-Pack, 3.3ft)

100 W USB-C charging cable with live power readout

This two-pack of 3.3 ft USB-C to USB-C cables delivers up to 100 W of power for laptops, tablets and phones. An integrated LED display shows the real-time charging rate so you can see exactly how much power is flowing. A built-in E-Marker chip negotiates the optimal rate — 18 W, 30 W, 45 W, 65 W or 100 W — for each connected device. The nylon braid adds durability for daily carry.

Capacity and headroom: what it handles

The cable supports 5 A at 20 V for full 100 W delivery, enough to take a 16-inch MacBook Pro from 0 to 40 % in 30 minutes or a Samsung S20 from 0 to 80 % in the same time. It will not exceed 100 W, so devices that require higher wattage will charge at the cable’s maximum instead. The 3.3 ft length suits desktop or bedside use but may be short for wall outlets across a room.

LED display and E-Marker chip: what the extras

The LED readout removes guesswork by showing the instant wattage, letting you confirm that fast charging is active. The E-Marker chip automatically selects the highest compatible profile — 18 W, 30 W, 45 W, 65 W or 100 W — protecting the battery from mismatched current. No software or drivers are needed; the intelligence is entirely inside the cable. Buyers who need longer runs or multiple simultaneous device connections will need additional cables.
