What the cable is and who it suits

This two-pack of 3.3 ft USB-C to USB-C cables delivers up to 100 W of power with a built-in LED display that shows real-time wattage. An integrated E-Marker chip negotiates the optimal rate for each device, making the set useful for laptop, tablet, phone and console owners who want visible charging feedback.

Thermals, noise and power in normal use

The cable operates silently and remains cool during 100 W transfers thanks to the smart chip regulating current at 20 V and 5 A. No fans or moving parts are present, so there is no audible noise and no measurable heat buildup under typical charging loads.

What the bundled items and software change

Each pack includes two identical cables, doubling the number of devices you can monitor simultaneously without buying extras. The on-cable display replaces the need for a separate power meter, while the E-Marker logic automatically selects 18 W, 30 W, 45 W, 60 W, 65 W or 100 W profiles to match the connected hardware.

Questions about this item

How do I connect the LUOM YDSX cable so the LED display shows power correctly?

Plug the USB-C end marked for the charger into a PD-capable wall adapter first, then connect the other end to your device; the built-in E-Marker chip negotiates 5 A at 20 V and the display lights up automatically.

What part of the LUOM YDSX cable wears out first with daily bending?

The premium nylon braid protects the internal conductors, but repeated sharp bends near the connector strain relief can fatigue the E-Marker chip leads over time.

At what sustained power does the LUOM YDSX cable hit its thermal limit?

Continuous 100 W (20 V / 5 A) operation is the rated ceiling; beyond that the E-Marker will throttle current to protect the cable and connected device.
