SKU CH-J39W-CRCD1

A 3.3 ft USB-C to USB-C cable with an LED power display, 100 W Power Delivery and 480 Mbps USB 2.0 data transfer

  • Real-time power readout with built-in LED display
  • 100W Power Delivery via E-Marker smart chip
  • 58% faster charging than 60W cables
  • 30,000+ bend cycles with nylon braid
  • 480Mbps data transfer at USB 2.0 speeds

What this cable delivers

This USB-C to USB-C cable carries up to 100 W of Power Delivery through a built-in E-Marker chip that negotiates the exact voltage and current each device needs. An integrated LED display shows the real-time wattage so you can confirm the charging rate at a glance. Data transfers at 480 Mbps over USB 2.0.

Who it suits and who it does not

The 3.3 ft length works well for desk or bedside charging where the power source is close to the device. Buyers who need more reach between outlets and hardware should look at a longer cable. The USB 2.0 data rate also means it is not intended for high-speed video or bulk file transfers.

Behaviour under sustained load

The alloy-shell connectors and nylon-braided jacket are rated for more than 30,000 bend cycles, and laser-welded joints resist separation during repeated plugging and unplugging. The E-Marker chip maintains stable power negotiation throughout long charging sessions, keeping output consistent from start to finish.

Questions about this item

Does this cable need a specific USB-C power adapter to deliver its 100W maximum?

It works with any USB-C adapter that supports 5–100W Power Delivery; the built-in E-Marker chip negotiates the correct voltage and current automatically.

Will the LED wattage display function when I connect this cable to a Thunderbolt 3 port on an older laptop?

Yes, the display shows real-time charging power whenever the cable is carrying a PD-negotiated charge, regardless of the host port generation.

How can I confirm the cable is actually providing fast charging after I plug it in?

The integrated LED display instantly shows the negotiated wattage, so you can verify the 100W (20V/5A) rate is active while charging.
