100W USB-C 3.1 Cable 2-Pack

This two-pack supplies two three-foot USB-C to USB-C cables rated for 100 W power delivery and USB 3.1 Gen 2 data speeds. Each cable includes an E-Marker chip to negotiate the full 100 W charge safely. They suit anyone who needs reliable charging and fast file transfers between USB-C devices.

For charging laptops and moving large files

The cables deliver 10 Gbps bandwidth and support 4K 60 Hz video output, so they work well for docking a laptop to a monitor or shifting multi-gigabyte projects. Buyers whose devices only support USB 2.0 speeds or lower power profiles will not gain the rated performance. Those who require longer reach than three feet should consider a different length.

E-Marker chip enables 100 W delivery

The built-in E-Marker is the single specification that guarantees the cable can handle the full 100 W power negotiation. Without it, a USB-C cable may default to a lower wattage and charge larger laptops slowly or not at all.

Questions about this item

What does the 10Gbps rating mean when I plug the cable into my laptop and drive?

The 10Gbps rating is the maximum theoretical throughput of the USB 3.1 Gen 2 link; real-world file transfers will be lower and depend on the speed of the host controller, the storage device and any other traffic on the bus.

Which USB standard does the cable implement and what does that cap in practice?

The cable implements USB 3.1 Gen 2, which caps the data lane at 10Gbps, the video lane at 4K 60Hz DisplayPort Alt Mode and the power lane at 100W Power Delivery.

What physical clearance do I need for the connectors to fit side-by-side on a crowded port block?

Each connector is a standard USB-C plug; allow roughly 8–9 mm width per plug so two cables seated next to each other need about 18 mm of clear port spacing.
