Moving 8K footage off an external SSD, or running a one-cable desk setup? This Cable Leader USB4 Gen 3x2 cable carries 40Gbps of data transfer, up to 240W of charging power, and 8K video over a single USB-C connection. USB4 and USB 4 are the same standard, so either spelling works. The E-Marker chip identifies the cable to the host so USB Power Delivery 3.1 Extended Power Range can negotiate the full 48V/5A path that gaming laptops and mobile workstations need when a 100W cable stalls them. Video runs at 8K 60Hz, 4K 120Hz, or dual 4K 60Hz through DisplayPort Alt Mode, so one cable drives a docking station, a monitor, and charging at once. Inside, eight shielded 30 AWG coaxial lines carry the high-speed lanes under a 25-micron copper foil shield. Compatible with MacBook Pro, Dell XPS, ThinkPad, Surface, Galaxy, iPad Pro, Steam Deck, and USB-C docking stations, and backward compatible with USB 3.2, 3.1, 3.0 and 2.0 hosts. Best for: USB4 laptops, docks, NVMe SSD enclosures, and 4K or 8K monitors. Not for: USB-A host ports, or runs longer than 3.3ft (1m). RoHS compliant.

Replace the three cables behind your laptop with one. Plug into a USB4 docking station and get monitor, peripherals, and charging on a single run. Pull 8K or RAW footage off an NVMe SSD enclosure at 40Gbps instead of waiting on a 10Gbps cable. Charge a gaming laptop at up to 240W while an 8K display stays connected. Both ends are USB-C and reversible.
A USB-C cable without an E-Marker chip is limited to 3A, which caps charging at 60W no matter how strong the charger is. This cable carries an E-Marker that declares 5A and Extended Power Range to the host, so USB Power Delivery 3.1 can negotiate up to 48V/5A — 240W. The E-Marker requirement and the 48V/5A EPR path are both defined by the USB-IF in the USB Type-C and USB Power Delivery specifications.
Each of the eight high-speed conductors is an individually shielded 30 AWG silver-coated-copper coaxial line, the construction 40Gbps needs to hold signal over a full meter. A 25-micron copper foil wraps the whole bundle against interference. Connectors are double-molded, polyamide resin inside and TPE outside, in a PC and ABS shell. The 4.95mm PVC jacket is VW-1 flame-rated and coils flat into a bag.
Every unit is tested for opens, shorts, and miswires on the production line, and each run is sample-tested during production for continuity and data integrity. Manufactured to RoHS environmental standards (lead, mercury, and cadmium-free). If your cable arrives defective or stops working in normal use, Cable Leader handles replacement requests directly — no manufacturer redirects.
