Slim USB-C cable with straight connectors, matte finish, 4.9FT length

Fervit

Fervit USB4 cable 20Gbps 240W 8K@60Hz 4.9FT

SKU CH-B8CH-XMKXW

A flexible USB-C cable delivering 20Gbps data transfer, 240W charging and 8K@60Hz video output over 4.9FT

  • 20Gbps bandwidth moves large files in seconds
  • 240W PD 3.1 charging powers laptops and phones
  • 8K@60Hz video extends to dual 4K displays
  • E-marker chip regulates voltage for safe charging
  • 9FT slim cable fits tight workspaces

Fervit USB4 cable 20Gbps 240W

The Fervit USB4 cable delivers up to 20Gbps data transfer for Thunderbolt 3, 4 and 5 devices. It also supports 10Gbps and 5Gbps connections. An integrated E-marker chip enables 240W charging under PD 3.1 while remaining compatible with 140W, 100W and 60W power profiles. Video output reaches 8K at 60Hz or dual 4K at 60Hz when the host port supports DP Alt Mode.

E-marker chip and PD 3.1

The built-in E-marker chip negotiates power up to 48V5A and protects devices by controlling current and voltage changes. Backward compatibility with PD 3.0 and 2.0 means the same cable charges phones, tablets and laptops without extra adapters. Dual-monitor setups require two cables, so a single cable drives one external display at the stated resolutions.

Flexible slim 4.9FT design

A 4.9FT length suits desk and travel use while the slim, flexible jacket resists tangling. USB-C connectors on both ends fit Thunderbolt 3, 4 and 5 ports as well as standard USB-C devices. The cable carries data, power and video simultaneously, reducing the number of separate cords needed for a typical workstation.

Questions about this item

Will the E-marker chip or connectors wear out and need replacement later?

The cable uses a built-in E-marker chip for PD 3.1 negotiation up to 48V5A; passive copper construction means no active components to replace, only the connectors if physical damage occurs.

What limits sustained 20Gbps throughput during long transfers?

The 4.9FT length meets USB4 20Gbps signal-integrity requirements; thermal throttling in the host or device controller is the first practical limit, not the cable itself.

Does the cable get hot or draw extra power when running 240W charging all day?

The E-marker chip manages PD 3.1 current and voltage negotiation up to 48V5A; the cable carries the negotiated power without active conversion, so heat rise stays within normal copper-conductor limits.
