Two short black USB-C cables coiled together

Aomoproing

Aomoproing USB C 3.2 Gen2 20Gbps 240W PD3.1 cable 0.5m 2-pack

SKU CH-03W3-R1MMZ

Two USB-C cables deliver 240W PD 3.1 charging, 20Gbps data and 4K@60Hz video in 0.5m lengths

Cable Length 0.5m

  • Charges at up to 240W with PD 3.1 and E-Marker chip
  • Transfers data at 20Gbps on USB 3.2 Gen 2 devices
  • Drives 4K@60Hz video to compatible displays
  • Backward compatible with PD 3.0 and QC 3.0 adapters
  • Two 0.5m cables included for desk and travel use

Two-pack USB-C 20 Gbps cable

This two-pack provides two USB-C to USB-C cables rated for USB 3.2 Gen 2 speeds of up to 20 Gbps. Each cable measures 0.5 m and carries an E-Marker chip for Power Delivery 3.1 negotiation up to 240 W. They suit users who need short, high-current links for charging and data between compatible laptops, phones and peripherals.

Thermals noise and power draw

Passive construction means no fans or active cooling, so the cables add no audible noise to a setup. The E-Marker chip manages PD 3.1 handshakes up to 50 V at 5 A, allowing connected chargers to deliver 240 W, 100 W, 96 W, 87 W, 61 W, 60 W, 30 W, 18 W or 15 W as negotiated. Backward compatibility covers PD 3.0, PD 2.0, QC 4.0, QC 3.0 and QC 2.0 profiles.

Sustained load behaviour

Under continuous 240 W charging the conductors and E-Marker maintain negotiated voltage and current without thermal shutdown, provided the host charger and device support the same PD 3.1 level. Data throughput holds at 20 Gbps only when both ends connect to USB 3.2 Gen 2 ports; otherwise the link falls back to USB 3.1, 3.0 or 2.0 speeds. Video output remains stable at 4K 60 Hz for the duration of the session.

Questions about this item

How do I plug in the 0.5 m Aomoproing cable so the E-Marker chip negotiates 240 W PD 3.1 charging?

Connect each USB-C end firmly into a USB 3.2 Gen 2 port on both the charger and the device; the E-Marker chip then communicates 50 V / 5 A capability automatically.

When will the E-Marker chip or connectors need replacement on this 240 W cable?

The E-Marker chip is built into the plug and rated for the cable's lifetime; only physical damage to the USB-C connectors would require a new cable.

What stops the 20 Gbps data rate during a long file transfer?

Sustained 20 Gbps needs both host and peripheral to stay in USB 3.2 Gen 2 mode; thermal throttling or a port falling back to USB 3.1 cuts the speed first.
