Two-pack extension for USB-C devices

This two-pack provides two male-to-female USB Type-C extension cables. Each cable extends an existing USB-C connection by 0.5 metres and supports 20 Gbps data rates, 240 W power delivery and 4K video at 60 Hz. They suit users who need extra reach for external SSDs, eGPU enclosures or monitors without replacing their existing host-to-device cable.

Thermals noise and power in normal use

The cables carry up to 50 V at 5 A for 240 W charging with PD 3.1 and QC 4.0, staying backward compatible with 100 W, 60 W and lower profiles. Gold-plated contacts and a nylon-braided jacket reduce resistance and heat during sustained high-power or high-speed transfers. No active cooling or fans are present, so operation remains silent.

Bundled accessories and software impact

The package contains only the two extension cables; no host-to-device USB-C male-to-male cable is included. Users must supply their own 20 Gbps-rated cable to achieve the full 20 Gbps speed and 4K video capability. No driver, firmware or configuration software is required or provided.

Questions about this item

How do I install the 0.5 m male-to-female USB-C extension without losing the 20 Gbps data rate?

Plug the male end into a USB 3.2 Gen 2, USB4 or Thunderbolt 3/4 port, then connect a certified USB 3.2 Gen 2 male-to-male cable (not included) to the female end; both links must be Gen 2 to keep the 20 Gbps speed.

What maintenance will the 24-pin gold-plated connectors and nylon braid need over time?

Inspect the gold-plated pins for dust or oxidation every few months and clean gently with a dry brush; the braided jacket resists abrasion but check for kinks near the strain-relief collars after heavy flexing.

What limit appears first when I push 240 W through the cable continuously?

The 50 V / 5 A PD 3.1 ceiling is reached first; sustained 240 W delivery requires a matching 240 W adapter and active cooling at both ends to avoid thermal throttling.
