Three-Pack USB-C Coupler Set

This three-pack provides three female-to-female USB-C couplers designed to join two USB-C cables into a single longer connection. They suit anyone who needs extra reach for charging, data or video cables at a desk, in a bag or on the move.

Aluminium Housing and Gold-Plated Contacts

Each coupler uses an aluminium alloy shell with gold-plated contacts to resist corrosion and wear. The construction keeps the connection secure and supports up to 240W charging, 40Gbps data transfer and 8K video at 60Hz when the linked cables and host devices also meet those specifications.

Plug-and-Play Installation

No drivers or software are required; simply insert a USB-C cable into each end. The only common issue is attempting to exceed the rated power, data or video limits of the shortest cable in the chain, which will cap performance to that cable's capability.

Questions about this item

How long will the gold-plated contacts on these USB-C couplers last before they need replacing?

The gold-plated contacts resist corrosion and daily wear, and the aluminum alloy housing maintains a secure fit, so the couplers are built to sustain consistent performance over time without a scheduled replacement interval.

What limits the 40Gbps data rate or 240W charging when the adapters are used continuously?

The couplers are rated for up to 40Gbps data transfer and 240W power delivery, so the practical limit under sustained use will be the capability of the connected cables and host devices rather than the adapters themselves.

Do these adapters generate noticeable heat or noise when passing 240W charging all day?

The aluminum alloy shell is heat-resistant and the couplers have no moving parts or active cooling, so they operate silently and dissipate warmth passively during continuous high-power charging.
