Two-Pack USB-C Extenders for Tight Ports

This two-pack of Cellularline USB-C extender adapters adds 5 inches of reach to male-to-female connections. The low-profile design fits alongside phone cases and crowded ports without blocking adjacent sockets. Each adapter handles up to 240 W of power delivery and 40 Gbps data throughput. They suit users who need extra clearance for docks, chargers or peripherals.

Passive Length Adds Signal Risk Beyond Spec

At 5 inches the adapter stays within the passive-cable window for 40 Gbps operation, but any chained cables or longer runs will drop to lower USB speeds. The extender itself does not re-drive the signal, so total link length must respect the host controller limits. Thunderbolt certification covers the connector interface, not the combined cable assembly. Builders planning daisy-chained setups should test the full chain before relying on peak throughput.

Replaces Rigid Dongles That Stress Ports

The adapter replaces short right-angle dongles or stiff cable ends that lever against device ports. The flexible 5-inch tail reduces mechanical stress on laptop and phone sockets during daily plug cycles. It is not a substitute for active Thunderbolt cables when runs exceed passive limits, nor does it add ports — buyers who need hub functionality or longer reach should look elsewhere.

Questions about this item

Should I pick the 2-pack or buy a single extender?

The product is sold only as a 2-pack, so you receive two identical extenders in one purchase.

Will I actually see 40 Gbps transfer rates with this extender?

The adapter supports up to 40 Gbps, but real-world speed depends on the host port, cable quality and the connected device.

Does the USB-C interface limit the 240 W power rating in any way?

The extender passes up to 240 W through its USB-C male-to-female connection without reducing the power delivery specification.
