Thunderbolt 4 extension cable 0.8 m

This 0.8 m Thunderbolt 4 extension cable carries 40 Gbps data, 100 W power delivery and 8K video at 60 Hz. It uses a male-to-female Thunderbolt connector pair with triple shielding and an integrated E-marker chip. The cable is backward compatible with Thunderbolt 3 and USB 3.2, 3.1, 3.0 and 2.0 devices. It suits users who need extra reach for a dock or peripheral without losing full Thunderbolt 4 performance.

Check port gender and total length before ordering

Your device must provide a Thunderbolt or USB-C port that accepts a male plug, while the peripheral or dock needs a female receptacle. The supplier recommends keeping the combined cable run under 1.2 m for peak 40 Gbps throughput and under 1.5 m for reliable operation. Verify that your charger and host both support 20 V 5 A to reach the 100 W rating; actual charging speed depends on the connected hardware.

Nickel-plated connectors rated for 10 000 mating

The nickel-plated ends are designed to withstand up to 10 000 insertions, reducing wear on the host port when the cable stays plugged in. Aluminium-alloy housing uses integrated moulding without glue, while silver-clad and tinned copper conductors combine with multi-layer shielding for signal integrity. These construction choices aim to maintain high-speed data and power delivery over repeated daily use.

Questions about this item

What comes in the box and do I need to buy anything else to use it?

The package contains the Thunderbolt 4 extension cable with male-to-female connectors. You only need a Thunderbolt 3 or 4 host, cable or dock and a compatible device; no extra accessories are required.

Which length should I choose for the best 40 Gbps performance?

The cable is 0.8 m long. For full 40 Gbps speed the total link including your existing cable should stay under 1.2 m, and under 1.5 m for reliable operation.

What does the 100 W rating mean when I plug this into my laptop?

The cable carries up to 100 W (20 V 5 A) via its E-marker chip, so it can charge a laptop at full speed provided the charger and laptop both support that power level.
