Lenovo Thunderbolt 4 Cable 1m

This one-metre cable connects Thunderbolt 4 hosts and peripherals with a USB-C to USB-C layout. It suits professionals who need a certified replacement link for docks, monitors or external storage.

40 Gbps bandwidth and 240 W charging

The link moves data at 40 Gbps while delivering up to 240 W (48 V at 5 A) to power hungry laptops. Thunderbolt 4 signalling keeps thermals low and the short length prevents signal loss in normal desk setups.

8K 60 Hz video requires DSC support

Display output reaches 8K at 60 Hz only when both source and sink implement DSC compression. Buyers whose devices lack DSC cannot achieve that resolution over this cable.

Questions about this item

How do I connect the 1 m Thunderbolt 4 cable to my dock and laptop?

Plug the USB-C connectors firmly into both ports until they click; the 1 m length keeps the dock close enough to avoid strain on the ports.

Will the 240 W charging capability degrade over time?

The cable is rated for 48 V at 5 A continuously; inspect the connectors periodically for debris or bent pins that could reduce contact quality.

What limits 8 K 60 Hz output during extended sessions?

Sustained 40 Gbps throughput can generate heat in the cable; ensure adequate airflow around the 1 m run to maintain signal integrity.
