What to Compare Before Buying

- Power delivery: The cable supports up to 240W charging. Compare that with your charger and device requirements.
- Existing cable compatibility: The cable is meant to extend a USB-C or Thunderbolt cable. Confirm the cable you already use is suitable for this type of extension.
What Else You May Need
You will need a compatible USB-C or Thunderbolt cable to extend, plus a device and charger that match the setup you are building. If you are using it for a monitor, confirm that the rest of your connection chain supports the required video mode.
Before You Decide
Check the 0.5 m length, the male-to-female connector layout and the stated support for 40Gbps, 8K@60Hz, 4K@240Hz and 240W charging before choosing an offer. It is an extension cable, so it works as part of an existing USB-C or Thunderbolt setup rather than as a stand-alone lead.
