Ultra-Short Keychain Cable

The FIELUX USB 4.0 cable measures five inches and combines a USB-C to USB-C connector with a built-in keychain loop. It targets users who need maximum portability for charging and data on the move. The compact form factor eliminates cable clutter in bags or pockets.

Suits Minimal Carry Needs

Professionals carrying a single high-power laptop and phone benefit from 240W charging and 40Gbps transfer in a tiny package. Buyers who need more storage length for desk setups or longer reach between devices should look at standard cables instead.

Plug-and-Play Simplicity

No drivers or software are required; the cable works immediately with any USB-C port supporting the relevant standards. The very short length can strain ports if devices sit far apart, so verify spacing before relying on it for video output.

Questions about this item

Do I need a USB-C charger rated for 240W to get the full charging speed?

Yes — the cable is built to PD 3.2, 3.1 and 2.0 standards and can carry up to 240W, so the charger and the device must both support that power level.

Will this 5-inch cable work with a Thunderbolt dock or hub I already own?

The cable is compatible with Thunderbolt devices and supports 40Gbps data plus 8K@60Hz video, so it will function with your existing Thunderbolt dock or hub.

How can I confirm the cable is delivering 40Gbps data after I plug it in?

Run a large file transfer between two USB 4.0 devices and check the sustained throughput in your OS; it should approach 40Gbps when both ends support USB 4.0.
