240W USB C Coupler (2 Pack), USB Type C Female to Female Adapter Extender Compatible with Thunderbolt 4/3 Support up to 240W Charging, 40Gbps Data Transfer and 8K@60Hz Video

As the title says. It was a partial success since one failed shortly after the return period ended. At least the other one works as advertised.

Je l’utilisé dans ma voiture (qui n’a pas de connection usb ) avec un autre accessoires pour brancher une clef usb dans la prise auxiliaire via un cordon usb vers cordon avec prise Jack afin que le son passe dans les hauts parleurs de ma voiture

Works on everything I tested these on. Just remember, if the little blue light doesn't come on unplug and flip one of the chords, the orientation of both cables needs to match, the couplers won't do that unfortunately but the light makes it easy.

I bought these specifically for use at work where I could plug in my charger and at the other side of the conference room still be able to charge my phone / laptop using the 2 x 2m USB c cables I already had in my bag. These are rated even higher than the 65W I need to charge my laptop and work perfectly

Power and data are flowing nicely. Can't give a comment on the data rate, since I'm not using powerful enough devices to check. Little led on both sides give a clear indication of power passing through. Seems it doesn't get hot, but again, I'm not using it at full capacity. Fit and finish is very nice looking, the cables are firmly attached and the metallic body is strong.

Works well as expected
