Duttek USB C Coupler 40Gbps, USB C Female to Female Adapter supports 8k@60HZ and 100W fast charging Compatible with Thunderbolt 3/4,USB Type C interface devices

Ordered one night and delivered next day. The coupler has worked perfectly and got me started when I found my new ear bud charger had a male plug which didn't like the male on my charging lead. The tiny Duttek coupler got them working together. Many thanks.

Tried for the first time today, works perfectly

Very good but the adapter is handed as highlighted by another reviewer. This should be made plan by the seller. I am sure other returns would be prevented if it was clear in the sales details

I purchased this as part of a setup to get display port output to my Viture Luma display glasses. Initially the item didn't work. I'd read that orientation matters, so I swapped that and it worked fine; e.g. if the printed surface is showing, unplug, rotate so the printed face is facing away then reconnect. In persevering I also swapped which end went to the PC and which to the glasses, which might have made a difference too even though it shouldn't. So if not working, methodically try different connection orientations (there are eight possible permutations) and at least one is likely to work.

Be careful when connecting, while connection orientation matters not for charging, for data it does matter. No where do they tell you this so you have a 50/50 chance of connecting the incorrect way around. I have marked the cables I use with the adapter, as this kinda works. More expensive couplers have the additional data connections, that this device lacks. Since I can buy a braded 1.5m PD USB cable rated up to 60w for £5, I cannot give this item any more than 3 starts, for decent build quality. Its not easy to use because of this and many may think it incompatible with their equipment. It seems well built from decent quality materials, but skimping on the data reversal circuitry is not excusable.

I bought this to connect to my JSAUX dock via a 100w Anker cable, as the dock USB c isn't long enough to connect the Ally then play on the couch whilst hooked up to the dock (if you're wondering why I do this, I have an external Nvme plugged into the dock with games installed on it). Simple and it works.

How many time have we all purchased as seen items only to test them (Ok not all people are mad), to find they are Not 40gps or not 3.2 USBC. This is a printed on the little fella. Used to extend Thunderbolt 4 on Mac to hub and kept all speeds.

Very well made and do the job.

Chciałem przedłużyć połączenie HUB na USB-C jednak po podłączeniu do kabla USB-C - USB-C 3.2 gen.2 nie wykrywa podłączonych urządzeń. Nie sprawdzałem czy działań ładowanie ale poszukiwaną funkcją było podłączenie replikatora portów.

Coupler works as expected, although I wasn't able to prove the 40Gbps speed or 100W charging

Used a fairikabe HDMI to USB C cable with power and this coupler to connect the Xreal USB C cable. Working great at 120hz. Video and Audio all good.
