Duttek USB C Coupler 40Gbps, USB C Female to Female Coupler supports 8k@60HZ and 100W fast charging, Type C Adapter 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

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.

It actually works with dell thunderbolt 4 hub but its side sensitive that's probably why some people find its not working. It's usb4 only difference is not thunderbolt certified but should have full functionality with thunderbolt 4 device. One star is reduced for its side sensitive.

Very well made and do the job.

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.

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.

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.

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.
