Cable Matters 2-Pack USB C Extender Adapter, Up to [4K@240Hz Video, 240W Charging, 40Gbps Data Transfer], USBC Female to USBC Male Adapter, USB Type C Extender

It's silly and frustrating that I need this kind of adapter, but thankfully they do what I need them to do. I finally got a new tablet with USB-C last year and a USB-C flash drive. It makes transferring files onto the tablet easy, except that the case/cover on my ipad prevents the plug of the type-c flash drive from fitting. There's not a lip on the housing on the tiny flash drive that will give the plug enough clearance to get into the cut-out for the USB port on the case. It's the same for my phone; the usb-c flash drive just won't fit. From the look of it, this is a common design flaw in multiple brands of USB-C flash drives and lessened the usefulness. These cases on my tablet and phone are not at all convenient to take off when I need to use a flash drive. So for months I just resigned myself to not using them for that purpose. Then I pulled out an older, USB-A flash drive and tried it with a USB-A-to-C adapter I had, and the adapter had the clearance necessary to plug it in. Which was nice but USB-A is significantly slower to work with on a flash drive. Then i wondered if there was a Type-C-to-Type-C adapter I could use to similar effect, to give me a plug on my usb-c flash drives that would fit past the case and that led me to these adapters. And yes, they work! I can't speak to transfer speed benchmarks or whatever nitty-gritty details about performance. But anecdotally, they let me use my type-c flash drives with my ipad and my phone and the speed is what I would expect. It's really frustrating I need an extra adapter just to use a flash drive, but that's the reality. Thankfully these adapters are inexpensive and effective and useful and added value to the USB-C flash drive I own. So if you're main interest in this product is so you can use USB-C devices that don't fit past the case on your tablets/phones, I'd recommend it. It gets the job done.

Needed this to extend the USB-C connector on my iPhone 16 Pro when used in a cage with a wireless microphone. Fits and works perfectly!

As stated, I've been looking for a solution to the problem of how to supply power to my Huion Kamvas 13 Gen3 drawing tablet, which only accepts 5v 2a thru the recessed USB-C port, but most USB-C cables are too bulky to fit there. I didn't want to be tied down to one specific cable, and it's always the cable that wears out first, so I looked into getting an adapter like this. Thanks to another review on this listing saying that it fits the drawing tablet I recently got, I decided to try this product out, and I can happily report that the port extender provided fits very well into the recessed USB-C port that supplies power to the drawing tablet. It even looks good doing it! Now I don't have to be tied down to only buying the Huion proprietary cable, and I can do that in a way that is *mostly* compatible with the USB standards laid down by USB-IF (this adapter is not specifically standards compliant because it does not have an ID chip in it, but this is how it has to be since the things on both ends can only ever read one ID chip from one cable, meaning that extenders and adapters such as this are forced to omit the ID chip in order to remain "invisible" to the controllers on both ends). Anyways, now I can use any fast-charging USB cable I want as long as I put this port extender in line with the recessed port. The adapter does fit *very* snugly, but this is a good thing because it means that the plastic that forms the recess for the deep-set USB-C port is what will take any load from the cable, rather than the circuit board the port is soldered to inside the tablet. Because of this snug fit, I will advise that anyone who is having connection issues with this port extender to first try pushing the extender into the port more firmly, with roughly 5 pounds force (2kgf is close enough if you use metric, since there's 2.2 pounds to the kilogram). Once the adapter is fully seated, it should cause zero issues for you, it does not change pinouts, it does not have any pull down or pull up resistors, it is basically "just a dumb piece of wire" as far as the electronics on both ends are concerned, and that's a good thing. Seems durable enough to last a long time, but time will tell. Even if not, it's inexpensive enough that buying replacements isn't a huge deal.

Couldn't have asked for a better product! Cable Matters never disappoints! I needed to plug a USB into my phone but my phones case got in the way. I needed an extension/adapter that could get me the clearance I needed so it didn't have to remove my case. This did the job perfectly!

These are nice as they are small and work well. I have ordered twice as I needed more of them

It’s a nice extender for your phone and thermal camera.

These adapters work exactly as described. They let me use cords and accessories that previously wouldn’t fit with my phone case on, which saves a lot of hassle. The compact design is a big plus—easy to handle, not bulky, and they connect securely without feeling loose. The fact that it comes as a 2-pack is also convenient, since I can keep one at home and one in my bag. Great quality and very practical.

These little things works and is very high quality. It adds just the perfect amount of spacer between devices.

Impeccable ! Conforme

I just received this item and so I have not been able to use it more than a couple hours now. I bought this as an extension to a portable charger that wouldn't work with my Otterbox case. I chose this product for he step down design as I thought that it had a better chance of working with my phone case. The connection between the portable charger and the phone was very secure/tight to the point that I could pull on the charger and both the charger and the extension would come out of the phone - no need to remove them separately. Also, this is a portable charger and so when using the phone, I can confirm that the connection there is strong enough that there is no "sag" in the charger. There does not seem to be any issue with the charging speed.

Ho preso questi adattatori per risolvere un limite davvero fastidioso del mio setup video con iPhone: usando una gabbia Smallrig, il collegamento diretto al ProDock era praticamente impossibile. Con questi estensori finalmente riesco a collegare tutto senza stressare la porta USB-C e senza dover smontare mezzo rig. Costruzione molto solida e sensazione di qualità appena li si prende in mano. Supportano senza problemi alimentazione elevata e trasferimento dati stabile, cosa fondamentale quando registro clip in ProRes e ho bisogno di affidabilità assoluta. Non ho notato giochi strani o disconnessioni, e soprattutto mi hanno salvato un workflow che altrimenti sarebbe stato inutilizzabile. Non sono accessori “wow” a livello estetico, ma fanno esattamente quello che devono fare: risolvere un problema reale in modo semplice ed efficace. Per chi usa cage, hub o dock rigidi sono praticamente obbligatori. In breve: soluzione semplice ma fondamentale per chi ha setup complessi con iPhone e accessori USB-C, con qualche piccolo compromesso estetico ma tanta funzionalità. ✅ Pro • Permettono di usare dock e hub anche con gabbie montate • Costruzione robusta e connessione stabile • Supporto alimentazione e dati senza problemi • Ideali per workflow video professionali ❌ Contro • Aggiungono un piccolo ingombro visivo al setup • Non rigidissimi, quindi meno “puliti” esteticamente rispetto a un collegamento diretto

Para los usb-c Thunderbolt y distintos cables anchos, excelente sin pérdida de prestaciones y velocidad.

We bought these to extend us cables where they would not fit into my phone with the cover and they work perfectly and avoid having to find or purchase replacement use cables. Its a great purchase for the price as there are two in a pack
