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

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.

Works perfectly as a USB-C extender. I own an Otterbox Defender case and one of my new products I bought, the usb-c end is too short to fit into the port. These Cable Matters USB-C extenders fit in the opening perfectly, giving me enough room to connect my new device to my phone. These also work great if you have tight USB-C ports on your computer too.

These are great, just don't sit on them with your phone in your pocket. I have suffered two casualties this quarter. Luckily the piece of tech I've been adapting has survived.

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.

Cable Matters quality! Works well.

These USB C extentions does what the manufacturer states in the description of the items. To extend the USB C port of any device this adapter is plugged into. It snuggly fits both the input USB C port of the cellphone/tablet/game device(s) & accepts the split or combined data & power usage through multiple OTG adapters & other USB C devices. Basically it is an "invisable" extension of whatever USB C device the user deems necessary to complete their desired function at the time. I just got a "new" Samsung Galaxy S21 Ultra. Which does not have an internal MicroSD slot available anymore after Galaxy S-series S20 model phones. So I use these for extending my OTG USB C to USB A 3.0 & a PD100 USB C to power my phone & external device(s) that I want to use with my phone. These little guys allow me to keep my case on my device while utilizing my OTG adapters with the shorter USB C male plugs. I bought two sets of these because I can leave them plugged into the OTG devices I use the most. Since they are built out of metal these USB port extenders are worth the few dollars & save you lots of headaches of dismantling your phone case or not being able to use that hard to get to port on the back of your notebook or game device. Cheers!

I bought this extension for an iPad case that had such a small opening for the charge port that I could not connect a 90 degree USB-C cable to it. For this it works well. However it stuck out far enough that it can put strain on the connector. I noticed the other way when I went to change the iPad that the adapter was slightly bent. Had not affected the port as far as I can tell, but this worried me enough that I ended removing it, and instead opened to modify my iPad case so the cable will fit. It’s not elegant but it’s also not horrible and it works better now that I don’t need the adapter.

Good cable. As advertised.

Impeccable ! Conforme

Bien, cumplen su funcion, se ajustan correctamente a la ranura.

Passt und funktioniert.

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

Excellent extension. Well made, functions perfect when tested with multiple devices.
