    Excellent.
    Good product and good value. This is a well made adapter that sits securely in the USB port. No slowdown in transfer or connection speed and has been compatible with everything I have tried it with.

    Very useful when you have a phone case
    I have an iPhone case, and the extender is handy for attaching items like the Rode Wireless Micro.

    Connection made.
    I bought a ‘robust’ case for my new phone. So chunky, that one specific cable (for a printer) won’t fit. This is just what I needed to make the connection. Quality build.

    Bad Design; Rubbish/Poor Quality; Did NOT Work!
    Rubbish; Flawed; Did not workLooks rugged and pretty; but poor quality Inside! Outside beauty is of no use in such a device.List of Problems:-Did NOT work; tried various Type-C connectors on different devices; with different cables-Serious Design Issues (after trying with several male cables; female sockets):– Male connector is Longer than necessary– It does NOT click; so you do not know when it is seated– The Black middle part makes the connector longer– Overall, the connector is TOO long; it should be around 40% shorter; it sticks out so much that it could easy bump into another surface, and it could damage the Female socket in your device, phone, computer, laptop; thereby rendering your device useless (those female connectors on your device are mounted on the main board; would require factory-repair and would be costly, if damaged by this connector)I returned these connectors within a day!

    I bought this for my huion tablet. It has a port that fits very few cables and I bought this instead of a replacement cable from their website. It works perfectly for my kanvas 13 and makes my tablet way more versatile as it now works with multiple cables. Would definitely recommend

    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.

    Ich benutze den Adapter für den Anschluss eines USB Sticks an ein Iphone mit Hülle. Der USB Stick lässt sich ohne diesen Adapter nich weit genug in die Buschse des Handys einführen, da die Schutzhülle des Handys ziemlich aufträgt. Mit diesem Adapter ist das Problem nun gelöst. TOP!
