USB-C to C Data Blocker

These work perfectly for allowing one to connect a device to any random USB-C port they come across without worrying about someone being able to hijack the data on the device. Now SHOULD one connect to a random USB-C port for charging? Not if you can avoid it but sometimes circumstances just dictate that you have to do so. This cable is for that situation. It provides power to your device while interrupting the data lines so that a suspicious host device cannot steal or mess with your data. I've used equipment from PortaPow for a few years now and never had any issues with them. Running some simple tests with simple test equipment and my phone and tablet I noted that I was able to negotiate a high(er?) charging rate than I would have had with just a 2-wire power connection. This seems to indicate that there is enough "smarts" in the cable to ensure better-than-minimum charge rates. Although YMMV as I see various reviews that certain devices could not negotiate the higher charge rates. Not having access to a full test suite I can only report that--for my own uses--they work fine and are from a company I trust.

USB C uses data to figure out if it can send more power. When I use this to charge phone or other devices its a slower charge, but I also know no data is being sent. Pros and cons. Solid product from a solid company, as always.

Used on two extendend overseas trips. I was able to keep my phone charged in aircraft and during airport layovers without risking my data. Well made. The red makes them stand out in a backpack or carryon pocket, and less likely to be left behind. (With any data blocker, test it to ensure it actually blocks data connection. Connect your phone with your computer and see if the computer lists it as another device.)

I tested this on my USB cable tester attached to a full featured USB C to C cable. It does appear to block all USB data lines, as well as the sideband lines and one of the config lines. These last two seem somewhat unnecessary, and it's probably why the cable seems to also block all charging when connected onto the end of an "E-Marker" cable. Apparently most of the cables I own contain E-Markers except for one short one. Through this I was able to charge and the USB-PB voltages were apparently able to be negotiated. It also seemed to work on the end of a USB A to C cable. So it "works", but as a practical matter I'm not sure how useful this is in the real world.

Bought these for traveling and rental car use to keep my phone data safe, and they work perfectly! Every time I plug my phone in to a rental car with this cable, my phone yells at me to make sure the cables are connected properly because data isn't transferring - and that's a reassurance I love to see! The best part is that this adapter allows my phone to charge just as fast as my cable that plugs into it would. I tried connecting my phone through this adapter to my two different laptops and I couldn't find the phone on either, plus no car can find it, so I would say these work as intended. This adapter essentially works by breaking the data link between a data-enabled power cable and whatever it is plugged into because the adapter does not contain the middle data transfer pins. Unfortunately not many charging cables come without data transfer pins anymore, so now we need to spend extra for this protection. As frustrating as it is to spend more money for a cable/adapter that does less, the piece of mind is worth every penny.

My data blocker cable failed to function on its first use — I could not charge any item connected to a power source through it. Multiple tests with different wall plugs, charging ports, and USB-C cables showed that this item was the failure point. There is a disappointing lack of quality assurance evident in this product.

Great data blocker to make sure your protected from data jacking from rogue ports good value for the money, really easy to use. Great that it’s red prevents loss.

Works for me as intended. Useful for charging anonymously. Critically, by blocking the data signal, these adapters enable use of data-enabled entertainment system USB ports for operating and charging dashcams and GPS navigators that otherwise go into upload/download mode using these ports. Don’t want to upload your entire contact list to that rental car? Then get this! Highly recommended.

It's a great way to safeguard your phone while charging in unfamiliar locations.

Si collega saldamente al cavetto di ricarica, ed evita possibili contaminazioni del dispositivo da parte di fonti di ricarica non conosciute o insicure.

Ha llegado rápido, lo compré para evitar que al cargar móvil me roben datos, su función sería antimalware

時々外回りをする仕事をしていて、たまに海外旅行もします。 駅前のコワーキングスペースのような場所でPCを充電したり、海外の空港の充電ステーションでやむを得ずスマホを充電しなければならない時、「ここにケーブル挿して本当に大丈夫かな…？」とふと思うことがありました。このケーブルがあれば、ひとまず安心感を得られます。 小さいのでガジェットポーチに追加しても全く邪魔になりません。 強いて言えば、受け側のポートがちょっと浅いのでケーブルが抜けそうになる点は気になると言えば気になりますが、安全には代えがたいとおもってます。

Does what I says it should! 👍🏻
