USB-C to USB-C Data Blocker, Anti Juice Jacking, for Charge-Only, Supports up to 240W PD Charging (2-Pack), Red

Worked exactly as advertised. Charges the phone while keeping data secure. Will not fast charge though, which product description does warn about but I don't mind that as much.

I'm very happy with these data blocking plugs. They pass full power. I can see >50 watt charging to my computer with my power meter. When I plug into my computer with the adapter, the computer doesn't see my phone connect, so it's blocking data. These plugs are nice and small and bright red. Easy to find in your kit.

These plugs do their job. I always use them in airports, hotels and airplanes. They are easy to use and give me just the power to charge my cell phone or tablet and nothing more. A good item to have when you are in unfamiliar places needing to charge and you don't have the concern that else could be sent to your phone.

I got these so I could safely use my cable to charge my phone when at the airport or on the airplane. I generally use a powerbank, but one time I forgot to pack it, and was very hesitant about having to use my charging block at the airport. But now with this, I can keep my powerbank as a backup, and use this data blocked to charge via cable. I tested this by first plugging my phone via cable to my computer, which allows me access to the files on my phone. I then plugged the cable into this connector and then plugged it into my computer, and confirmed that I was no longer able to access my phone's files. I also confirmed that it does not matter which end of the cable you plug the connector, it will block data transfer every time. It is so easy to use by keeping it plugged into a cable just for travelling and the right angle makes it more comfortable to use from your airplane seat, as it juts out less. I have been recommended this to all everyone since and personally feel this is a must have for when you travel!

Bought this as protection against juice jacking should I plug into an unknown charging port. Seems to do what it says. Allows fast PD charging but blocks data. Tried to connect to my MAC with this inline, and it could not connect. removed it and tried again, and phone connected to Mac just fine. Seems to block data lines. An extra layer of protection should you decide to plug into an unfamiliar charging port. Didn't seem to reduce charging time/speed or capacity. nice to have in your travel kit.

works great

Not only are these ADORABLE, but nowadays they can be a life-saver in a pinch. Keep a few in your bag or purse so that they are with you when you travel. They are so small in fact, I wouldn't doubt if some folks could keep one in their wallet comfortably. If you fly a lot you should absolutely invest in these. Public chargers, while convenient, are a breeding ground for malicious hacking activity. When you plug your phone into something, it could potentially be transferring your data as well! These adapters prevent that, essentially dumbing down the cable so that it can only pass power through, not any data. This allows you to get the charge you want without the risk of data theft. If you are smart enough to not plug into those public chargers and instead carry your own, these are still handy for troubleshooting, or even to loan out to the person sitting next to you if they are unaware of the dangers posed. Ultimately I will be buying more of these to keep on hand for this purpose.

Didn't work. My phone charged at a trickle compared to the regular charging speed - about 25% of the regular speed.

La charge rapide fonctionne, l'ordinateur ne détecte pas le téléphone branché, c'est parfait !

It does block the transmission of data, but also degrades the charging power passing through it. This is a product that is not worth investing in. This is an update to my previous writeup following the response from the seller: This data blocker does allow fast charging of mobile phones provided a USB type-c to type-a cable in not used. I have upgraded the review to a 5-star as I was able to fast charge my phone using a type-c to type-c USB cable as instructed by the seller.

Tested with cable tester and confirmed that it blocks out D+ and D- pins, only allows Gnd, vbus, and CC1/CC2 to pass through. Don't have any high speed transfer cables to test with though. All 24 pins on the male and female side of the data blockers are also present, so unless someone is willing to send a high-speed USB-C to USB-C cable my way, we will have to take the manufacturer's word for it. I also tested charging it up to 40W without any issues, although the data blocker did get slightly warm after 10mins. The metal enclosure helped in the heat dissipation. I guess the size is also made intentionally small so it can be kept together with any charging cable, but I personally would have preferred it to be bigger or have a loop I can attach a Keychain to so that I would misplace it easily.

Funktionieren leise und ohne Probleme.
