Afterplug USB C to C Data Blocker, Anti Juice Jacking, for Charge Only, Case Friendly Design, Support up to 240W PD Charging (2-Pack), Red

They work great! we use them in a car which gets confused as to which phone to talk to when both are plugged in -it's easier than going through the menus to change phones. It's also good to use when plugging into an unknown USB to charge - it makes sure that your phone isn't compromised either accidentally or on purpose.

These are as advertised. They work flawlessly and are plug and play. Great little added protection.

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.

The adapter does block all digital signals. That means it blocks the handshake for USB-C PD so when this is plugged in my iPhone 15Pro, it defaults to 5v 2.1amps for charging regardless of what charger is capable of. For a "charging only cable" this is super disappointing. I only use it on public USB ports when I have the time for a slow charge.

Works as expected. Red makes them easy to distinguish. Used to charge phone from a laptop and prevent sharing data.

It's a very good item, just add it to the end of an UBS C cord that you have for your phones and plug it in

I bought four of these and two of them have detached the metal part that sticks out. The plugs were not under stress and they were pulled out by the red portion of the attachment. I can only blame poor quality manufacturing. A shame since they did seem to stop data transfer. I don't recommend purchase as they did not last long because of the defect

Works well
