BUISAMG Data Blocker, 4-in-1 Universal USB Data Blocker, Protection from Illegal Downloading, Hacking Proof 100% Guaranteed, for iPhone 15 16 and Any USB Device Charging. 2-Pack

As advertised, would recommend and would get again. Well built, good handy devices to keep your data and devices safe and clean. Fits well, and charges as expected. Good items to keep your stuff safe. Dont just stick your junk into any old charging hole.

Nice data adapter for 4 in 1. It worked flawlessly for cell phone and laptop.

I travel quite a bit, and find the need to charge my phone in public places. For obvious security concerns (as we often read that hackers can steal your info over compromised public area connections), I make sure to add this data blocker to my charging cord, as added security. We have so much information on our cell phones, and keeping our data safe is a priority to most, if not all of us. I feel that this device works well to protect my information. I read somewhere that to test devices such as this, attach it to your personal computer, and you will see that the computer doesn't recognize your cellular phone. I did so, and indeed, the computer did not recognize (or "see") my cellular phone.

Good to have as have read about not using an unprotected charger in a rental car. Good to have at airports as well

The ATA 4-in-1 USB Data Blocker is a compact and reliable tool for safe charging on the go, offering strong compatibility with both USB-A and USB-C devices, including Android phones and iPads. It effectively blocks data transfer to protect against juice-jacking, though some users report a tight fit and variable build quality.

Components of the device came apart first time I attempted to use.

Apparently these data blockers are safe to use and they work at stopping any data transfer. My only minor complaint is the the male USB C ends are way too short If you have even a thin, light weight protective case on your cell phone, it is highly unlikely these ends will be long enough to securely fit into your cell phone's the USB C port. Just keep this in mind. Other than this, I would recommend them.

Thanks to this little device - my phone will finally play through my car Bluetooth when it’s simultaneously plugged into the power outlet. Thank you!!!
