BUISAMG Data Blocker, 3-in-1 USB Data Blocker, Prevent Illegal Downloads | data blockier Prevent Hacking, for iPhone 17 16 15 and Any USB Device Charging.2-Pack

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.

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

Read that hackers are dealing data when you used chargers in airports. Using them makes me feel safer. I cannot speak to how well they work. But, I haven’t been hacked.

as described

These do not work. Data does not transmit at all. Devices will not charge through these devices.

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!!!

Bueno

Convenient to have USB and USBC together. Bright red to mark as charge only. Good quality and value.

I learned about this from an ethical hacker interviewed on PBD on Valuetainments Bet-David Show - YouTube. My favourite American Entrepreneurs. The future looks bright. It works. I'm a safety gal.

This is a very useful data protection usb connector to have in your computer toolkit, you never know when you’ll need it

Tested it under various scenarios and cables and it charges and blocks data connection
