Generic Data Blocker, USB A to C & USB C to C (4-Pack), Protect Against Juice Jacking, 100% Guaranteed Prevent Hacker Attack, Support Safe Fast Charging up to 20V/4A

Never knew we needed this if you’re plugging into power from an unknown source while traveling get this so your contents on your phone isn’t hacked & stolen. Not sure this is a real problem but I’m not taking that chance.

I just tested these devices; the USB A-C is OK with 1.1 amps, but the USB C-C is worthless at 0.1 to 0.0 amps.If you want the USB C-C device, don't bother.

I really like these devices, it keeps your devices safe!

This will block your data but may not be compatible with every charger that is able to negotiate quick charging protocol s. While I have not tested on every quick charger that I own. I have tested it with on on most of them that I own. The primary purpose is to be able the use a publicly available charger without out data being sent. It does that. Will you be able to take advantage of a public quick charger, maybe. Would I buy again or give the to a friend or family member to use while traveling Yes.

Good protection for charging phones and tablets.

Plugged these on my cord to charge my phone at the airport and I bet they do block the data because they blocked everything including power which is what I needed them for but I had to resolve to just using my cord without any protection. It did work once into these things off. I tried both. My wife tried both and the are a complete lady if money.

I'd like them

The items do not work. Placed the Data blocker in my phone phone cant charge with it.\CRAP!
