USB Data Blocker -Protect Against Juice Jacking,Hack Proof 100% Guaranteed, Protection from Illegal Downloading, Any Other USB Device Charging, Data Blocker, 2-Pack

We used these data blockers in two airports to recharge our phones and iPads. The items appear to have worked as advertised. I am very happy with the quality, performance, and price for this item. I would definitely buy them again.

And get some more while you’re at it

I just got this two-pack, it was around the least expensive option and have the most reviews and highest star rating, so I went with it.And, we’ll, it does exactly what it says it does. So in those respects, it’s worth buying if you have privacy concerns plugging into public USB ports or, like me, just want your darn car to shut up about how many tracks are on my iPhone every time I get into my car and be sure I only make calls/stream music with Bluetooth (unfortunately for me, the power outlets in my car NEVER shut off if anything is plugged into them, so I went with this workaround).They DO look cheap, and maybe they are, but I won’t be plugging in/out much if ever, and I got a backup in case one should fail.I’ll update on durability after some use. But for the price, go for it.

Serves its purpose.

I purchased these data blocker to take with me when I travel. I travel frequently and worry about malware having been loaded onto public charging stations. With these blockers I won't have to worry about charging my cell phone in public places. Better safe than sorry.

Pardon the crumbs. But this worked to solve the annoying problem of my car detecting an iPod when trying to charge my phone and messing up the existing Bluetooth connection.

Lol if you think about it, will you ever know if these really work? No idea. But i use them for airports and it doesn’t change the charge so.. theres that

The photo on Amazon shows two pieces but I got three. I assume the two bigger pieces are the data blockers, although I have no way of verifying that they do the job, but what is the little piece? It appears to be USB-C but I am not sure what it is for. Can someone enlighten me please? Also, I see no evidence that these are actually data blockers. I don't see an absence of wires in the middle.
