Data Blocker, USB A & USB C Data Blocker for Any USB C Mobile Phone Quick Charge, Protect Against Juice Jacking, Refuse Hacking, Only Safe Charging. (4-Pack) (Red)

I use this in my car when charging my phone. Dont want the data from car down loading onto my phone. And it works! Also good for when I'm traveling in a friend's car and need to charge my phone.

Very useful when charging outside one's home. Protects the person's privacy on their devices when using public computers.

I don't always take a power bank with me now... even when I do, I no longer worry about recharging my devices. Also now assured data transfers are secure.These are easy to use, small item - used at airport, on plane, public areas, hotels. Must be effective as I've not had issues.

If you've ever had your identity stolen (I have!), these are a basic MUST HAVE!Identity theft may make for a funny movie, but the bottom line is that financially, it CAN cost you the "bottom line". YOUR bottom line!Based on my personal learning experience, every USB charging cable I own has one of these attatched, my modem AND router cables "wear" them. And my printers are bonded to them. ANYTHING that does automatic downloads from the web can be hacked easily.If you think I'm being an alarmist, I look at things this way: What is the cost of a BUCKETFUL of these compared to the value of my (or YOUR) financial "bottom line?"I'm still shopping for a "bucketfull." Getting closer!

Got these today to block data on my car cam power cord works perfectly

Just what I needed

This data blocker is a very important tool to preclude data compromise while traveling, but it needs to be labeled as such! Looking like a normal USB-A to USB-C adapter, it could taken to a business meeting for data transfer, then leave you guessing at why it isn't working. It looks sturdy and works perfectly, but I am rating it down because of this risky deficiency.

nice to have handy
