PortaPow USB-A Data Blocker – Protect Against Juice Jacking (1, Transparent, 1)

I was going on a trip and knew that I might have to charge my phone and tablet from USB outlets, either at the airport, on the plane, or in the hotel.I have no idea how frequently juice-jacking (stealing the data in a phone/table/whatever through a charge cable) actually occurs. My guess is not very often, but why take the risk? I looked at several data blockers and, based on the reviews, bought these.I'm not a very trusting soul, so I also bought a USB cable tester to make sure the data would be blocked when using these. I tested each charge cable that I had, making sure that it would transmit data. I then repeated the test on each cable with one of these data blockers installed. Both of them blocked the data lines on the cables while still allowing the charging lines to connect. Good enough for me-- they went into my travel bag.In retrospect, I ended up not needing these. I was able to use my plug-in wall wart to charge my phone and tablet so my data was not in any danger. However, I like the option of having these in my travel bag in case I have to plug into some mystery USB jack and not worry. For the price, I consider these essential for travel.

Very easy to use, just plug and that's it! It easily fits any pocket, has a good and sturdy build quality, and the most important thing, it blocks transfer of data. It doesn't hinder the charging speed in my experience. Best to use in airplanes and hotels.

Just in case I have to recharge my mobile at the airport on a public plugin: I feel safe that my data is not being stolen.

We used these recently while traveling and were able to charge a phone with no worries about hacking or stolen info.

Excellent internet security precaution - so delighted my wife learned about it and gifted me one.

The great thing is that you can see that the two center data pins are missing and not connected. The data protection is visible. If you buy one of the competitors, you would have to use a multimeter to test continuity between the center data contact points of USB.

I use these for my car dashcams, and they have been a game-changer. Previously, my cameras would occasionally switch to data mode even though they were connected to power only. Since I started using this product, that issue has completely stopped. It provides a stable and reliable power connection, ensuring my dashcams function correctly at all times. Highly recommended for anyone facing similar issues!
