Review on PortaPow USB Data Blocker (Black) - Secure Against Juice Jacking Safely by Travis Karren

I bought this while traveling to ensure my phone/laptop didn't get infected when charging via USB connection in a public place. Basically I'm using it at the moment to charge my Kindle and iPhone from my computer (easier access in my office) and not have them connected to my computer (which I very rarely want and it just annoys me when I say need that I'm not supposed to connect - I know, too lazy, but since I still have that key I can use it).
