Review on 🔒 Enhanced PortaPow USB Data Blocker (Red) - Ultimate Protection against Juice Jacking by Deandre Vogt

Product works exactly as described and seems reliable and should last a long time. I've had several chargers advertised as 2.1A, but none of them could charge my iPhone 6 Plus or iPad fast enough. I daisy chained this product and using the USB Power Monitor sold by the same company I could see a current increase from 0.48 amps to 1.89 amps on one device. It did NOT work with my BMW 3 Series (2014 model year). I was hoping it would speed up this charging process as well, but either the car snapped or the iPhone didn't like the whole thing and the charger would cycle on and off rapidly until I quickly yanked it out. Another reviewer said it works fine with the car and in theory it should, but that part didn't work for me. Overall I'm still satisfied as it does exactly what I need it to do on some of the other key charging ports.
