Review on PortaPow USB Data Blocker (5 Pack, Black) - Safeguard Against Juice Jacking by Travis Flores

As a data blocker in conjunction with my iPhone XMax, the product works as advertised. I tested each of the 5 devices individually by connecting them to a desktop computer using an Apple USB data/charge cable. When trying to back up my phone data, the data stopped transferring. My iPhone wasn't even recognized, but my phone battery was still charging. I made this purchase primarily to avoid data breaches and malware at public charging stations like airports. I did my test and the data blocker works. Now I have peace. Inexpensive 5-pack (compared to buying them individually) to share with family and friends.
