What Is PAW Protector?
Public USB chargers, at airports, cafes, and rental cars, can do more than charge your phone. The same cable can carry data, and someone could use that connection to read your files or install malware without you noticing. This is called “juice jacking.”
PAW Protector stops it. Plug it between your cable and the public charger, and it physically blocks the data wires, so only power gets through. Your phone still charges at full speed, up to 2.4A, the same as normal.
There is nothing to set up. No app, no pairing, no buttons. In testing, a phone stopped being recognized as a data device the moment PAW Protector was connected, proof the data path was closed, while charging speed stayed the same.
Charging Safely at the Airport, Cafe, or Anywhere Public
