Protect yourself from BadUSB while charging at full speed. USB Power Armor blocks USB data communication, but still allows devices and chargers to negotiate power levels. Simply plug a USB Power Armor in-line with your charging cable. To learn more how it works, click here.

Note: If your device uses USB data to negotiate power, the Power Armor will block that. My testing shows that the iPhone uses this method to get more power from desktop USB ports. So iPhone plus computer will charge at 100 mA. However, iPhone plus wall adapter has charged at full speed in testing so far.
