PortaPow Data Blocker (USB-C)

Plugging your phone or laptop into a public USB port to charge seems innocent enough, but the truth is that public power sources can present risk. It’s possible for a threat actor to install malware onto your device and/or steal data via USB.

A simple way to prevent this is by using a USB Data Blocker. Simply fit it onto the end of your charging cable (the end that you plug into the power source), and you’re good to go.


  • Attach between your USB cable and charger to block data transfer/syncing. Charge mobile devices without risk of hacking/uploading viruses in cars, airports, etc.
  • PortaPow invented the first data blocker in 2013 and are now used by governments and corporations around the world.
  • Built in SmartCharge chip is compatible with Apple, Universal and Samsung standards to ensure it can charge your device at up to 2.4A
