JSAUX USB Data Blocker (2x USB-A + 2x USB-C)

The JSAUX USB Data Blocker solves one of the most underestimated digital privacy risks when traveling: data theft through public USB charging ports (juice jacking).

When you connect your phone to charging stations in airports, hotels, trains, or shopping centers, you are not only receiving power — you may also be opening a data connection. This could potentially allow:

• unauthorized access to files

• malware or spyware installation

• unwanted data transfer requests

• device compromise

This device physically blocks data transfer while allowing charging only, providing a simple hardware-based security layer.

It allows you to:

• charge devices safely anywhere

• avoid hacking attempts through public USB ports

• prevent malware and spyware risks during charging

• eliminate unwanted data transfer pop-ups

• protect personal information and files

• travel with greater digital security
