USB cables have two purposes. The first one is data transfer and the second one is charging devices. USB Data Blockers or USB Condoms are devices that allow the charging of devices but prevent data transfer through the USB cable by blocking the data pins.

Juice Jacking is a way of stealing the entire data stored in your phone via the USB charging cable. When you use the USB port of public charging stations, you are granting the hackers to access all your data unknowingly. It is always better to have your own power bank and not to use the public charging stations for your mobile phones. But if you do need to use them, it is best to use a data blocker.

Best USB Data Blockers or USB Condoms

Connecting your devices to public networks, whether wired or wireless, is risky. Cybercriminals can steal your data. Now, since you are aware of this fact, you should be cautious while connecting your devices to networks like public Wi-Fis, cyber cafes, etc.

However, cybercriminals can steal your system’s data whenever you charge it using public USB charging posts through a technique called juice-jacking. The problem is that you would probably be caught unaware since you wouldn’t know this is also a method of stealing data.

This is where USB data blockers are useful. They block the data pins of the USB ports, allowing only power to flow.
