Which USB Data Blocker do I need?
Not sure which connection you need? Choose the option that matches your device and charging port.
The USB data blocker physically prevents any data transfer between your device and the host port (e.g., public charging station, unknown computer). It only allows power to flow through, ensuring your device charges securely without risk of data breaches, malware injection, or unwanted syncing.
USB hacking, often referred to as juice jacking, is a cyber threat in which malware is installed or data is secretly copied from a mobile device via a compromised public charging station.
A related term, choice jacking, specifically refers to a more advanced form of juice jacking where attackers manipulate the "USB connection type" prompt on your device (e.g., "Charge only," "File transfer") to trick you into granting unauthorised access.
A USB Data Blocker is recommended whenever you charge your device using public, shared or untrusted USB port - anywhere the source of the connection isn’t fully verified.
This includes places such as airports, hotels, cafés, conference centres, co-working spaces, libraries, or public transport hubs. It’s also useful when charging in rental cars, shared offices, or through another person’s computer or power bank.
In these environments, USB ports can be tampered with or used to install malware or extract data; a USB Data Blocker prevents that by allowing power to flow while blocking all data transfer.
You can find a simple demonstration video on the product page. This test can be performed anywhere and all you need is a phone and laptop.
If you connect your phone without data blocker, you will notice your phone will attempt to connect to the laptop (it might ask for permission or connect without a prompt).
If you repeat this test with a data blocker connected, you'll see the phone is still charging, but is no longer attempt to connect to your laptop.
Yes, our USB Data Blockers are compatible with all devices that use a standard USB-A or USB-C charging point. Devices that can be protected with a USB Data Blocker include phones, laptops, tablets, cameras and even drones.
The USB-A to USB-C data blocker only prevents data transfer and doesn't impact charging capacity. If your USB-C device isn't charging, or is charging slowly, the USB-A port likely isn't supplying sufficient power for that device's needs.
Charging speed depends on the power output of a USB-A port. Some older USB-A ports only provide a small amount of power (around 500mA). This may not be enough for the charging chipset inside the Data Blocker Pro to work properly. The chipset is designed to enable fast charging, but if the power supply is too weak, it may prevent any power from passing through at all.
You can plug the data blocker into either your device or the USB charging port. While both configurations work, we recommend plugging the data blocker into the USB charging port.
Tthat is generally more convenient than having the data blocker connected directly to your device and provides consistent protection for all devices you might connect to that power source.
