USB Data Blocker Pro Travel Pack
$24.95
Stay protected wherever you charge with the SecurityBase USB Data Blocker Pro 3-Pack. Built with a durable aluminium alloy design, they are designed to protect your devices from juice jacking, unwanted data transfer, malware risks and data theft. These compact adapters create a secure charge-only connection in every charging scenario.
This set includes three types, giving you flexible protection across all charging setups: 1 x USB-A to USB-A, 1 x USB-C to USB-C & 1 x USB-A to USB-C Data Blocker Pro.
How the USB Data Blocker Pro Works
Each adapter in this USB Data Blocker Bundle contains a built-in chip that electronically disables the data lines while preserving the power connection. When you connect your device through one of these blockers, only the charging pins are active, meaning your device can draw power without exposing its data.
This chip-based approach offers a smarter alternative to physically modified data blockers, ensuring stable, charge-only connections without interfering with charging speeds. Whether you're using USB-A or USB-C, the blockers act as a secure barrier between your device and any data transfer attempt, maintaining privacy and data integrity during everyday charging.
The result is a simple, hardware-based solution for protecting your device whenever you plug into a new or unfamiliar USB port.

USB Data Blockers - FAQ
-
A USB data blocker adaptor works by creating a physical barrier between your device and the USB port you're plugging into. Here's how they work:
- Targeted Functionality: The blocker focuses on the specific pins within a USB port that are dedicated to data transfer. These are typically designated as D+ and D-.
- Selective Blocking: The blocker's circuitry is designed to disable these data transfer pins entirely. This prevents any exchange of information between your device and the USB port.
- Power Delivery Unaffected: While data transfer is blocked, the blocker allows the power (V+ and GND pins) to flow freely. This ensures your device receives the necessary charge to power up.
-
Our USB Data Blockers Pro support common fast charging protocols like Quick Charge and Power Delivery. This ensures compatibility with various devices and fast charging speeds up to 48V/6A.
They are essentially small adapters with circuitry that blocks data transfer while allowing power to pass through. This process shouldn't interfere with the charging current, meaning your devices should charge at their intended speeds.
The slim USB Data Blocker 2.0 is our entry level model, which, uses a different method where the data circuit is completely removed. This can slightly impact the charging speed, often resulting in slower charging times compared to direct connection, similar to charging from a standard computer USB port.

A USB data blocker primarily protects against two threats:
Data Theft: When you plug your device into a public USB port, there's a risk that malicious software on the computer connected to the port could try to steal your data. This could include sensitive information like photos, contacts, financial information, or even work documents. A data blocker acts as a barrier, preventing any data transfer from your device to the computer.
Malware Infection: Similarly, a compromised USB port could be used to install malware onto your device. This malware could then steal your data, track your activity, or even damage your device. A data blocker helps prevent this by stopping any malicious software from entering your device through the USB port. A USB data blocker primarily protects against two threats:
-
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.
-
Our data blockers work bidirectionally to block data transfer. Whether it's connected directly to a USB port or to your phone/device, the data lines will be effectively blocked. As long as the data blocker is connected between your device and the USB port of the power source, your data will be protected.
