How the USB Data Blocker Bundle 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 cables, ensuring stable, charge-only connections without interfering with device performance. Whether you're using USB-A or USB-C, the blockers act as a secure barrier between your device and any data transfer attempt — helping to maintain privacy and data integrityduring 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 Pro type USB Data Blockers support common fast charging protocols like Quick Charge and Power Delivery. This ensures compatibility with various devices and fast charging speeds up to 50V/5A.
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 slighly 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:

Government travelers on official duty: When traveling for official business, government employees frequently need to charge their devices in various locations, including hotels, conference centers, and airport lounges.
People who work remotely or travel for business: If you're constantly on the move, you may find yourself charging your devices in a variety of locations. A USB data blocker can help protect your sensitive data, such as work files or financial information.
Anyone concerned about data security: Even if you don't travel frequently, using public USB ports can still pose a risk. A USB data blocker is a simple and effective way to add an extra layer of security to your devices.
