How the USB-A to USB-C Data Blocker Works
This USB-A to USB-C Data Blocker securely connects USB-C devices to older USB-A charging ports while preventing any data transfer. It features an integrated smart chip that blocks data exchange, protecting your phone, tablet, or other USB-C devices from juice jacking, data theft, and unauthorised sync attempts when using public or untrusted USB-A ports.
While it allows for safe charging only, it's important to note that some USB-A ports supply lower power output. As a result, charging high-powered devices like laptops or tablets may be slower or unsupported when using this adapter with older USB-A power sources.
This compact USB-A to USB-C charge-only adapter is ideal for travel, workplace use, and everyday security, ensuring peace of mind when plugging into unknown charging stations, without compromising your device’s data integrity.
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:

Security Professionals: (Cyber Security Experts, government agencies, law enforcement, and intelligence personnel handling sensitive data.
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.

USB data blockers are highly recommended in situations where you charge your devices in public or potentially compromised locations, such as:
- Airports & Train Stations
- Cafes & Coffee Shops
- Hotels & Conference Centers
- Libraries & Public Spaces
- Co-working Spaces
- Public Transportation (buses, trains, subways)
- Rental Cars
- Shared Offices
- Public Computers
- Any location with unknown or unsecured charging ports

Our data blockers work bidirectionally to block data transfer. Whether it's connected directly to a USB port of the to your phone/device, the data lines will be effectively blocked. As long as the data blocker is inline between your device and the USB port of the power source, your data will be protected.
