Plugable USB Data Blocker (USB-MC1)

The Plugable USB-MC1 Data Blocker is a compact security adapter that converts any USB data port into a charge-only port, effectively blocking juice jacking attacks. Whether you're at an airport, coffee shop, or library, this tiny adapter—smaller than a pack of chewing gum—ensures your devices only receive power, not data, when you plug into public charging stations. It works with all USB devices and is a must-have for travelers and remote workers who prioritize security.

Protect Your Data with Plugable USB-MC1

Designed to slide effortlessly into your pocket or travel bag, the USB-MC1 provides peace of mind while charging on the go. Simply plug the blocker into a USB port, then connect your charging cable to it. It physically isolates the data pins, so malicious chargers can't access your device. The adapter is compatible with all USB devices, including iPhones, iPads, Android smartphones, and any device that charges via USB.

Fast Charging Compatibility

While the USB-MC1 blocks data, it allows full power delivery, so you can still charge at the speed your device supports. Many users wonder if fast charging is possible—yes, the blocker passes through current up to the limit of the charging port, typically 2.4A or higher for fast charging. However, note that some proprietary fast-charging standards (such as Qualcomm Quick Charge) may still work if the charger and device negotiate power through the power lines, which the blocker does not interfere with.

For users concerned about data security without sacrificing charging speed, the Plugable USB-MC1 is an elegant solution. Its durable construction and simple design make it a reliable everyday accessory for privacy-conscious professionals.
