UsbSafe²: an open, programmable dongle for protecting USB devices from USB hosts and chargers

Always stay secure and protect your private data and gadgets when connected via USB. USB connections transfer information and power. UsbSafe² is a device that protects USB-connected hardware from excessive voltage, current, and unauthorized data access. Unfortunately, the practice of “juicing” (accessing data from devices connected to public charging stations) has become very common. UsbSafe² offers a unique combination of anti-juicing mode and fail-power protection. With UsbSafe², you'll feel safer no matter where you are or what you plug in, your valuable gadgets are protected and secured!

USBSafe² provides two types of protection: data security and overpower protection. You have complete control over the power going into your device. Overvoltage protection (OVP) ensures that your hardware is never exposed to voltages higher than 6.5 V. Current protection offers five selectable levels that can be set with the push of a button. UsbSafe² disables the device's power output if a high voltage or high current condition is detected. By enabling data integrity mode, Juice Jacking will not be possible and your private data is protected.
