Remember kids. Always wear your #USB condoms when plugging directly to a random usb port for charging stuff. You don't want your data pins to be accessed in case of a compromised USB port. Stay safe out there! What this red appliance does is block data from going through the USB connector and only power to pass. This way you can charge and be confident that nobody is accessing information from your device. Never connect directly to wall USB ports. #safety #safetyfirst #technology #nerd #airportlife #cybersecurity #hack
