The F500 Protector is the ultimate, multi-use survival tool. There’s a power bank for charging your phone. It also has an LED flashlight, a high-pitched alarm and strobe light. A built-in knife blade is designed for cutting through seatbelts and the cover on the end can be pulled aside to reveal a hammer that’s capable of smashing a car windshield with minor force. Less than the size of your iPhone, it’s a tool that can certainly save a life.
