Ztylus says the Stinger is a USB car charger that can save your life. And not just figuratively when you're on your last 8% and get a very promising hit on Tinder. In addition to the dual USB ports fed by your car's cigarette lighter, this combo tool has the literal life-saving features of a spring-loaded window punch and seatbelt cutter to help you escape from your vehicle in an emergency.
Ztylus points out that combining these emergency tools with the high-speed charger elements helps ensure the Stinger will always be within grasp when you need it. No digging around in a glove box that's potentially out of reach, or out of commission after a collision.
