This car charger is a lifesaver. No, not because it’ll power your phone when you’re desperately low on battery and you need to use Google Maps… but actually because this bad-boy is your ticket to surviving a car crash. While the Ztylus Stinger serves its purpose as a car charger with two 2.4 ampere USB ports , it also includes a spring-loaded glass breaker and a seat-belt cutter hidden away in its incredible design. The spring-loaded glass breaker is actually concealed within the charging pin itself. Just grab the charger tightly and press it firmly against the glass. The spring triggers the breaking pin and the glass shatters instantly without the need of any force or even repeated striking. The Seat-belt cutter’s blade is placed strategically to ensure you just cut the belt and not yourself. The blade is incredibly sharp and slices through the belt’s fabric like a knife through butter. It’s incredible how a simple idea can give a product a dual purpose, and quite a useful one that too. The magic is that the charger is ergonomically perfect and always accessible. Wonderful! Designer: Tim Hsu of Ztylus Innovation Designed to avoid entrapment within a vehicle after experiencing a car accident. The spring loaded punch works easily and quickly to give you the best chance for escaping your vehicle. Designed to help you cut your seat belt if you find yourself unable to release it normally. The blade is protected to prevent accidental injury to yourself and has been tested on a 5000 lbs towing strap so you can be sure it works if you are in an emergency. Their unique innovation doubles as a dual USB port charger, which plugs into your car charger for high speed charging. It features an intelligent circuit design to protect against short circuiting, over-heating, over-currents and over-charging.
