It’s late at night at the end of a long training run. Suddenly, a man bursts from behind a tree intent on mugging you.
Fortunately, you’ve got your iPhone and it’s not just for calling the cops. A new iPhone case from Yellow Jacket doubles as a stun gun capable of knocking an assailant to the ground with a high voltage charge emitted from two prongs on one end.
The tough plastic case houses an external battery that can also nearly double the life of your phone battery. The case is charged by simply plugging your phone into its charger.
The Yellow Jacket is available now from the company for iPhone 4 and 4s with a .8 mA battery for $99. It’s coming for iPhone 5 and 5s with a sleeker looking design and 1.3 mA battery in February for $150.
Safety features help prevent accidental discharge. It has a safety switch, and before you use it you have to flip off a sturdy cover to deliver a shock.
The case is not much more expensive than some standard phone cases on the market, so if you’re looking for a little extra protection and extended phone life, this is a unique option.
