YellowJacket: $85 ($125 retail)
The thought has crossed has my mind that if a dangerous situation presented itself, it would be great if my iPhone could help me out of it. Not just to call or text someone for assistance, but actually defend me from harm. So far, all I can do now is throw it at a perpetrator and maybe startle him.
The Yellow Jacket iPhone case may be the solution. It works like a stun gun and was delevoped by Seth Froom, who was robbed at gunpoint in his home. Froom was traumatized after the event and wanted to find a way to protect himself in the future with a device that was nearby and handy.
The case can zap an attacker with 650,000 volts of electricity, strong enough to bring down a full grown man, according to Froom. It has a built-in battery that can give an iPhone an extra 20 hours of battery life between charges. A safety switch on the case keeps the taser from taking its owner down accidentally, but when it does need to be used, it’s deployable with one hand.
