Running out of power with your smartphone quickly disconnects you from your life, which is where the Voltmaker can come in handy for quickly charging up without the need for a traditional electrical outlet.
Using kinetic energy, the Voltmaker powers when the built-in wing is whipped to create a charge; from here, the volts can be transferred to an iPhone, Android or even tablet device for quickly powering back on. A flashlight is built into the opposite end of the Voltmaker, which makes it a great, all-in-one device for emergencies.
While other kinetic chargers on the market require cranking or other monotonous motions that can cramp up your hands, the Voltmaker uses a sophisticated motion that won't cause fatigue too fast and might actually help give your arm a work-out.
