Portable energy source with unique re-charge feature The item can be charged with the integral step treadle or by more alternate energy source such as solar panels wind turbines plus from mains electricty Can jumpstart car & marine engines 12V power via cigarette lighter socket The Free Charge Weza is a portable power supply putting out 12 Vdc through a standard cigarette lighter style plug. It puts out enough power to jump-start a car or boat but can also recharge most portable devices. This device shines in emergency situations such as when your car needs a jump start on a deserted road & uses a 7 Ah sealed lead acid battery. What is really cool however is the way that you can charge it
- You step on it More precisely you use the step treadle meaning that you step up & down on it for a short while to bring the battery back up to full. If that doesnt sound like much fun the Weza is designed to be charged with solar panels & small wind turbines Freeplay recommends a 30 watt rating. You can even recharge it from a wall outletbut thats cheating.
