Joule Box Portable Charge StationThe Joule Box
Mike Strizki's latest renewable energy creation, The Joule Box, is a portable charge station capable of providing continuous off-grid electricity. Replace your old gasoline generator and never buy another gallon of fuel! The Joule Box is now available for sale and features tracking solar panels with GPS technology and battery back-up power storage. Optional wind turbine and onboard hydrogen gas generation upgrades can provide extra energy production and storage capacity. The Joule Box can even back-feed the electrical utility grid, earning you money when your own energy demand is low. The unit is ideal for off-grid homesteading, emergency preparedness and disaster prepping, or simply putting your mind at ease knowing you will always have back-up energy!
