The U.S. Army is testing one at its South Pole station. Greenpeace International has ordered some for use in India. A dive boat operator is using one to run compressors and lights in the Caribbean.
A solar power unit that can be carried in a backpack was created by a Portland, Oregon, inventor and released just three months ago. It is already making its way around the world.
The Solar Power Pack contains a folding monocrystalline solar panel, battery, controller, plugs, cords and light. It weighs only 24 pounds but provides users with 120 watt-hours of power a day.
The unit can power AC and DC electronics up to 300 watts. It can be used in recreational vehicles as well as for field research, emergency home power, disaster relief and international aid.
After charging for six hours with the unit’s solar photovoltaic panel, the Solar Power Pack can run a laptop computer for three hours or its own high-efficiency light for 14 hours.
