The Powermonkey Expedition features 32:1 gearing which allows you to use a hand crank to produce power and 10 minutes of cranking gives you 1% charge on the Powermonkey Expedition’s internal battery. Not sure if you’re cranking at the right speed? The device has a simple LED that goes green when you’re up to snuff.
Don’t want to crank and have stiff wind? Or, driving to a destination? Attach the Powermonkey Expedition to the top of your vehicle to create your own wind while you drive around. Just pull out the silicon windcups and attach them. Want more? Pull out a solar panel and attach that, even while you are using wind power generation.
Near a stream? Flip it on its side and harness the power of gravity to spin the cups with water.
