If by in any reason you find yourself at off-grid location, weather in a tour in Africa or researching in an off grid village, you would like to know how you can recharge your phone. You might have some source of power around you; your car or motorcycle battery, bicycle dynamo, solar panel or dry cells on a shop nearby, but they are not suitable for your phone. In this workshop we will learn to build a simple charger that can convert any of these sources into suitable voltages to charge your cell phone.

This session is part of the GLOBAL INNOVATION GATHERING programme.
