The folks over at WAKAWAKA are doing it right. They sell a great solar panel powered charger (hopefully! I’ll let you all know in the comments) for your phone or your tablet. Nice and simple. Their mission is the following :
WakaWaka (‘Shine Bright’ in Swahili) develops, manufactures and markets high-tech low-cost solar powered lamps and chargers that are indispensable products both in the developing world and in developed markets. Using the latest in patented solar technology, developed by our partner and market leader Intivation, the WakaWaka Light and WakaWaka Power are true lifesavers for those without electricity. Innovative and super efficient products for those that desire the finest in technology and design, while ‘enlightening’ people at the base of the pyramid, ending the deadly kerosene-dependence of millions.
And they had a drop dead gorgeous way to support after you purchased their product. You can see that below. More BOGO social impact brands could follow their lead.
