In many of the locations we work, there is limited to no power - or at least a reliable source of power. In these situations, here are a few recommendations:
NOTE: these are just some that we have seen used before, always look for local solutions first as they will be the cheapest and ultimately best options.
- There are a number of solar panel providers that have small solutions for cell phones
- D-Light- in addition to larger manufactures and DIYers had solar power cell phone chargers.
- Nuru- has solar powered lights that can also charge mobile phones.
- SunTransfer lamps - seem to work better as they have much more powerful batters (sealed lead). Can sometimes be found locally
- Sun King - great low cost option that are both lamps and chargers.
- Alternatives to solar panels:
- BioLite - that chargers your phone and boils a pot of water a the same time. (NOTE: this was NOT designed for the developing world)
- Bicycle powered generator. Remember those old school bike lights that turned on when you pedaled your bike? Well, now it can power a light AND charge your cell phone at the same time. Scour the internet, as last time I checked Nokia, Nike, and a slew of Do It Yourself-ers all had websites with products and designs
Local Charging Stations:
- With the growing use of cell phones, it is more and more common for villages to find their own ways to charge cell phones, and turn it into a business. Many shops will have a battery or solar charger that they will offer to charge cell phones for a nominal fee. NOTE: beware that some of these shop owners like to take factory batteries out of phones and replace them with imitations, or mess with the software on the phone while its charging.
