Bike lights are expensive. Mine advertised itself as waterproof to 50 meters (for deep sea biking?) and used a magnetic power switch to keep itself hermetically sealed. This promptly broke and rather that shell out another $20 for a new one I decided to bolt on a push button switch I had. I also have the habit of leaving the light on and draining the battery so I decided to use the opportunity to upgrade my bike to solar power.
I’ll admit it is a bit of overkill since the only power needs were my front and rear lights. With all this effort I decided to add on a USB port to charge my phone since I use google maps a lot during longer rides.
Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We’ve spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we’re really pleased with what we ended up with.
