Solar Chargers for Small Electronics
As with solar battery chargers, there are a number of solar chargers available for use with cell phones, mp3 players and other electronic devices. Some consist of solar cells connected to a universal charger that can power a number of devices. Others, such as solar cell phone carrying cases, are made to power specific devices.
When choosing a charger for a small device, you will want to consider both portability and the watts provided by the charger. Chargers with a low wattage may take too long to charge your device to be practical. And, if you are planning on charging your device on the go, you will need to ensure that the charger you choose is small enough to be convenient to take along. More powerful chargers will cost more, but will pay off if you want to be able to charge devices more quickly.
One option is to choose a charger that fits easily in the back window of your car, so that you can charge your device while driving, or while parked in a sunny place. Another is to pick a solar charger with an internal battery. You place the charger in a sunny spot during daylight hours to charge the battery. Then, at your convenience, you plug in your device to be recharged.
