Americans purchase nearly 3 billion dry-cell batteries every year to power radios, toys, cellular phones, watches, laptop computers, and portable power tools. Most of these batteries consequentially end up in the trash. Buying rechargeable batteries is a good start -- but why not go further? Harvest the power of the sun with a solar powered battery charger! Keep your favorite electronic devices humming, while minimizing their impact on the environment. This high-power solar battery charger charges two batteries at once of the same type and size (D, C, AA, AAA). It puts out about 150mah and about 5 volts. All of the other solar powered battery chargers we tested were unsuitable because their voltage was too low.
