Shining a new light on USB chargers.

The standard method for recharging USB devices is to connect them to a computer or adapter. These objects get their own power from the local power grid. So it’s just a little extra cost on the electric bill. And a little more pollution is generated at the power plant. But here’s a way to cut out both of these problems; a solar powered usb charger. It provides energy that’s cost-free and pollution-free. You can use your computer for other things while the solar powered usb charger takes care of recharging the USB devices. Just place it in direct sunlight. Its solar cell produces clean, direct-current electricity to recharge the batteries.
