USB Solar Charger with dual power back-up solution

Most USB gadgets are purely meant for fun and hardly any of them serve any purpose. The USB Solar Charger from Japan’s Thanko happens to be such a gadget, but with a difference. This is a Solar Charger with solar panels at its back to charge a variety of devices, mostly mobile phones. And incase the sun decides to play hide and seek, you can charge the device by plugging it into the USB port you laptop and charge the devices. Now that’s some smart thinking I must say! This smart solar charger is available at $21 here.
