This DIY Phone Charger is a solar-powered device that can be built in five minutes for just five dollars. If that's not enough to bowl you over, the design also includes a built-in stand and has been tested for compatibility with Apple and Android products.

Instructables user 'ASCAS' came up with a tutorial to help people power their cell phones with off-the-grid energy from the sun. If you're away from an outlet, this is the perfect way to top up on a sunny day.

All you need to create this device is a mini solar panel, a USB charger circuit and the charger cable for your phone. It is astonishing that this tutorial uses so few materials, hardly costs any money and in just four steps, you can create your very own sustainable phone charger.
