Unlike solar panels that can only generate power while the sun’s shining, Aurea Technologies’ new Shine 2.0 portable wind turbine can potentially work all day long. That is, as long as the weather cooperates and provides an 8mph breeze needed to keep the turbine’s blades spinning.

Recharging your phone while enjoying the great outdoors can often be a hassle, but Aurea’s Shine 2.0 hopes to make it easier by harnessing a simple natural resource — the wind. Enter the Shine 2.0, the second iteration of the company’s portable wind turbine charger.

It can function all day long, and even at nights, as it just needs an eight miles per hour (12.7 km per hour) breeze to function, something which shouldn’t be much of a problem
