To show its Brazilian customers that they “don’t need to leave the sun for anything”—not even to charge their cellphones—skin care brand NIVEA created a ‘Solar Ad Charger’.
Made with a material that captures solar energy, the ad is capable of turning sun rays into power for cellphones.
To charge their devices, customers simply attach their cellphones to the ad with a USB power cable and leave the ad in sunlight to charge.
