As part of a recent marketing scheme to demonstrate the “recharging” properties of their product, Thai soy milk brand Vitamilk built a phone charging station that harnesses the power of batteries people have already thrown away.
Even though people assume there is nothing left, most discarded batteries still contain around four milliamps of unused energy. When you combine 1500 used batteries, this sliver of energy becomes enough to power 140 smartphones.
Organized in collaboration between BBDO and Proximity Thailand, the station built from donated batteries was placed in a shopping mall for two months to give passersby a chance to charge their phone.
