There is perhaps no greater scourge of 21st-century human existence than the dead cell-phone battery. To ease the pain, Doug Baldasare WG12 and his company, ChargeItSpot, have created charging stations for retailers to set up in their stores. Unlike traditional hookups, these stations ask users to fill out a quick survey about their shopping experience. It’s a win-win: Patrons get their phones charged for free, while stores get extra foot traffic and deeper insight into their products, marketing, and customer experience. With more than 140 retailers already in the portfolio, ChargeItSpot has powered up more than two million phones to date.
