The result is the world’s smartest all-purpose party starter. It stores food and drinks, sure. But it also touts a blender (“for vodkaritas,” Grepper offers), an LED lid light (“to see if you’re reaching for beer or Clamato juice”), a USB charger (“so nobody’s phone dies”), a Bluetooth speaker (for tunes) and big wheels designed to navigate many terrains (beach, parking lot). “I just want to make the coolest cooler out there,” says Grepper. Hence the name: Coolest Cooler.
