STACK is a modular surge protector, designed by serial inventor Michael Ma. It snaps together (hence the name) to charge and protect exactly the number—and type—of devices you have. Simply add or remove modules depending on how many devices you need to charge. You start with a power base that has three or more outlet modules and an additional end connector piece. Add different modules to it—from circuit breakers to USB chargers and even Ethernet adapters. Each module type is color-coded to make it easy to identify. They all have enough surface area so you can fill up the whole strip and your devices won’t have to compete for space. Watch the video after the break for more details. Available for purchase here.
