The product design is meant to be iconic, but also compact – something you can travel with, that fits in the pocket of your jeans. Over two years, we worked directly with the engineers to develop the form factor as the technology was being refined. Its octagonal shape allows for more venting holes closer to the source of heat, to prevent overheating and keep the product cool to the touch. The multi-faceted geometry also draws the eye and separates Zolt from the bland rectangular standard chargers. To limit the size of the device while carrying it, we also allowed room for the prongs to fold in. With its cylindrical design, users can simply wrap their cords directly around its circumference when traveling; more importantly, when plugged in, the octagon can pivot 90 degrees to ensure the cords exit the most practical direction in often crowded sockets.
