GaN Charger Lets You Swap Plugs, Stack Blocks, Pick Your Wattage - Yanko Design

"GaN chargers have gotten smaller and more efficient over the years, but they still look like anonymous black or white bricks. Most people toss them in a bag and forget about them, and if you travel frequently, you end up carrying a separate adapter for different plug types. It's functional but incredibly boring, and the whole category feels like it stopped trying once the engineers got the size and wattage right."

"Bang Design's LEGO-inspired GaN charger is an intern project that tries to make chargers fun and modular instead. The concept treats the charger as a colorful block system, with different cubes for different wattages and swappable plug modules for different countries. It's patent-pending but still just a concept, though it looks polished enough that you could imagine buying a set off a shelf and arranging them on your desk like tiny toys."

"One green cube houses a sliding plug carriage with metal prongs that can be removed and replaced with different pin standards for US, Indian, or European outlets. A rectangular recess on one face holds the carriage, and gold contacts inside suggest a cartridge-style electrical connection. The plug becomes just another swappable piece of the system rather than something permanently wired to the charger, which is the whole point."

GaN chargers shrank and improved efficiency, yet remained visually generic and often require separate travel adapters. Bang Design proposes a LEGO-inspired modular charger system composed of colorful cube and cuboid modules representing different wattages and port configurations. Plug modules slide into a carriage with removable prongs and gold contacts, allowing easy replacement for US, Indian, or European pin standards. Color-coding differentiates 65 W, 30 W, 120 W, and mixed-port variants. The design emphasizes playful aesthetics, cartridge-style electrical connections, and user-selectable blocks for device-specific charging and convenient travel adaptability.
