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.

Every module is a perfect cube or tall cuboid with sharp edges and flat faces that instantly read as building blocks. The 65 W version has a red top half, white bottom half, and large “65 W” printed on one side in light gray type. A subtle asterisk mark on the top hints at a LEGO stud without copying it directly. The rest of the family uses green, blue, yellow, and pastel beige blocks with the same bold geometry.
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.
Different wattage blocks have different port configurations. The blue 30 W cube has one USB-C port, the yellow 120 W block has three outputs, and the beige version mixes USB-A and USB-C. Users could pick the block that matches their device or build a small family that shares the same plug module. The big printed wattage numbers make it easy to grab the right cube without squinting at tiny labels.
One cube plugs into the wall while the other blocks sit on the desk like small sculptures. The chargers stop being clutter to hide and start looking like a collection you might actually enjoy arranging. The LEGO reference makes the whole setup feel approachable and almost toy-like, especially compared to the usual tangle of anonymous black bricks and bulky travel adapters that most people carry around.
Turning this into a real product would mean solving serious issues around safety certifications, heat dissipation, and mechanical durability for those swappable parts. But the concept is still valuable because it shows how even a commodity accessory can carry personality and systems thinking. The LEGO-inspired GaN charger hints at a future where chargers are not just smaller and faster, but also more playful and easier to live with.
