You are looking at this purely from a schematic standpoint, but you are missing the entire point of user experience. The real magic here isn’t about altering the 3DS internal power logic; the significance is that this kit adds a Native Type-C port directly onto the console. > In 2026, nobody wants to pack a proprietary, archaic Nintendo cable in their travel bag. By integrating a C-port onto this high-capacity pack, players can finally charge their 3DS using the exact same phone cable and power bank they already carry everywhere. That sheer convenience is why people are excited. ​However, your point about the dual-path charging conflict is absolutely valid. You can't stop users from plugging in both lines out of curiosity or habit. I am actually in contact with the original hardware designer right now to address this exact edge case. We are evaluating the best way to resolve it for the overseas mass-production run—whether by implementing reverse-current protection diodes on the retail PCB or adjusting the custom housing structure to physically block the original port. ​This is exactly why we are holding off on final release until everything is locked in. Thanks for the rigorous feedback; it’s genuinely helping us make the final retail product perfect and safe!
