Why make yet another standard instead of expanding the existing one? The newest USB-C standard allows for 240W at 48V. That should be enough for pretty much all mobile electronic devices. You could even charge an e-scooter at a reasonable rate. And at the same time, you could still charge your wireless headphones with the same charger because it's compatible. Doesn't get much better than that.
