USB-C Universal Charging

The convergence toward USB-C as a universal charging port is one of the most impactful design standards of the past decade. Having my phone, laptop, headphones, and portable speaker all charge from the same cable has reduced the tangle in my bag from 4 cables to 1. The connector is reversible, so you never plug it in upside down. Data transfer speeds are fast enough for external drives, and the power delivery can handle everything from a phone at 15 watts to a laptop at 100 watts. Developed collaboratively by competing companies and then adopted gradually until it reached a tipping point where holdouts looked stubborn rather than principled, the standard is a rare example of industry coordination that actually worked. The EU mandated USB-C for all devices starting in 2024, and that regulation accelerated a transition that market forces were already driving.
