Five years ago, USB-C brought the promise of one connector for everything. It combined power delivery, data transfer, and more into a small reversible port. While this helped make cables universal, USB-C has become a messy monster.
The original goals are hidden among all the new additions. Whether charging, transferring data, or using alternate functions, USB-C is overly confusing. It’s even worse than when I first wrote about it.
Charging with USB-C is complicated. Fast charging standards differ between brands. Some phones charge super fast with their own cables but very slow with others. While USB Power Delivery is common, speeds and wattages vary a lot. The new USB PD PPS standard caused more problems than it solved.
Telling data transfer speeds apart is a nightmare. Standards keep splitting into multiple versions like USB 3.0, 3.1, 3.2 and USB 4. Speeds range from 10 to 80 gigabits per second but it’s impossible to know what’s supported without research.
Using alternate functions over USB-C requires learning terms like “alternate modes.” You might expect HDMI or Ethernet on a laptop port but it may not have it. Features are also restricted to certain ports sometimes.
Cables add to the mess with both active and passive types needed. You must match the right cable to your devices and speeds. Adapters between USB-C and older ports cause issues too.
Manufacturers make things complicated to cut costs. Full USB-C support requires many extra internal parts. As a result, not all ports provide all functions.
Five years on, USB-C fails to deliver simplicity. Compatibility remains a guessing game of plug and pray. Constant standard updates only make understanding harder for users. Unfortunately, USB-C will likely remain a confusing mess going forward.
