The three rules
- Effective charging = the lowest of monitor PD watts, cable rating and device maximum.
- Cables: an ordinary USB-C cable carries up to 60W (3A). Above 60W you need a 5A cable with an e-marker chip (100W); above 100W, a 240W (EPR) cable.
- Below the recommended wattage, a laptop charges when idle and can drain under load. A 65W monitor charges a 14-inch MacBook Pro, just not at full speed.
