Charger specs are opaque
Manufacturers list total wattage but rarely break down what each
port actually delivers, or which protocols are supported. A 100W
charger might only deliver 10W to your phone if the protocols
don't match. Most people don't find out until they're staring at
a slow-charging notification.
Protocols are a nightmare
USB PD, PPS, Quick Charge, SuperVOOC — they don't all play nicely
together. Different voltage windows, different current limits,
different handshake sequences. Matching a device to a charger
requires reading documentation that most people don't know exists,
if it exists at all.
