A 65W GaN charger that can feed a laptop and a phone is worth the drawer space. A no-name 20W cube that runs hot is not a bargain.
Match the protocol. Some phones want PPS. Some laptops want USB-C PD. The wrong combo just charges slowly and warms up.
Cables fail first. If a lead is floppy at the plug or gets warm, retire it. We stock replacements that actually carry the advertised watts.
