> I am honestly very annoyed that my 2019 XPS 15 will refuse to negotiate anything higher than 65W over USB-C PD on a non-Dell charger. Their dock does 130W, yet every third party dock, brick, or monitor I use it refuses to exceed 65W. Until 2021, the official maximum power for USB-C PD was 100W (5A at 20V), and your notebook is older than that. Dell has a non-standard extension for higher power, which uses a higher current (above 6A) and the same voltage (20V); the newer standard instead keeps the same maximum current (5A) and allows for higher voltages. It makes sense that third-party devices implement neither Dell's non-standard extension nor the newer standard (which your laptop could not use anyway), and so are limited to 100W, or 60W if you're not using a 5A cable.
