My older Xiaomi MiAir 12.5 notebook could charge over usb-c but only using a charger supplying 20v @ 2.25a or higher. So I think this hit or miss experience with PD chargers could be down to various notebooks using different power delivery-states.
Most lower powered chargers only supply up to 12v @ 2a (24w), while laptops sometimes expect to be charged at 15 or 20v, with at least 2a (30 or 40w). So any random usb-c PD charger still might not be compatible with this notebook, sadly.
Often sellers quote the different PD profiles the charger can supply or show a picture of the charger where the supported PD profiles are shown.
Here an example from an Amazon page about an Aukey charger:
Model: PA-D5.
Ingang: AC 100-240 V, 50/60 Hz.
USB-C-uitgang 1 (18W Power Delivery): 5 V 3 A, 9 V 2 A, 12 V 1,5 A.
USB-C-uitgang 2 (60W Power Delivery): 5V 3A, 9V 3A, 12V 3A, 15V 3A, 20V 3A.
Maximaal uitgangsvermogen: 63 W.
Afmetingen: 67 x 64 x 29 mm.
Gewicht: 148 g.
Does the supplied charger or manual give soms hints about what the required power delivery profiles could be needed?
