The Xperia XA1 Ultra supports MediaTek Pump Express Plus 2.0 charging technology which is the quick charging technology for devices with a MediaTek chipset.
We have two different chargers that supports this feature and the only difference between them is the cable that is included with the charger. You can still use the cable that was included together with your device and the UCH12 charger, or get the UCH12W charger that comes with a USB Type-C cable.
