Hello, XS charging power current depends on the rated power and voltage of the charging device. In general, the XS charging power current can be calculated by the following formula:
Charging power current (A) = charging power (W)\/Charging voltage (V)
For example, if the charging power of XS is 20W and the charging voltage is 220V, the charging power current is:
Charging power current (A) = 20W \/ 220V = 0.909A
iPhone Xs charging current range: line 1A, wireless fast charge 2A.
