Can the 20wpd fast charger charge the ipad7 generation? Agreed.
Can be charged, but does not support fast charging, 12W power charging, 20W charger can output 12W, but ordinary charging is not fast charging, charging cable conversion cable connected to the charger jack and flat jack can be.
Use the original charger set to charge the iPad2020, the power is 5.12V 2.53A 12.99W, at this time in the Apple2.4A charging state, and does not trigger the 9V PD fast charge.
