According to a clip uploaded by ChargerLab on YouTube, iPhone 13 Pro Max could sustain a charging power of up to 27 watts. This capability is made impressive when the device is connected to the USB Type-C power adapter given that it exceeds 30 watts or more.
Compared to the previous iPhone 12 Pro Max, the charging speed of the predecessor phone only peaked at 21 to 21 watts using the same adapter setup.
