Your iPhone can be wirelessly charged quickly and securely with the MagSafe Charger. In order to optimize charging your iPhone at up to 15W of peak power supply for quicker wireless charging, the system dynamically responds to environmental factors.
The wattage of the power adapter and other system factors will affect the actual power delivered to the iPhone. The MagSafe Charger can supply up to 12W of peak power delivery to the iPhone 13 mini and iPhone 12 mini.
Before putting your iPhone on the MagSafe Charger, make sure it is connected to a power source. By doing so, MagSafe can confirm that it is secure to deliver maximum power.
If you accidentally put your iPhone on the MagSafe Charger before plugging it into a power source, just take it off, wait three seconds, and then put it back on to resume receiving the maximum amount of power.
