How to use MagSafe Duo Charger with your iPhone and Apple Watch
The MagSafe Duo Charger is designed to quickly and safely wirelessly charge your iPhone 12, iPhone 13, or iPhone 14 and your Apple Watch simultaneously. The system intelligently adapts to conditions to optimize charging your compatible iPhone at up to 14W of peak power delivery. The actual power delivered to the iPhone will vary depending on the wattage of the power adapter and system conditions. For iPhone 12 mini and iPhone 13 mini, the MagSafe Duo Charger delivers up to 12W of peak power delivery.
It’s important to plug into a power source before placing your iPhone on the MagSafe Duo Charger. This allows MagSafe to verify that it’s safe to deliver maximum power. If you happen to place your iPhone on the MagSafe Duo Charger before plugging into a power source, remove your iPhone from the MagSafe Duo Charger, wait three seconds, and then put it back on to resume maximum power delivery.
The MagSafe Duo Charger is designed to negotiate the maximum power up to 9 volt (V) and 3 amp (A) with a USB PD compatible power adapter. MagSafe will dynamically optimize power delivered to the iPhone. The power delivered to the iPhone at any moment will vary depending on various factors including temperature and system activity.
All power adapters have different ratings for the amount and rate of power delivery. The MagSafe Duo Charger requires the following ratings to deliver faster wireless charging:
- USB-C connector (USB-A is not supported)
- 9V/2.22A power adapter provides up to 11W of power
- 9V/3A and higher power adapter provides up to 14W of power
- iPhone 12 mini and iPhone 13 mini can get up to 12W for faster wireless charging with at least 9V/2.62A
- Higher wattage adapters at or above 9V/3A will also deliver a maximum of up to 14W peak power to your iPhone
To use both the iPhone and Watch charger at the same time, the MagSafe Duo Charger requires at least 15W (5V/3A or 9V/1.67A), but this will result in slower charging.
When Lightning accessories such as headphones are connected, charging is limited to 7.5W to comply with regulatory standards.
