MagSafe Charger

The MagSafe Charger is a wireless charging device developed by Apple and released in October 2020 with the iPhone 12 series.

History
The charger resurrects Apple's MagSafe brand and is based on the wireless charging standard. It was announced in an Apple special event on October 13, 2020 in place of the previously-announced AirPower charging mat project, which was cancelled in March 2019. Apple also announced the MagSafe Duo Charger, a foldable version that can simultaneously charge a supported iPhone and Apple Watch, though it has not yet been released.

Description
The MagSafe Charger includes a proprietary magnetic coil that aligns and attaches the charger to devices that contain matching coils. This allows for charging at up to 15 s on iPhone 12 models when used with the officially supported 20-watt USB-C Power Adapter from Apple. However, it still functions at 13 watts when used with the older 18-watt adapter from the iPhone 11 series. On unsupported USB-C adapters, such as the 96-watt version for recent MacBook Pro models, the MagSafe Charger will only deliver up to 10 watts. Practical tests found that charging speed differences between 18-watt adapters for the iPhone 11 series and 20-watt adapters were negligible. The MagSafe Charger is also compatible with older iPhone and some Android models that support wireless charging, but only at a maximum rate of 5 watts.

Medical advisory
Users with s or s are advised to keep MagSafe devices at least 6 inches away, or 12 inches away while charging, to minimize risk of magnetic interference.
