Apple, in a support document detailing best practices for its MagSafe Duo charger, said users will not be able to simultaneously charge an iPhone 12 and an Apple Watch with the company’s 29W power adapter.
MagSafe is a new feature on all iPhone 12 models that allows magnetic accessories to be attached to the back of devices, including Apple’s MagSafe charger for more precise wireless charging.
According to the support document, Apple’s older 29W USB-C power adapter is not compatible with MagSafe Duo, presumably because that adapter does not support the required 5V / 3A or 9V / 1.67A power ratings.
Because of this, when the MagSafe Duo is connected to the 29W adapter, it can only charge one iPhone or Apple Watch, rather than both devices simultaneously.
Earlier, Apple indicated that its new MagSafe charger will be limited to a maximum power delivery of 12W when used with the iPhone 12 mini, compared to 15W for other iPhone 12 models.
When Lightning accessories like EarPods are connected to any iPhone 12 model, the MagSafe charger is limited to a 7.5W charge to meet regulatory standards.
Apple said you have to connect the MagSafe charger to the power supply and then put the iPhone 12.
This allows the charger to verify that it is safe to deliver maximum power.
