Overview

• Apple has submitted two MagSafe charger models, A3503 and A3502, to Taiwan’s NCC certification site featuring a white puck design and braided USB-C cables in 1 m and 2 m lengths.
• The chargers support the forthcoming Qi2.2 wireless charging standard, which is expected to boost maximum power from 15 W to as much as 50 W once officially certified.
• Certification documents list the pucks’ output at 15 V × 3 A for a peak 45 W charge when paired with a compatible USB-C power adapter.
• Qi2.2 introduces improved magnetic alignment and charging efficiency to ensure quick device snap-on and reduced power loss or heat.
• Testing records indicate the new MagSafe pucks are backward compatible with iPhone models back to the 11, increasing the likelihood that the iPhone 17 series may adopt the upgraded standard.
