iPhone Duo Fast Charging Specs Reveal 60 Watt Requirement

Apple has published specific hardware requirements to achieve maximum charging speeds on the iPhone Duo.

The company states that the phone can reach 50% battery in approximately 20 minutes when connected to a wired source. This speed relies on using the USB-C cable included in the box alongside a compatible power adapter. Apple lists its own 40W Dynamic Power Adapter with 60W Max as a first-party option, currently priced at $34.

For third-party solutions, Apple requires a charger rated for 60 watts or more. The documentation specifies that such adapters must utilize Adjustable Voltage Supply and support USB Power Delivery 3.2. These technical standards ensure the phone can draw the necessary power for the fastest wired charging experience.

Wireless charging offers a slower but still rapid alternative. Apple reports that the iPhone Duo reaches 50% in about 30 minutes wirelessly. Users need a MagSafe Charger, listed at $30, or an adapter rated at 35 watts or higher. Apple’s guidance identifies compatible devices from both Apple and Anker.

Anker’s 100W charging brick is cited as a value option that works with iPhones, Macs, and iPads. Apple’s 40W Dynamic Power Adapter remains a viable first-party choice at its reduced price. An official 2-meter USB-C cable is also available for users who need more reach than the included cable provides.
