Apple outlines specific hardware requirements for iPhone Duo fast charging

Apple published support documentation specifying that the iPhone Duo reaches 50 percent battery in roughly 20 minutes when charging via a wired connection. The company states this speed requires the USB-C cable included in the box paired with a compatible power adapter. Apple lists its own 40W Dynamic Power Adapter with 60W Max as one option, noting a price of $34. Buyers may also select third-party adapters rated for 60W or more. Apple's guidance requires these external chargers to use Adjustable Voltage Supply and support USB Power Delivery 3.2.

Wireless charging operates at a slower pace, with the phone reaching 50 percent in about 30 minutes. Apple specifies that users need a MagSafe Charger, listed at $30, or an adapter rated at 35W or higher. The documentation points to compatible power adapters from Apple and Anker for this setup.

The 9to5Mac report notes that third-party chargers often offer better value than Apple's own hardware. The outlet identifies Anker's 100W charging brick as a top pick, stating it works well with iPhones as well as Macs and iPads. The writer adds that Apple's 40W Dynamic Power Adapter remains a good deal for those preferring a first-party option.

Users seeking more reach than the standard cable provides can purchase Apple's official 2-meter USB-C cable. The article notes this item is available at a discount. Apple's documentation closes by detailing these specific accessory requirements for both wired and wireless fast charging.
