Apple lists exact gear needed for iPhone Duo fast charging

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

According to the company's support documentation, the phone can reach 50 percent battery in about 20 minutes via a wired connection. To hit that mark, users must use 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 at a price of $34. Alternatively, third-party chargers are acceptable if they are rated for 60W or more, use Adjustable Voltage Supply, and support USB Power Delivery 3.2.

Wireless charging operates at a slower pace, taking approximately 30 minutes to reach 50 percent. Apple states this speed requires a MagSafe Charger, which costs $30, or an adapter rated at 35W or higher. The guidance specifically mentions compatible adapters from Apple and Anker. Buyers seeking longer reach can purchase Apple's official 2-meter USB-C cable, which is currently available at a discount.

9to5Mac reported that third-party options often offer better value than first-party accessories. The outlet identified Anker's 100W charging brick as a top choice because it supports iPhones as well as power-hungry Macs and iPads. The writer noted that Apple's 40W adapter remains a reasonable purchase for customers who prefer a first-party solution.

Apple's documentation clarifies that fast charging is supported over both wired and wireless connections, but the headline speeds depend on pairing the phone with the correct accessories.
