Apple requires 60W adapters for peak iPhone Duo speed

Apple has published the hardware requirements for its new iPhone Duo, specifying that users need high-power adapters to achieve the device's maximum charging speeds. The company's support documentation outlines the exact accessories required for both wired and wireless connections.

For the fastest wired charging, Apple states the iPhone Duo can reach 50 percent battery in approximately 20 minutes. To hit that benchmark, customers 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 as a first-party option, priced at $34.

The company also allows third-party chargers. Apple's guidance specifies that any external adapter must be rated for 60W or more. It must also utilize Adjustable Voltage Supply and support USB Power Delivery 3.2 standards.

Wireless charging operates at a slower pace. Apple reports the device reaches 50 percent in about 30 minutes when connected to a MagSafe Charger or an adapter rated at 35W or higher. The company points users toward compatible products from Apple and Anker. The MagSafe Charger is listed at $30.

Third-party options often offer better value for money. Anker's 100W charging brick is cited as a strong alternative that works with iPhones, Macs, and iPads. Apple also sells an official 2-meter USB-C cable for users who need more length than the included cord provides.

The documentation leaves little room for interpretation on the power requirements. Buyers who want the advertised 20-minute recharge window must purchase hardware that meets the 60W threshold.
