iPhone Duo Charging: 60W adapters required for 20-minute speeds

Apple has published support documentation detailing the specific hardware required to achieve the fastest charging speeds on the iPhone Duo. The company states that the device can reach 50 percent battery in approximately 20 minutes using a wired connection. To hit that benchmark, users must pair the phone with the included USB-C cable and a compatible power adapter.

Apple lists its own 40W Dynamic Power Adapter with 60W Max as a suitable option, currently priced at $34. The documentation also allows for third-party adapters, provided they are rated for 60W or more. Those external chargers must utilize Adjustable Voltage Supply technology and support USB Power Delivery 3.2 to ensure compatibility.

Wireless charging offers a slower but still rapid option for the new device. Apple reports that the iPhone Duo can reach 50 percent battery in about 30 minutes when charging wirelessly. This speed requires a MagSafe Charger, which costs $30, or a third-party adapter rated at 35W or higher. The company identifies compatible hardware from Apple and Anker as suitable choices.

Third-party reviewers have noted that non-Apple chargers often provide better value for money. One recommended option is Anker's 100W charging brick, which supports not only iPhones but also high-power devices like Macs and iPads. The same reviewer suggested that Apple's 40W adapter remains a cost-effective choice for buyers who prefer first-party accessories.

Users seeking longer cables than the one included in the box can purchase Apple's official 2-meter USB-C cable. The device's charging specifications clarify the power requirements for both wired and wireless methods, giving consumers a clear list of necessary components to maximize their charging efficiency.
