iPhone Duo buyers may pay $249 for basic gear

Apple's iPhone Duo is now available, but several core features require extra purchases. The company's first foldable phone does not include a stylus, a fast charger, or a car mount in the box. Users must buy these items separately to access the full range of functions.

The total cost for the recommended add-ons reaches $249. This sum includes the Apple Pencil, a 40W power adapter, and a MagSafe car mount. The Apple Pencil (USB-C) is the only model that works with the Duo. It is priced at $69, down from its original cost of $79. Support for the pencil arrives next week in the iOS 27.2 update. This marks the first time an iPhone supports a stylus for writing and sketching on both screens.

Fast charging is another feature that requires a separate adapter. The iPhone Duo can charge to 50 percent in about 20 minutes, but only with a suitable power brick. The box includes a USB-C cable but no charger. Many owners may already have a 20W adapter, but that will not support the maximum speed. Apple sells a 40W Dynamic Power Adapter for $34. Anker offers a 100W USB-C charger with a five-foot cable for $29.

For navigation, the site suggests the ESR MagSafe Car Mount. It clips onto an air vent and holds the phone magnetically. The mount is currently priced at $19, down from $29. This setup allows the phone to display step-by-step directions while CarPlay runs on the car's main screen.

Protective cases are also available immediately. Third-party options include the SPIDERCASE Magnetic Case at $29 and the Spigen Ultra Hybrid Pro at $39. Apple sells its own iPhone Duo Folio with Kickstand for $129 and a standard iPhone Duo Case for $79.

The Duo also updates the StandBy mode. When the phone stands upright, it can display smart home controls even if it is not charging. Two specific views, Home Camera and Home Modular, allow users to check security cameras. Recommended compatible devices include the Aqara G100 2K camera at $39 and a eufy 4K camera at $69. The site also lists AirPods Pro 3 as a general recommendation, currently on sale for $199.

The iPhone Duo launch highlights a gap between the device's capabilities and its included hardware. Buyers must decide which add-ons are essential for their daily use. The accessory market for the new foldable is already active, with discounts available on several items.
