9to5Mac Recommends Five Accessories for Upcoming iPhone Duo

The report says Apple Pencil support will arrive on iPhone Duo later this year through a software update. When it does, it will require an Apple Pencil (USB-C); no other Pencil models are compatible. The stylus will work on both the outer and inner displays, and the foldable's design was inspired by the proportions of a standard A-series paper notebook, according to the article. It lists Apple Pencil (USB-C) at $69, down from $79.

For charging, 9to5Mac says iPhone Duo supports fast charging that can reach up to 50 percent in 20 minutes, but the fastest speeds require the right power adapter. It recommends Apple's 40W Dynamic Power Adapter with 60W Max, now $34, down from $39, and names Anker's 100W power brick as a strong third-party alternative at $29 with a 5-foot cable. Like other iPhone models, the article notes, iPhone Duo does not include a power adapter in the box, only a USB-C cable.

The list also recommends ESR's MagSafe Car Mount at $19, down from $29, for use on the go. The article says the mount provides a secure magnetic attachment and can clip to an A/C vent so the phone remains visible and easy to reach. It describes using the mount alongside CarPlay so Apple Maps navigation appears on the vehicle's CarPlay screen while the iPhone shows full step-by-step directions, a setup the article expects to improve with iPhone Duo's larger screen.

On protection, 9to5Mac notes that Apple is not yet selling its new $129 iPhone Duo Folio with Kickstand. It says third-party cases are already available, and buying one can prepare users for October 23 while offering a preview of the iPhone Duo's size and shape before committing $1,999 or more. The article highlights SPIDERCASE's Magnetic Case with a built-in stand and screen protector for $39 and Spigen's Ultra Hybrid Pro clear MagSafe-compatible case for $34, though it states that it has not tested these cases.

The final recommendation concerns home cameras for iPhone Duo's StandBy mode. According to the article, iPhone Duo will include a powerful upgrade to the current iPhone StandBy feature, allowing it to display a variety of StandBy views even when it is not charging. Those options include Home Camera and Home Modular views, both of which provide access to smart home accessories. The Home Camera view is described as especially useful for keeping track of security cameras at a glance. The article recommends Aqara's G100 2K security camera at $39 and eufy's 4K security camera at $59 as HomeKit-compatible options.

Editor's Summary 9to5Mac's Sept. 28, 2026 article recommends five accessory types for the upcoming iPhone Duo, led by Apple Pencil support that requires the USB-C model and works on both displays. It also covers fast-charging adapters, a MagSafe car mount, third-party cases and HomeKit cameras for the device's StandBy mode. The recommendations appear ahead of an October 23 reference date and a $1,999-or-more price threshold cited in the article.
