The iPhone Duo uses MagSafe, USB-C and Apple’s usual accessories, so most of what you own should just work. Not quite. It’s a 254 g foldable that’s only 117.8 mm tall when folded, with a folding screen that can’t take glass and a hinge that becomes an outer edge.
Some accessories made for regular iPhones overhang it, some aren’t safe on it, and some are simply slower than the phone can go. This is the complete kit, what fits a foldable, and what to skip.
- A case that covers the hinge (from $39.95). Find yours.
- Outer screen protection: front glass in the case, or a 3-pack protector ($24.95).
- A flexible inner film, never glass: the privacy set covers both screens ($24.95).
- A charger: a 25W MagSafe or Qi2 charger for speed, or a multi-device station for your desk.
- Optional: a car mount, a wallet sized for the Duo, a stylus.

| Method | Speed on the Duo | Best for |
|---|---|---|
| USB-C cable + 60W+ adapter | About 50% in 20 min (Apple) | Quick top-ups |
| Apple MagSafe Charger + 35W+ adapter | Up to 25W; about 50% in 30 min (Apple) | Fast wireless |

| Our 3-in-1 foldable station | Up to 10W | Overnight and travel: phone, watch, earbuds |
Honest take: our stations are about convenience, three to five devices on one compact, foldable charger, not top speed. If you want the Duo’s full 25W wirelessly, use an Apple MagSafe or Qi2 25W charger. If you want everything charged overnight from one plug, a station is the better buy.

Frequently asked questions
What accessories do I need for the iPhone Duo?
A case that covers the hinge, protection for the 5.4-inch outer screen (front glass in the case or a separate protector), and optionally a flexible film for the inner screen. Add a charger, a car mount, a wallet or a stylus depending on how you use it.
Do old iPhone accessories work with the iPhone Duo?
Most chargers and USB-C cables do. Magnetic accessories attach, but wallets and power banks designed for taller iPhones can overhang the 117.8 mm folded Duo, and cases and screen protectors must be made for the Duo.
What is the fastest charger for the iPhone Duo?
A USB-C cable with a 60W or higher adapter: about 50% in 20 minutes, according to Apple. Wirelessly, an Apple MagSafe Charger with a 35W adapter or a Qi2 25W charger, up to 25W.
Can I use a car mount with the iPhone Duo?
Yes, with the phone folded. Magnetic mounts need a magnetic case and a strong hold for the 254 g phone; gripping vent mounts work with any case.
Can I put a screen protector on the iPhone Duo?
Yes. On the outer screen, glass or film. On the inner folding screen, only a flexible film such as hydrogel, on top of Apple’s factory cover layer. Never glass.
Does the iPhone Duo come with a charger?
Apple hasn’t included power adapters with recent iPhones, so plan on using an existing USB-C adapter or buying one. For the fastest wired charging, Apple says to use a 60W or higher adapter.
Which MagSafe accessories don’t fit the iPhone Duo?
Accessories sized for taller iPhones, especially wallets and larger power banks, can overhang the short folded Duo. Apple’s own MagSafe Wallet was seen overhanging it at launch.
