USB-C charging accessories may work with both, but cases are model-specific. Apple’s first foldable, iPhone Duo, was announced on September 9, 2026, with retail availability scheduled to begin October 23, 2026; it is not yet on sale as of October 4, 2026. Duo supports MagSafe and Qi2 25W charging. Samsung’s Galaxy Z Fold7 can use magnetic accessories with a compatible case that has an integrated magnetic ring, but that does not guarantee every MagSafe accessory will fit or charge at the same speed.
Which accessories can you share?
The clearest shared category is USB-C charging equipment. Other accessories depend on the phone’s shape, case, charging standard, or software support. Compatibility is about more than whether a plug or magnet attaches: confirm the exact device listing and intended function before buying.

| Accessory | iPhone Duo | Galaxy Z Fold7 | What to check |
|---|---|---|---|
| USB-C cable and wall charger | USB-C charging. Apple says wired fast charging uses a USB Power Delivery adapter and a cable rated for 60W or higher. | USB Type-C. Samsung’s claim of up to 50% charge in around 30 minutes uses a 25W adapter and 3A USB-C cable. | A USB-C PD charger is a practical shared option, but the phones have different stated fast-charge setups and will not necessarily charge at the same rate. Check adapter output and cable rating. Apple; Samsung |
| Protective case or folio | Apple describes its Duo Case as a two-part design wrapping both sides of iPhone Duo, and also lists a Duo Folio. | Samsung lists its Thin Fit Case for Galaxy Z Fold7. | Buy for the exact model. Neither manufacturer claims cross-fit between these devices. Apple; Samsung |
| Magnetic grip, mount, wallet, or charger | Apple says Duo and its cases align with MagSafe and Qi2 25W accessories. | The Fold7 Thin Fit Case has an integrated magnetic ring for magnetic accessories. | Use an accessory explicitly listed for the phone or its case. Check secure attachment when the phone is open and closed, plus camera and hinge clearance. A magnetic ring does not establish universal MagSafe fit or charging speed. Apple; Samsung |
| Qi wireless charger | Apple says Duo supports Qi-certified chargers; Duo cases support Qi2 25W. | Samsung lists WPC Qi wireless charging support. | A Qi charger may charge either phone without magnetic alignment. Do not assume that Fold7 will snap to a MagSafe charger or reach Duo’s stated Qi2 25W capability. Apple; Samsung |
| Stylus | Apple announced Apple Pencil with USB-C support for later in 2026; it is not available for Duo as of October 4, 2026. | Samsung’s specification sheet says S Pen support: “No.” | These are not interchangeable stylus systems. Check Apple’s availability before buying a Pencil for Duo. Apple; Samsung |
| Stand | Apple describes Duo as usable propped on a surface for hands-free calls. | Fit depends on the stand, phone dimensions, case, and hinge configuration. | For a universal stand, check supported width, load, and opening range. Screen size alone does not establish fit. Apple; Samsung |
Can you use MagSafe on a Samsung Galaxy Z Fold7?
Not as a built-in, manufacturer-confirmed MagSafe feature. Samsung’s Fold7 Thin Fit Case includes an integrated magnetic ring intended for magnetic accessories, which provides a route to attach compatible accessories when that case is installed. The ring does not prove that every MagSafe-branded charger, wallet, grip, or mount will align correctly, stay secure, or deliver its advertised charging rate on Fold7. Check the accessory maker’s specific compatibility information.
Wireless charging and magnetic attachment are separate questions. Samsung lists WPC Qi wireless charging for Fold7, while Apple describes MagSafe and Qi2 25W alignment for Duo and its cases. A Qi charger can charge without magnets; that alone does not mean a phone will magnetically attach to a charger.

Do iPhone Duo and Galaxy Z Fold7 cases fit each other?
No cross-fit is established by either manufacturer, so choose a case made for the exact model. Apple’s Duo Case is a two-part protective design that wraps both sides of Duo; Samsung identifies its Thin Fit Case as a Fold7 case. Similar foldable layouts do not ensure matching dimensions, hinge coverage, camera openings, or button placement.

- Confirm the exact device and case. Look for “iPhone Duo” or “Galaxy Z Fold7” on the accessory listing, not just “foldable phone” or a broad brand name.
- Match the function. For charging, check wired USB-C PD, Qi, or Qi2 support as applicable. For a magnetic item, confirm both attachment and charging compatibility if it is a charger.
- Check the folded and open fit. Review width, folded thickness, camera clearance, and hinge clearance, and verify whether the item can be used in both configurations.
- Verify the rated setup. For wired fast charging, make sure the cable and adapter meet the phone’s stated requirements; a shared USB-C connector does not guarantee equal charging speed.
The form factors help explain why fit needs checking: Apple gives Duo a 7.6-inch inner display and 5.4-inch outer display, while Samsung lists Fold7 at 8.0 inches open and 6.5 inches on the cover. These display measurements describe the screens, not accessory dimensions or compatibility. Apple; Samsung
