What to buy: any reputable USB-C PD charger of 20W or more. A $20 GaN brick from Anker or Ugreen charges the Duo at full speed. MagSafe works for desk/nightstand top-ups, and a magnetic power bank is the smart pairing for heavy unfolded days.
The basics
| Wired | 20W over USB-C. Charger not included in the box. |
|---|---|
| MagSafe | Supported — including through Apple's own Folio case, which passes MagSafe on both sides of its kickstand. |
| Battery | 4,883 mAh dual-cell — see battery expectations |
What to pair it with
- A compact GaN charger (20–30W): cheapest full-speed wired option. 30W headroom doesn't charge faster but handles the Duo plus a cable for something else.
- A MagSafe stand or pad: the Duo's StandBy poses make a charging stand genuinely useful — desk clock by day, bedside clock at night.
- A magnetic power bank: the inner display is a battery eater. A 5,000–10,000 mAh magnetic pack covers the gap without a cable.
- Watch for: third-party Duo cases without MagSafe magnets — a case that blocks magnetic charging is a real regression on this phone.

FAQ
Is 20W slow?
For wired charging in 2026, yes — it's Apple's conservative choice, likely thermal-related given the dual-cell foldable layout. Expect roughly half a charge in ~30 minutes, like recent iPhones.
Does MagSafe work through cases?
Through Apple's Folio, yes — it's designed for it. For third-party cases, look for "MagSafe compatible" with built-in magnet rings; a case without them weakens or kills magnetic charging.
