"Charge the battery

To charge iPhone, do any of the following:

• Connect iPhone to a power outlet using the charging cable (included) and an Apple USB power adapter (sold separately). See Power adapters for iPhone.
• 
• Place iPhone face up on MagSafe Charger or MagSafe Duo Charger (connected to Apple 20W USB-C power adapter or other compatible power adapter) or on a Qi-certified charger.
