FAQs
Is 20W enough for an iPhone?
For many iPhone charging situations, yes. The exact fastest supported result depends on the iPhone model, adapter, cable and charging conditions.
Is 40W twice as fast as 20W?
No. Charger wattage is not a direct promise of real-world charging speed because the phone controls its power intake and charging slows as the battery fills.
Which cable do I need?
iPhone 15 and newer use USB-C at the phone. iPhone 14 and earlier use Lightning. Match the cable to the phone-side connector.
