Yes, you can safely plug your iPhone into a 220V outlet using a simple plug adapter, as the iPhone's power brick is "dual-voltage." If you look at the tiny print on your Apple power adapter, you will see it is rated for "100-240V, 50-60Hz." This means the internal circuitry is designed to automatically handle the higher voltage found in Europe, Asia, and the UK without needing a heavy voltage converter or transformer. All you need is a physical "travel adapter" that changes the shape of your home prongs to fit the local wall socket (such as the Type C "Europlug" or the Type G "UK plug"). This applies to all iPhone models in 2026, as well as iPads and MacBooks. However, be cautious with other household electronics like hair dryers or curling irons; if they are not labeled as dual-voltage, plugging them into a 220V outlet will likely cause them to smoke or catch fire. For your iPhone, simply "plug and play" with the correct adapter, and your device will charge just as quickly as it does at home.
