You can charge the empty battery of your Apple iPhone in no time with a Power Delivery fast charger with Lightning cable. All iPhone models from the iPhone 8 support fast charging. You can charge your device back up to 50% in half an hour. Without a fast charger, half an hour will only get you around 30%. You need a charger with at least 18 or 20W. More power is also fine. In that case, your device won't charge any faster, but it's not harmful for your battery either. All of these chargers include a cable. Choose a sturdy nylon cable if you want the cable to last a long time. With an extra long cable, you have more freedom of movement while you charge.
