Upgrading from the iPhone 17? Will your charger still do?
Almost certainly. The iPhone 17 range charges at up to 30W and the iPhone 18 range at up to 30W, so a charger that ran your iPhone 17 at full speed runs the iPhone 18 at full speed too. It's worth replacing only if it's under 30W, or USB-A rather than USB-C.

iPhone 18 charger questions
What wattage charger does the iPhone 18 need?
The iPhone 18 takes up to 27W, the iPhone 18 Pro takes up to 30W and the iPhone 18 Pro Max takes up to 30W. A USB-C Power Delivery charger of 30W or more charges all of them at full speed.
How long does the iPhone 18 take to charge?
With the SMARTGEAR 45W USB-C Super Fast Charger 3 Port GaN Wall Charger, the iPhone 18 charges from empty to full in about 49 minutes, the iPhone 18 Pro in about 45 and the iPhone 18 Pro Max in about 57. Phones and tablets slow down near the top to protect the battery, so the first half is much quicker than the last.
Is a 65W or 100W charger safe for the iPhone 18?
Yes. A USB-C Power Delivery charger only supplies what the device asks for, so the iPhone 18 takes up to 30W from a bigger charger and no more. The spare power can charge a second device from another port at the same time.
Do I need a special cable for the iPhone 18?
No. Any USB-C to USB-C cable rated for 3A (60W) carries the iPhone 18's full 30W. If you need one, the SMARTGEAR 100W USB-C Cable 2m is £8.99.
Are the iPhone 18 charging figures confirmed?
Not yet. Apple hasn't published charging specifications for the iPhone 18 range yet, so these figures are carried over from the previous models. We'll update this page when the official figures are out.
