How fast can my iPhone, iPad or Mac charge?

The short version

A USB-C Power Delivery (USB PD) charger and your device agree how much power to send, so a higher-wattage charger is fine to use. Apple suggests using a Mac laptop’s charger to charge an iPad faster. What you need is enough wattage for the speed you want. The table shows what Apple quotes. Your device page has the exact wording for your model.

iPhone

iPhone	Wired fast charge (Apple’s figure)	Charger Apple quotes
iPhone 18 Pro, 18 Pro Max	Up to 50% in around 15 minutes	60W-capable adapter with Adjustable Voltage Supply (AVS), USB PD 3.1 or better, and a 60W-capable cable
iPhone Duo	Up to 50% in around 20 minutes	60W-capable adapter and cable
iPhone 17, 17 Pro, 17 Pro Max	Up to 50% in around 20 minutes	40W or higher
iPhone 17e, iPhone Air	Up to 50% in 30 minutes	20W or higher
iPhone 12 to iPhone 16 models	Up to 50% in around 30 minutes (Plus/Pro Max models may take a little longer)	20W or higher

Apple’s fast-charge article says a “comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)” works too. It also says iPhone 15 and later charge at no more than 7.5W from an old USB-A charger. Since iOS 18, your iPhone shows a Slow Charger message on the Lock Screen if a stronger charger would help.

Wirelessly: iPhone 16 and later can fast charge wirelessly with a MagSafe Charger and a 30W or higher adapter. iPhone 18 Pro reaches 50% in 30 minutes with a 35W or higher adapter. See MagSafe vs Qi2 vs Qi.

iPad

Apple’s minimum spec for an iPad charger is 15W with a USB-C output. Apple says a higher-wattage USB-C adapter, “such as the one that came with your Mac laptop”, charges iPad faster. iPad Pro (M5) can reach 50% in around 30 minutes with a 60W or higher adapter. That’s the only current iPad with a fast-charge figure on its spec page.

Mac laptops

Apple’s rule for USB-C Macs: you can charge with “any USB-C power adapter or display that supports USB Power Delivery”, even one rated lower than recommended. It will just be slower. For the best experience, Apple says use at least the wattage of the adapter it recommends for your Mac.

The 2026 models add a new line on Apple’s UK spec pages: “Minimum wattage required to charge the device”. That’s 20W for MacBook Neo, 30W for 13-inch MacBook Air (M5), 35W for the 15-inch, 60W or 70W for 14-inch MacBook Pro, and 140W for 16-inch MacBook Pro. In our finder, chargers below that figure show as Not compatible for those Macs.

Mac	Fast charge (Apple)	Notes
MacBook Air (2022 and later)	Up to 50% in around 30 minutes with 70W or higher	M5 models: power adapter sold separately in the UK
14-inch MacBook Pro (2021 and later)	Up to 50% in around 30 minutes with 96W or higher	Some configurations came with 67W or 70W
16-inch MacBook Pro	Up to 50% in around 30 minutes with 140W	Over USB-C, use Apple’s 240W cable (Nov 2023 model or later)
MacBook Neo	No fast-charge figure	Apple recommends its 20W USB-C Power Adapter

Two more Apple points worth knowing:

Plugging chargers into two ports doesn’t charge a Mac faster. It charges from one at a time.
A USB-C or Thunderbolt display that supplies power, such as Apple Studio Display, can charge your Mac instead of a separate charger.

Multi-port chargers

Apple says that on a charger with more than one port, such as its own 35W Dual USB-C Port Power Adapter, the “maximum power output may be reduced” when you charge two things at once. The same goes for hubs and car ports. For a MacBook, check what one port gives on its own, not just the total.
