The iPhone 17 is the first standard iPhone that can use a 40W charger, and Apple ships it with a cable and nothing else. So the question isn't just which plug fits. It's how many watts your brick needs to deliver what Apple advertises, and whether the charger you already own is good enough.
The iPhone 17 uses a USB-C charger that supports USB Power Delivery (USB-PD), with a USB-C to USB-C cable. Any USB-C PD charger will work. For Apple's fastest speed, 50% in about 20 minutes, use a 40W or higher adapter; that applies to the iPhone 17, 17 Pro and 17 Pro Max.
The iPhone Air and iPhone 17e only need a 20W adapter for their top speed (50% in about 30 minutes). No iPhone 17 model comes with a charger in the box, just a 1-meter USB-C cable.
What charger does each iPhone 17 model use?
All of them charge over USB-C, and all of them negotiate power with the charger using USB Power Delivery. What differs is how much power each model can take. These are Apple's own figures from its spec and fast-charge support pages.
| Model | Adapter for top wired speed | Apple's wired claim | MagSafe (with adapter) |
|---|---|---|---|
| iPhone 17 | 40W or higher | 50% in 20 min | 25W, 50% in 30 min (30W+) |
| iPhone 17 Pro / 17 Pro Max | 40W or higher | 50% in 20 min | 25W (30W+ adapter) |
| iPhone Air | 20W or higher | 50% in 30 min | 20W, 50% in 30 min (30W+) |
| iPhone 17e | 20W or higher | 50% in 30 min | 15W (20W+ adapter) |
| iPhone 18 Pro / 18 Pro Max | 60W-capable with AVS | 50% in about 15 min | 25W, 50% in 30 min (35W+) |
| iPhone 16 family (for comparison) | 20W or higher | 50% in 30 min | 22.5W to 25W (30W+) |

Independent testing lines up with Apple's numbers. LTT Labs measured every iPhone 17 model and found none of them drew more than about 38 to 40W before tapering, and a third-party Anker 45W charger matched Apple's own 40W adapter on the iPhone 17 Pro. Their summary: other USB-C PD chargers are fully capable of charging these phones at their maximum rate.
Does the iPhone 17 come with a charger?
No. Apple hasn't put a power adapter in an iPhone box since the iPhone 12. According to Apple's spec pages, the iPhone 17, iPhone Air, iPhone 17e and iPhone 18 Pro all ship with the phone, a 1-meter USB-C Charge Cable, and documentation. You bring the wall charger. Apple sells its 40W Dynamic Power Adapter with 60W Max for $39, without a cable.
How fast will your charger charge an iPhone 17?
Pick a phone and the charger you actually have. Where Apple publishes a figure for that combination, you'll see it tagged as Apple's. Everything else is our estimate, scaled from Apple's numbers and LTT's measurements, and shown as a range because temperature, battery age and background use all move it.
Time from empty to 50%
The second half of a charge is always slower than the first as the phone tapers to protect the battery, so 0 to 100% takes much more than double.
Will my old charger work with the iPhone 17?
Almost certainly, yes. USB-PD is a negotiation: the phone and the charger agree on a voltage and current both can handle, so a small charger just charges more slowly and a big one never pushes more than the phone asks for. In practice:
- Apple 20W USB-C adapter: works fine. It's the right speed for an iPhone Air or 17e, and about iPhone-16-class speed on a 17 or 17 Pro.
- 30W or 35W USB-C adapters: good. Apple's MagSafe Charger needs 30W to reach 25W wireless, and wired charging lands between the 20W and 40W times.
- MacBook chargers (67W, 70W, 96W, 140W): safe and fast. The phone takes what it needs, around 40W at most on a 17 Pro.
- Old USB-A bricks (5W, 12W): they work with a USB-A to USB-C cable, but Apple says iPhone 15 and later charge at a maximum of 7.5W from any USB-A charger, so expect the Slow Charger notice. Our Slow Charger guide explains that message.
- Lightning chargers with a built-in cable: won't fit. The iPhone 17 has a USB-C port.
Which cable do you need?
The cable in the box is fine for everything up to 60W. Any USB-C to USB-C cable rated for 60W (3A) handles every iPhone 17 model at full speed; a 240W cable adds nothing for a phone but is handy if the same cable charges a laptop.
Is my cable holding my iPhone back?
Is 40W fast charging bad for the iPhone 17 battery?
Not in any way you should worry about. The phone controls the charge rate, not the charger, and it only runs at peak power in the lower part of the battery before tapering. Heat is what ages lithium-ion batteries, and the iPhone slows charging on its own when it gets warm. If you want to baby the battery, the settings that matter more are Optimized Battery Charging and the charge limit in Settings, Battery. We dug into the MagSafe side of this in does MagSafe charging damage battery health.
What charger does the iPhone 18 Pro use?
Same USB-C port, same cable, one new wrinkle. Apple quotes the iPhone 18 Pro and 18 Pro Max at 50% in about 15 minutes, but only with a "60W-capable adapter or higher with Adjustable Voltage Supply," such as Apple's 40W Dynamic Power Adapter with 60W Max. AVS is part of the USB-PD 3.2 spec and plenty of chargers don't support it yet.
9to5Mac tested what happens without it: a regular 40W+ USB-C PD charger charges the 18 Pro at roughly iPhone 17 Pro speed, about 20 minutes to 50%. That's five minutes slower than Apple's headline and still very quick. Unless you're chasing the last five minutes, the charger you'd buy for an iPhone 17 is the right one for an 18 Pro.
Being straight about our own charger: the GripLux HyperGaN is a USB-C PD charger. Its casing lists USB-C1 at PD 65W, USB-C2 at PD 25W and a Quick Charge 5.0 USB-A port. We don't claim AVS support, so on an iPhone 18 Pro expect the roughly 20-minute result above, not Apple's 15.
One charger for the iPhone 17 and everything else
The HyperGaN's 65W USB-C port covers the iPhone 17's roughly 40W peak with room to spare, and the second USB-C port handles an iPhone Air, 17e, AirPods or a MagSafe charger. It's the brick we'd point an iPhone 17 owner to, and yes, we sell it.

iPhone 17 charger FAQ
What charger does the iPhone 17 use?
A USB-C charger that supports USB Power Delivery, with a USB-C to USB-C cable. Any USB-C PD charger works; a 40W or higher adapter gives Apple's fastest speed of 50% in about 20 minutes on the iPhone 17, 17 Pro and 17 Pro Max.
Does the iPhone 17 come with a charger?
No. The box includes the iPhone and a 1-meter USB-C Charge Cable, but no power adapter. Apple stopped including adapters with the iPhone 12.
Can I use a 20W charger with the iPhone 17?
Yes. It's safe and it works well, just slower than a 40W charger on the 17, 17 Pro and 17 Pro Max. For the iPhone Air and iPhone 17e, 20W is all you need for their fastest wired speed.
Do I need Apple's 40W Dynamic Power Adapter?
No. Any USB-C PD charger that can supply about 40W reaches the same speed on an iPhone 17; LTT Labs found an Anker 45W charger matched Apple's. Apple's adapter matters more for the iPhone 18 Pro, which needs Adjustable Voltage Supply for its 15-minute claim.
Can I charge my iPhone 17 with a MacBook charger?
Yes. MacBook USB-C chargers (67W, 70W, 96W, 140W) are USB-PD chargers, and the iPhone only draws the power it can use, around 40W at peak. It's a safe and fast option.
What cable does the iPhone 17 use?
USB-C to USB-C. The 1-meter cable in the box supports full-speed charging. Any USB-C cable rated for 60W (3A) or more will do the same.
How fast does the iPhone 17 charge wirelessly?
Up to 25W on Apple's MagSafe Charger or a Qi2 25W charger, with a 30W or larger adapter behind it. Apple quotes 50% in about 30 minutes that way.
Is 40W charging bad for the iPhone 17's battery?
No. The phone manages the charge rate, peaks only at low battery levels and throttles when warm. Heat matters more than wattage, and Optimized Battery Charging or the charge limit setting do more for long-term battery health.
