What Charger Does the iPhone 18 Use? USB-C, Wattage & MagSafe Explained

Just unboxed a new iPhone 18 Pro or Pro Max and found only a cable inside? You're not alone. The iPhone 18 charger question is one of the most-searched topics since launch, because Apple still doesn't include a power adapter in the box, and the 18 Pro charges faster than any iPhone before it. The catch is that you only get that speed if you pair it with the right adapter.

Here's the short answer: the iPhone 18 Pro and Pro Max charge over USB-C. For the fastest wired charging you need a USB-C Power Delivery adapter that can deliver 60W and supports Adjustable Voltage Supply (AVS). For wireless, the 18 Pro supports MagSafe and Qi2.2 at up to 25W. Below we break down exactly which charger to buy, which old chargers still work, and how your case affects charging.

The Quick Answer: iPhone 18 Charger Specs at a Glance

Apple's charging times are measured on drained phones in testing conditions. Real-world results vary with temperature, what you're doing on the phone, and whether Optimized Battery Charging is holding the phone at 80%.

Does the iPhone 18 Come With a Charger?

No. The iPhone 18 Pro and Pro Max ship with a USB-C to USB-C charging cable, but no power adapter. Apple dropped the in-box adapter back in 2020 and hasn't brought it back. If you're coming from an older iPhone, you probably already have a USB-C brick somewhere. The question is whether it's powerful enough to unlock the 18 Pro's new charging speeds.

The good news: the included cable is rated for 60W, so you don't need to buy a new cable to get full wired speed. You only need the right adapter.

Wired Charging: Why AVS Matters on the iPhone 18 Pro

The headline upgrade this year is wired charging. Apple says the iPhone 18 Pro can reach up to 50% in about 15 minutes with a compatible 60W adapter. That's a meaningful jump over the iPhone 17 Pro, which topped out at roughly 50% in 20 minutes.

The key term is Adjustable Voltage Supply (AVS), part of the USB Power Delivery 3.1 spec. An AVS charger can fine-tune its output voltage in small steps, so the phone can draw high power with less wasted heat. Without AVS, the iPhone 18 Pro falls back to standard USB-C fast charging: still quick (around 20 minutes to 50% on a 40W+ adapter), but not the new top speed.

Apple's own adapter

Apple sells the 40W Dynamic Power Adapter with 60W Max for $39. It supports AVS and can deliver up to 60W when the phone asks for it, which makes it the simplest way to get the full 15-minute-to-50% experience. It's also the adapter Apple used in its own charging tests.

Third-party adapters

Plenty of GaN chargers from Anker, Belkin, UGREEN and others now list USB PD 3.1 with AVS. When shopping, check the spec sheet for three things:

• USB-C Power Delivery 3.1 (older PD 3.0 chargers won't have AVS)
• AVS support explicitly listed
• 60W or more on a single port (multi-port chargers often split power when two devices are plugged in)

If a charger only says "PD 65W" with no mention of AVS, it will still charge your 18 Pro safely and quickly. It just won't hit the absolute fastest rate.

Will my old 20W iPhone charger work?

Yes. Any USB-C power adapter works with the iPhone 18, including Apple's old 20W brick. It'll simply charge slower, which is perfectly fine for overnight charging. The phone negotiates power with the charger, so you can't damage it by using a smaller or larger adapter.

Lightning chargers are a different story. The iPhone 18 has a USB-C port, so Lightning cables won't plug in. If your adapter has a USB-A port, you'll need a USB-A to USB-C cable, and speeds will be limited.

Wireless Charging: MagSafe and Qi2.2 on the iPhone 18

The iPhone 18 Pro and Pro Max support wireless charging at up to 25W through either Apple's MagSafe Charger or a Qi2.2-certified charger. Apple quotes about 30 minutes to 50% with a compatible MagSafe Charger.

To actually hit 25W wirelessly, the charger itself needs enough power going in. Apple specifies a 35W or higher USB-C adapter for its latest MagSafe Charger. Plug that same puck into a 20W brick and it will work, but at reduced speed.

Old MagSafe and Qi chargers

• Original MagSafe Charger (model A2140): works, capped at 15W.
• Original Qi2 chargers: work, generally at 15W.
• Older Qi (non-magnetic) pads: work, but slowly, and alignment matters because there are no magnets holding the phone in place.

If you charge wirelessly every night, 15W is plenty. If you top up at your desk during the day, a current MagSafe Charger or Qi2.2 stand is a worthwhile upgrade.

Wired vs. wireless: which should you use?

Wired is faster and more efficient. Wireless is more convenient and puts zero wear on the USB-C port. Wireless charging does generate more heat, and heat is what ages a battery, so if you're a heavy wireless user, keep Optimized Battery Charging switched on and avoid charging under a pillow or in direct sunlight.

Does Your Case Affect iPhone 18 Charging?

This is the part most charger guides skip, and it's where a lot of slow-charging complaints actually come from.

Wired charging is only affected if the case's port cutout is too tight for your cable's connector. Thick rugged cases sometimes block chunkier third-party USB-C plugs.

Wireless charging is much more sensitive. MagSafe and Qi2.2 rely on a magnet ring to align the charging coils precisely. A case without a proper magnetic ring, or a thick case that pushes the phone too far from the charger, can cause:

• Slower charging, because the phone drops below 25W
• The charger detaching when you pick up the phone
• Extra heat, which triggers the phone to throttle charging further

If you use MagSafe, your case needs a built-in MagSafe-compatible magnet ring. That's non-negotiable for full 25W charging.

Our pick for MagSafe users: Dropguys Ultra Slim Clear

The Dropguys Ultra Slim Clear (MagSafe) was built with MagSafe charging in mind. It has a strong built-in magnet ring that snaps onto MagSafe and Qi2.2 chargers cleanly, and its slim profile keeps the phone close to the charging coil so you get full-speed wireless charging without the heat buildup that thicker cases cause. It fits the iPhone 18 Pro and Pro Max, and it shows off your new color, whether that's glacier, burgundy, silver or black.

And like every Dropguys case, it's backed by our 100% money-back guarantee: if your phone breaks in the case, you get your money back. OtterBox, Casetify and Apple don't offer anything like that.

Pair it with the Dropguys MagSafe Wallet

The Dropguys MagSafe Wallet snaps onto the back of a MagSafe case to carry your cards and ID. Pop it off before you drop the phone on a charger: no wallet should sit between your phone and a wireless charger, since cards with magnetic strips or RFID chips don't mix well with charging coils.

Want maximum drop protection?

If you care more about surviving drops than about slimness, the Dropguys Ultimate is our toughest iPhone 18 Pro and Pro Max case. It's still wired-charging friendly with a generous port cutout, and it's covered by the same money-back guarantee.

How other MagSafe cases compare

All of these will charge properly on MagSafe. OtterBox is tough but noticeably bulkier, which can make desk stands feel top-heavy. Casetify is stylish but among the priciest options. Apple's clear case is well made but offers modest drop protection. None of them will pay you back if your phone breaks inside.

Charging Tips to Protect Your iPhone 18 Battery

• Leave Optimized Battery Charging on. It learns your routine and holds the battery at 80% until shortly before you unplug.
• Consider the 80% limit. In Settings > Battery > Charging, you can cap charging at 80% (or other set limits) to reduce long-term wear.
• Avoid heat. Don't charge in a hot car or under bedding. If the phone feels hot while charging wirelessly, a thick or poorly aligned case is often the culprit.
• Use certified gear. Cheap uncertified cables and bricks may not negotiate power correctly and can be a safety risk.
• Protect the port. Pocket lint in the USB-C port is a common cause of "my phone won't charge." A soft, dry toothbrush or a wooden toothpick does the job; never use metal.

iPhone 18 Charger FAQ

What charger does the iPhone 18 Pro need for fast charging?

Any USB-C Power Delivery adapter will fast charge the iPhone 18 Pro. For the fastest speed Apple quotes (about 50% in 15 minutes), you need a 60W-or-higher adapter that supports USB PD 3.1 with Adjustable Voltage Supply (AVS), such as Apple's 40W Dynamic Power Adapter with 60W Max. The cable in the box is already rated for 60W.

Can I use my old iPhone charger with the iPhone 18?

Yes, as long as it has a USB-C output, or you use a USB-A to USB-C cable with an older USB-A brick. Older, lower-wattage chargers are safe to use. They just charge more slowly. Lightning cables won't fit the iPhone 18's USB-C port.

How fast is MagSafe charging on the iPhone 18?

Up to 25W with a current MagSafe Charger or a Qi2.2-certified charger, powered by a 35W or higher adapter. Apple quotes about 30 minutes to 50%. The original MagSafe Charger and first-generation Qi2 chargers still work at up to 15W.

Does a phone case slow down iPhone 18 charging?

It can with wireless charging. A case needs a built-in MagSafe magnet ring and a reasonably slim back to keep the coils aligned and at full 25W. The Dropguys Ultra Slim Clear is designed for exactly that, and it's backed by a 100% money-back guarantee if your phone breaks in the case.

Does the iPhone 18 come with a charger in the box?

No. The iPhone 18 Pro and Pro Max include a 60W-rated USB-C to USB-C cable but no power adapter, so you'll need to use one you already own or buy one separately.
