Best iPhone Charger in 2026: The Right Wattage for iPhone 15 to 18 Pro and iPhone Duo

If you have a USB-C iPhone (iPhone 15 or later), the charger most people should buy is the Anker Nano Charger (45W). It clears the 40W that Apple says the iPhone 17, 17 Pro and 17 Pro Max need for their fastest wired charge, and it fast charges every older USB-C iPhone too. On a tighter budget, the Anker Nano Charger (30W) covers everything Apple quotes for an iPhone 15 or 16. If you own an iPhone 18 Pro, buy Apple's 40W Dynamic Power Adapter with 60W Max, because Apple's 15-minute figure depends on a charger feature (AVS) that few third-party chargers list yet. The new iPhone Duo needs the most power on a cable: Apple's fastest figure calls for a 60W-capable charger, which the Anker 715 (65W) meets.

The right wattage has changed with almost every iPhone generation, so this guide starts from Apple's own specs.

Quick picks

What wattage does your iPhone actually need?

These figures come from Apple's fast charging support page and each model's tech specs, including the iPhone Duo's. Charge times are Apple's own claims for a drained battery.

Four things follow from that table:

1. For iPhone 15, 16, 16e, 17e and Air, 20W already hits Apple's fastest wired figure. A 30W charger is still worth it, because that's what Apple's MagSafe Charger needs to reach 25W on an iPhone 16 or 17.
2. The iPhone 17 family is the first where more than 30W matters on a cable. Apple quotes 50% in about 20 minutes only with a 40W or higher adapter. A 30W charger still charges it, just not to that figure.
3. The iPhone 18 Pro adds a protocol requirement. Apple's 15-minute figure needs a 60W-capable adapter with Adjustable Voltage Supply (AVS), part of USB Power Delivery 3.2. Other USB-C PD chargers still charge it, but Apple doesn't quote 15 minutes for them.
4. The iPhone Duo needs the most watts on a cable. Apple quotes 50% in around 20 minutes only with a 60W-capable USB PD adapter, so the 45W chargers that suit an iPhone 17 fall short of Apple's figure. Apple doesn't list AVS for the Duo, so any 60W-or-higher USB-C PD charger meets its spec on paper.

Why a higher-wattage charger is safe

USB Power Delivery is a negotiation. The charger announces the voltages it can supply, and the iPhone picks one and draws only the current it wants. A 100W laptop charger connected to an iPhone delivers what the iPhone asks for, which is far less than 100W. Apple says so directly: a 20W or higher-wattage USB-C power adapter, "like the one that came with your Mac laptop," can charge your iPhone faster.

So extra watts are headroom, not risk, and they don't push an iPhone past Apple's figure because the phone sets the pace. The real risks are counterfeit chargers and frayed cables, which is why every pick here comes from a brand that publishes full output specs.

What AVS adds. Classic USB PD offers a handful of fixed voltages. AVS lets the phone request a voltage in fine steps between them; Apple says it "precisely adjusts voltage" for a more efficient charge. That's why Apple names its 40W Dynamic adapter for the iPhone 18 Pro.

Best overall: Anker Nano Charger (45W, Smart Display)

Anker's spec sheet lists 45W from one USB-C port (5V/3A, 9V/3A, 15V/3A and 20V/2.25A), comfortably above the 40W Apple specifies for an iPhone 17, 17 Pro or 17 Pro Max to reach 50% in about 20 minutes. Anker's own lab claim matches: an iPhone 17 Pro to 50% in about 20 minutes.

The small display shows live wattage and temperature, plus the phone model and battery level for iPhone 15, 16 and 17 models (not the 17e). Care Mode caps output at 20W for gentler overnight charging. The US prongs lock at 90° or 180°, so it can sit flat behind a nightstand, and the body is 1.34 x 1.40 x 1.57 inches at 2.65 ounces.

Two caveats: Anker doesn't list AVS for this version, so an iPhone 18 Pro charges over standard USB PD rather than at Apple's 15-minute rate, and there's no cable in the box. This listing is the Orange model.

Best budget: Anker Nano Charger (30W)

If your phone is an iPhone 15, 16, 16e, 17e or Air, this is all the wired charger you need. Anker lists 30W from one USB-C port (5V/3A, 9V/3A, 15V/2A and 20V/1.5A), above the 20W Apple uses for its 50%-in-30-minutes figure on those models. The headroom matters with Apple's MagSafe Charger, because an iPhone 16 or 17 only reaches 25W wireless when the adapter behind the puck is 30W or higher.

It's tiny, at 1.12 x 1.12 x 1.39 inches with a foldable plug, and it supports PPS for Samsung phones too. On an iPhone 17 it sits below the 40W Apple uses for its 20-minute figure. There's no cable in the box.

Best for iPhone 18 Pro: Apple 40W Dynamic Power Adapter with 60W Max

Apple's support page names this adapter for the iPhone 18 Pro, and its spec sheet shows why. Apple lists AVS output ranges of 9-15V and 15-20V alongside standard 5V and 9V profiles, 40W of continuous power, and the ability to "dynamically deliver up to 60W." That meets the "60W-capable adapter with AVS" requirement behind the 18 Pro's 15-minute figure. It's also the adapter Apple used for its iPhone 17 charging figures.

It has one port and folding US prongs, and it also charges an iPad or a MacBook Air. No cable is included; Apple's figures assume a 60W-capable USB-C cable like the one in the iPhone box. If you don't have an iPhone 18 Pro, the Anker 45W above meets Apple's iPhone 17 requirement on paper and adds a display.

Best for iPhone Duo: Anker 715 Charger (Nano II 65W)

The iPhone Duo, Apple's first foldable, goes on sale October 23 and has the highest wired requirement of any iPhone so far. Apple's tech specs quote 50% in around 20 minutes with a "60W-capable adapter or higher," and the footnotes ask for a USB Power Delivery adapter and a 60W-capable USB-C cable. Unlike for the iPhone 18 Pro, Apple doesn't list AVS for the Duo.

Anker lists 65W from one USB-C port (5V/3A, 9V/3A, 15V/3A and 20V/3.25A), so it meets that spec on paper, with enough left over to charge a MacBook Air. Apple measured its own figure with the 40W Dynamic Power Adapter with 60W Max above, so buy that one if you want exactly the setup Apple tested.

The Anker also covers MagSafe. The Duo charges at up to 25W wirelessly, and Apple quotes 50% in about 30 minutes with a MagSafe Charger behind a 35W or higher adapter. The Duo comes with a 1 m USB-C Charge Cable but no power adapter.

It has one port, so it charges one device at a time, and at 1.65 x 1.42 x 1.74 inches with a foldable plug it's a little bigger than the Nano chargers above.

Best for iPhone + Apple Watch: Apple 35W Dual USB-C Port Compact Power Adapter

Apple publishes exactly how this two-port adapter splits its 35W. A single device gets up to 35W from either port. An iPhone plus an Apple Watch or AirPods gets up to 27.5W and 7.5W, so the iPhone still gets more than the 20W behind Apple's iPhone 15 and 16 fast-charge figure. A MacBook Air or iPad plus an iPhone splits evenly at up to 17.5W each.

That makes it a strong phone-and-watch charger and a reasonable MacBook Air travel charger, which Apple recommends it for. The prongs fold. On paper, 35W is below the 40W Apple specifies for the iPhone 17 family's 20-minute figure, and Apple doesn't list AVS for it. No cables are included.

Best wireless with the adapter included: Belkin UltraCharge 2-in-1

This stand solves the problem that trips up most MagSafe buyers: the power adapter. Belkin includes a 45W USB-C power supply and a 5 ft braided cable, so the stand always gets enough power. It's Qi2.2 25W certified. Belkin says Qi2 25W-certified phones charge at up to 25W and other Qi2 phones at up to 15W, and quotes an iPhone 16 on iOS 26 or newer going from 0 to 50% in 29 minutes.

Apple's specs line up: Qi2 at up to 25W on the iPhone 16 and 17 lines, the iPhone 18 Pro and the iPhone Duo, 20W on the iPhone Air, and 15W on the iPhone 15 and 17e. The base adds a 5W AirPods pad and a 5W USB-C port for an Apple Watch cable, and it folds to about 106 x 60 x 24 mm (162 g) for travel.

There's no built-in watch puck, and Belkin lists cases up to 3 mm thick. The iPhone 16e has no MagSafe magnets, so it won't hold on the stand. This listing is the White model.

Which cable?

The USB-C cable in your iPhone box works with every charger here. Every USB-C to USB-C cable must carry at least 3A (60W at 20V), which covers the 60W-capable cable Apple asks for with the iPhone 18 Pro. For spares, the Anker 240W braided two-pack gives you a 3 ft and a 6 ft cable that also charge a laptop. iPhone 15 and later need USB-C to USB-C; USB-C to Lightning is only for iPhone 14 and earlier. Our fast-charging cable guide explains when cable ratings start to matter.

The iPhone Duo's port also supports USB 3 at up to 10Gb/s and 4K HDR video out over DisplayPort. Apple says those speeds need a USB 3 cable rated for 10Gb/s, so check a cable's data rating as well as its wattage. Our USB-C cable types explainer shows how to tell them apart.

How we choose

We haven't put these chargers on a test bench. Our picks come from research:

• Apple's own numbers first. The table above comes from Apple's fast charging page and each iPhone's tech specs, and we sized every pick against it.
• Manufacturer spec sheets. Every output, port split and dimension comes from the maker's product page. Where a maker doesn't publish something, such as AVS support, we say so instead of assuming.
• Standards and buyer patterns. USB PD voltages, PPS, AVS and cable minimums, plus well-known issues such as slow MagSafe charging from an underpowered adapter.

Buying guide

Match the charger to the phone, not the biggest number. Apple's fastest wired figure for an iPhone 15 or 16 needs only 20W, so a 100W brick only makes sense if it also charges a laptop. The iPhone 17 family is where 40W+ pays off, the iPhone 18 Pro is where AVS comes in, and the iPhone Duo is the first iPhone that needs a 60W-capable charger.

For MagSafe, the adapter matters as much as the puck. Apple's MagSafe Charger needs 30W or more for 25W on iPhone 16, 17 and Air, and 35W or more for the iPhone 18 Pro's and iPhone Duo's quoted times. iPhone 15 models top out at 15W wirelessly regardless.

Retire the old USB-A cube. Old 5W USB-A cubes can't do USB Power Delivery, so they charge slowly. Our USB-C vs USB-A explainer covers why.

Already own a laptop charger? It fast charges an iPhone safely; see our best USB-C chargers for one brick that does both. For trips, see our travel charger guide and our power bank guide. And remember that iPhone 15 and later can charge AirPods or an Apple Watch over USB-C at up to 4.5W.

Verdict

Buy the Anker Nano Charger (45W) for one small charger that meets Apple's fastest wired figure on every USB-C iPhone up to the iPhone 17 family. The Anker Nano Charger (30W) is enough for an iPhone 15, 16, Air or 17e. iPhone 18 Pro owners should get the Apple 40W Dynamic Power Adapter. For the iPhone Duo, get the Anker 715 (65W), or Apple's 40W Dynamic adapter to match Apple's own test setup. Get the Apple 35W Dual for a phone and a watch on one outlet, or the Belkin UltraCharge 2-in-1 to charge on a stand.
