How to fast charge your iPhone

While they may not be some of the longest-lasting smartphones on the market, modern iPhones boast more than respectable battery life that should be able to get you through an entire day’s use without breaking too much of a sweat. Of course, that assumes a lot of things — including a battery that’s still relatively new and in good health, plus a usage pattern that doesn’t include all-day streaming or gaming.

But for some people, overnight charging isn’t going to cut it, and you’ll want to get your battery topped up again as quickly as you can so you can get back in action. Thankfully, every iPhone released in the past six years supports much faster charging, but the downside is that with very few exceptions, Apple has never supplied you with the right adapter to get the best possible charging speeds from your iPhone.

Fortunately, it’s not hard to find the right tools for the job. If you’re tired of suffering from battery anxiety or waiting hours for your iPhone to charge, you’ve come to the right place. We’ll explain how this works and what you need to ensure that your iPhone charging experience will be as fast and smooth as possible.

What is fast charging, and why can’t my charger do it?

We’ve written a comprehensive guide to fast charging, but let’s do a quick review. Fast charging uses a newer USB technology called USB Power Delivery (USB PD) that’s available as part of the USB-C standard. It’s a very flexible and efficient option that can optimize power management. By upgrading to a USB PD connection, you can achieve charging speeds far faster than those provided by Apple’s traditional chargers.

Although Apple stopped supplying chargers in the box with the 2020 release of the iPhone 12, the 5W charger that it used to package with nearly every iPhone isn’t capable of fast charging. It’s fine for juicing up an iPhone overnight, and the slower charging rate can even be better for the battery. But during daytime hours, you’re really not going to want to wait for the five or six hours it would to fully recharge an iPhone 16 Pro Max with one of these older adapters.

Charging an iPad with a 5W power adapter can take even longer, which is why Apple has always supplied more powerful 10W or 12W adapters in the box. If you have an older iPad charger, you can also use it for faster iPhone charging too — it should cut the charging time in half and won’t harm your phone in any way since the phone will never draw more power than it can handle.

Still, those 12W adapters still use older USB-A connections and don’t support the USB PD standard, so they aren’t technically what’s considered “fast charging” by today’s standards.

While Apple was a bit late to the game on this, it brought true fast charging to the iPhone 8 lineup in 2017, and it’s been supported on every iPhone released since then, with support for charging speeds of 18W and beyond. However, despite this improvement, Apple continued to pack in the old 5W charger with most iPhones. The only iPhone models to include the USB-C fast charger in the box were the iPhone 11 Pro and iPhone 11 Pro Max; with every other model, you had to buy the proper charger separately if you wanted the fastest possible charging speeds.

If you’re wondering how much faster fast charging is, Apple claims it will refill up to 50% of your iPhone’s battery in a mere 30 minutes. This means you can finally say goodbye to waiting for your phone to charge and bid farewell to overnight charging. Needless to say, fast charging will ease the anxiety you get when you’re about to head out the door and realize your phone is at 17%.

Note that this is only the beginning of fast charging trends. In 2020, Oppo revealed a 125W charger that can charge a 4,000mAh battery in 20 minutes. Since then, many Android makers have pushed charging speeds to this same level or even higher, so Apple may have some catching up to do here.

How fast can my iPhone charge?

The speed at which your iPhone charges depends on the model. Apple doesn’t like to reveal its phones’ charging specs every time it releases a new series of iPhones, but there’s a pattern during the process. The iPhone charges faster when its battery life is in the red (somewhere between 1% and 10%), only to slow down a tad once it reaches 50% to avoid overheating your phone. Here are the maximum fast charging speeds of every iPhone model that can run iOS 18.

Apple’s official fast charger

While Apple doesn’t supply a fast charger with many of its iPhones, it does sell a fast charger in the form of a new cable and charging brick for your device. This is far from the least expensive option, but if you’re happy to spend the money to get your charger straight from Apple, here’s what you need.

The cable

You’ll need to use a USB-C connection for this fast-charging option on your iPhone. The good news is that Apple included this USB-C to Lightning cable in the box since the iPhone 12 — at least, until it sunsetted the Lightning connection. The iPhone 11 Pro and iPhone 11 Pro Max also included not only the cable, but also Apple’s first 18W USB-C power adapter, giving you everything you need for the fastest charging. However, if you have an older iPhone, you can also buy one directly from Apple. They’re guaranteed to work with your iPhone and come in one and two-meter versions.

This woven USB-C charger cable has been packaged with the iPhone since the iPhone 15, but you can get it as a standalone item in case you need an extra cable or need to replace one you lost. For environmental reasons, Apple hasn’t packed the power adapter with this cable for the recent iPhone models. It supports charging up to 60W — not that the iPhone would charge that quickly — and transfers data to and from your computer at USB 2 rates. It comes in one- and two-meter versions, however long you need to charge your phone faster.

The power adapter

Along with the fast-charging cable, you’ll need a particular charging brick because what’s an Apple product without a bunch of peripherals? Apple’s solution is a 20-watt adapter with a USB-C port rather than the standard USB-A port. If you’re looking to fast-charge an iPhone at a decent speed, then this $29 official 20-watt USB-C power adapter is a good and well priced option.

If you have a newer MacBook or iPad, you may already have a power adapter that can handle all your fast-charging needs. Almost all MacBooks and iPads sold in the past few years use USB-C-compatible charging blocks, and you can plug your USB-C to Lightning cable into this adapter to fast charge your iPhone.

If you’re rocking a MacBook Pro, you likely have a charger that’s even more powerful than the 29W or 30W varieties. Apple has confirmed that even the 61W and 87W versions are safe to use with the iPhone. Remember, your iPhone doesn’t draw any more power than it needs, so a more powerful adapter can’t force your phone to accept a wattage that’s too high for it to handle.

Apple also released a new 35W Dual USB-C Port Power Adapter alongside last year’s redesigned M2 MacBook Air that lets you charge your iPhone and MacBook at the same time. However, it’s important to note that this only supplies 35W of total power, and that’s divided 50-50 — 17.5W each — between your MacBook and iPhone when charging both devices simultaneously.

Note: If you’re buying an adapter just for fast charging, there’s no need to buy an adapter stronger than 30W; even the newest iPhones can only handle a 29W charge under ideal conditions, so a more powerful charger would just cost more money and not offer any extra benefits.

The alternative options

Apple doesn’t hold a monopoly where iPhone fast chargers are concerned, and you’ll find alternatives elsewhere that will deliver the same performance at a much lower price or with additional durability or features.

Note: While we’ve endeavored to select only the best brands and recommended products, we haven’t tested all of the products below, so use them at your own risk, and know your mileage may vary.

Alternative charging cables

It can be pretty tough to find a USB-C-to-Lightning cable that doesn’t come from Apple, and that’s because Apple is strict about who can sell it. One of the few manufacturers allowed to create such cables is the rugged accessories creator Nomad, and while expensive, Nomad’s USB-C-to-Lightning cable is an excellent choice if you need a tougher cable.

It measures 1.5 meters, so it’s slightly longer than Apple’s standard cable, but the real magic is in its toughness. It’s protected by a tightly wound Kevlar braid and has additional protection around the connector, thus ensuring the cable can survive even the worst punishment. It’s expensive, mind you, but it’s backed up by Nomad’s five-year warranty as opposed to Apple’s one-year limited warranty, which takes the sting out somewhat.

Courtesy of Basesailor, this two-pack USB-C charger cable set will help you charge your iPhone quickly at home and in your car. These chargers help provide 3A of fast charging power, and you don’t have to worry about having a USB-C wall adapter since it has a USB-A tail on one end of the cable — you can still use the USB wall adapter lying around your room and the USB adapter in your car. Plus, even if you switch to a Samsung Galaxy or Google Pixel phone, you can save money by keeping the chargers since those phones have USB-C ports, too.

Alternative power adapters

You can grab any power adapter with a USB-C port and enough power, but make sure it supports USB Power Delivery (USB PD) and stick to reputable brands.

is an excellent alternative if you’re looking for something small and affordable. Thanks to gallium nitride (GaN) technology, this little charger manages to be both smaller and more powerful than Apple’s alternative. With 30W of USB-C power delivery, it’s more than capable of handling the fastest charging speeds of any iPhone on the market.

Here’s another Anker power adapter with USB-C and USB-A ports. It delivers 20W of fast charging speed to your iPhone regardless of whether you’re using an all USB-C cable, a USB to USB-C cable, or a USB-C to Lightning cable. You can also use it to charge all your other Apple devices or phones from other brands for a modest price.

To wrap up, you might also want to consider a wireless charging pad. Wireless chargers will juice up your iPhone at respectable speeds, but they’re still slower than any of the wired chargers on our list.

The highest wattage any iPhone can get from a standard Qi wireless charging pad is 7.5 watts (although that may change with this year’s iPhone 15 rumored to adopt the Qi2 standard) However, you might want to choose a charger that can handle a higher wattage to anticipate future capabilities or charge other non-Apple devices. The 10W Belkin Wireless Charger for $25 and the Aukey Aircore 15W for $17 are both worthy options.

If you have an iPhone 12 or a newer model, you can also take advantage of Apple’s MagSafe feature, which allows for charging speeds of up to 15W — twice what you’ll get from a non-MagSafe charger.

These chargers magnetically attach to the back of an iPhone 12 or newer and display an animated ring on the iPhone screen to confirm that you’re taking advantage of the fastest MagSafe charging speeds.

Be careful when shopping for a MagSafe charger. Many third-party accessory makers have added a ring of magnets to a standard Qi charger so they’ll attach nicely to an iPhone, and they sometimes advertise these as “MagSafe-compatible.” However, only genuine MagSafe chargers certified by Apple will provide faster 15W speeds. You should be fine if you stick with an established Apple partner brand such as Belkin, Mophie, or Scosche. These companies also sell regular Qi magnetic chargers, but they’re careful to avoid the word “MagSafe” for those, so you’ll always be sure which one you’re getting — just try and avoid phrases “MagSafe-compatible” as that generally means they have the magnets, but not the faster-charging speeds.

For stand-alone charging, you can’t go wrong with Apple’s MagSafe Charger, but if you want to juice up your AirPods and Apple Watch at the same time, check out Belkin’s BoostCharge Pro 3-in-1 charger or Mophie’s 3-in-1 Travel Charge with MagSafe (pictured above).

You can also use MagSafe-certified chargers with older iPhone models, but they’ll work like any other Qi-compatible charger. Spending the extra money is a good way to be ready when you update to a newer iPhone, but there’s no advantage to using a MagSafe charger with a non-MagSafe iPhone.

See our list of the best wireless chargers for some other great wireless charging options. We also have a roundup of the best MagSafe accessories for your iPhone 12, iPhone 13, or iPhone 14, which includes MagSafe-certified chargers and stands, cases, car mounts, and even battery packs that can take advantage of the magnetic attachment to newer iPhone models.

Final charging tips

Regardless of which charger you buy, make sure to follow these speed and safety tips:

  • Never charge near a heater, in direct sunlight, or any other source of heat. Higher temperatures aren’t good for your battery, and charging will just make an already hot iPhone even hotter. This can damage your iPhone while it charges and lead to increased charging time as the iPhone slows down its power intake to keep from overheating.
  • You can always put your iPhone into Airplane Mode to help speed up charging time.
  • Generally, a wall or power strip outlet will charge faster than a computer.
