iPhone 15 comes with a USB-C to USB-C cable and requires a USB-C power adapter

The iPhone 15 charges using USB-C, a change from the Lightning connector that Apple used on iPhones for over a decade. Apple includes a USB-C to USB-C cable in the box, but does not include a power adapter — you need to provide your own USB-C charger or use one you already own.

This means if you have a USB-C power adapter from another device — a recent iPad, Android phone, laptop, or even some older MacBooks — it will work with your iPhone 15. The phone charges faster with higher-wattage adapters, but any USB-C adapter will work.

If you do not own a USB-C power adapter yet, you can buy one separately. Apple sells official adapters in 20W, 35W, and higher wattages, but third-party USB-C adapters from other manufacturers work just as well and often cost less.

Key Takeaways

  • iPhone 15 uses USB-C charging, not the older Lightning connector, and comes with a USB-C to USB-C cable but no power adapter.
  • Any USB-C power adapter will charge your iPhone 15, including adapters from iPads, laptops, and other devices you may already own.
  • Faster chargers (35W and higher) will charge your phone quicker than slower ones, but all USB-C adapters are compatible.
  • You can also charge wirelessly using any Qi-compatible wireless charger, which works the same way it did on previous iPhones.

USB-C power adapters you probably already have

Before you buy a new charger, check what USB-C adapters you already own. Many modern devices ship with USB-C power adapters, and they all work with iPhone 15.

Common sources include recent iPad models (iPad Air, iPad Pro, iPad mini), MacBooks and Mac laptops, newer Android phones like Samsung Galaxy or Google Pixel, Nintendo Switch, and portable battery packs. If any of these devices are in your home, their chargers will work with your iPhone 15.

The wattage printed on the adapter (usually 18W, 20W, 30W, 35W, or higher) tells you how fast it will charge. A 20W adapter is common and charges iPhone 15 at a reasonable speed. A 35W or higher adapter charges faster, but there is no downside to using a slower one — it just takes longer.

Buying a USB-C power adapter if you need one

If you do not have a USB-C adapter, you have two main choices: buy from Apple or buy from another manufacturer.

Apple's official adapters come in 20W, 35W, and higher wattages and cost between $19 and $99 depending on power. They are reliable and carry Apple's warranty, but they are more expensive than alternatives.

Third-party adapters from brands like Anker, Belkin, and others are widely available at electronics stores, big-box retailers, and online. A 20W third-party USB-C adapter typically costs $10 to $15, and a 35W adapter costs $20 to $30. These work just as well as Apple's adapters for charging your iPhone 15, though they do not carry Apple's warranty.

When shopping, look for adapters labeled "USB-C power delivery" or "USB-C PD" — this is the standard that iPhone 15 uses. Avoid very cheap adapters with no brand name, as they may not be safe or reliable.

Wireless charging still works on iPhone 15

iPhone 15 still supports wireless charging using the Qi standard, the same wireless charging pads that worked on older iPhones. You do not need to buy a new wireless charger — any Qi-compatible pad you already own will work.

Wireless charging is slower than wired USB-C charging, but it is convenient if you have a charging pad on your desk or nightstand. You simply place your iPhone 15 on the pad and it begins charging automatically.

If you want to buy a new wireless charger, look for any pad labeled "Qi" or "Qi-certified." Apple also sells an official MagSafe charger that magnetically aligns with your phone, though this is optional and more expensive than standard Qi pads.

Fast charging speeds with different wattages

iPhone 15 charges faster with higher-wattage adapters, but the difference matters most if you are in a hurry. Here is what to expect:

A 20W adapter charges iPhone 15 from zero to about 50 percent in roughly 30 minutes, and to full charge in about 90 minutes. A 35W adapter reaches 50 percent in about 25 minutes and full charge in about 60 minutes. Even higher wattages (65W and above) do not charge significantly faster — Apple's hardware limits how quickly the battery accepts power.

For everyday use, a 20W adapter is sufficient. If you frequently charge in a hurry, a 35W adapter is worth the extra cost. Beyond 35W, you are paying more for speed gains that are very small.

What about MagSafe and other charging accessories

iPhone 15 supports MagSafe, a magnetic attachment system that lets you snap accessories onto the back of your phone. MagSafe works with wireless chargers, car mounts, and other accessories, but it is optional — your phone charges perfectly well without it.

MagSafe chargers are more expensive than standard Qi wireless chargers and offer no charging speed advantage. They are useful if you want a charger that stays magnetically aligned without you having to position it perfectly, but they are not necessary.

You can also buy USB-C car chargers, portable battery packs with USB-C output, and other charging accessories. All of these work with iPhone 15 as long as they have a USB-C port or are Qi-compatible wireless chargers.

Frequently Asked Questions

Can I use my old iPhone Lightning charger with iPhone 15?

No. iPhone 15 uses USB-C, not Lightning. Your old Lightning cables and adapters will not work. However, if you have USB-C adapters from other devices, those will work fine with the USB-C cable included in the iPhone 15 box.

Do I need to buy Apple's charger or can I use any USB-C adapter?

Any USB-C power delivery adapter works with iPhone 15. Third-party adapters from reputable brands are safe and often cheaper than Apple's official adapters. Avoid very cheap adapters with no recognizable brand name.

Is 20W or 35W better for charging iPhone 15?

Both work fine. A 20W adapter charges your phone at a reasonable speed and is sufficient for daily use. A 35W adapter charges faster if you are in a hurry, but the difference is only about 30 minutes for a full charge. Choose based on your budget and how often you need fast charging.

Will wireless charging damage my iPhone 15 battery?

No. Wireless charging is safe and does not damage the battery. It is slower than wired charging, but it is convenient for overnight charging or keeping your phone topped up throughout the day.

What if I lose the USB-C cable that comes with iPhone 15?

You can buy a replacement USB-C to USB-C cable from Apple or any electronics retailer. Third-party cables are cheaper and work just as well. Make sure it is labeled USB-C to USB-C, not USB-C to Lightning or other variants.
