iPhone 15 uses USB-C, not Lightning
The iPhone 15 and iPhone 15 Plus charge with USB-C, a change Apple made in 2023. If you own an older iPhone (6 through 14), your Lightning cables and chargers will not work with iPhone 15. You will need a new USB-C cable and a USB-C power adapter, or you can use a USB-C cable with any USB-C charger you already own for other devices.
Apple includes a USB-C to USB-C cable in the iPhone 15 box, but does not include a power adapter. You have to buy the adapter separately, or use one you already have. This is the same approach Apple took with iPhone 14 and later models.
The good news: USB-C chargers are now standard across phones, tablets, and laptops. If you own an Android phone, iPad, MacBook, or other modern device, you likely already have a USB-C power adapter that will work with iPhone 15.
Key Takeaways
- iPhone 15 comes with a USB-C cable but no power adapter, so you must buy an adapter separately or use one you already own.
- Any USB-C power adapter will charge iPhone 15, whether it came with another device or is a third-party brand.
- Lightning cables and chargers from older iPhones will not work with iPhone 15.
- Fast charging on iPhone 15 requires a USB-C power adapter rated 20 watts or higher, paired with the included USB-C cable.
- Wireless charging still works with iPhone 15 using any Qi-certified wireless charger.
What power adapter wattage you actually need
iPhone 15 will charge with any USB-C power adapter, but the wattage determines how fast it charges. A 5-watt adapter (the smallest common size) will charge iPhone 15, but slowly — it may take 3 to 4 hours to fully charge from empty. A 20-watt adapter cuts that time roughly in half. A 30-watt or higher adapter charges even faster, though iPhone 15 caps out at around 25 watts of charging speed, so anything above 30 watts does not make it charge faster.
For most people, a 20-watt USB-C adapter is the practical choice. It charges iPhone 15 in a reasonable time and costs less than higher-wattage models. If you already own a 30-watt, 45-watt, or 65-watt USB-C adapter (from a laptop or tablet), it will work fine with iPhone 15 and charge it at full speed.
The cable also matters. The USB-C to USB-C cable that comes with iPhone 15 supports fast charging. Older USB-C cables or cheap third-party cables may charge iPhone 15, but slower. If you buy a separate cable, look for one labeled as USB 2.0 or USB 3.0 rated for at least 3 amps.
Where to buy a USB-C charger for iPhone 15
Apple sells official USB-C power adapters on its website and in Apple Stores, in 20-watt, 35-watt, and higher sizes. These are reliable but cost more than third-party options — typically $19 to $39 depending on wattage.
Third-party USB-C adapters from brands like Anker, Belkin, and Amazon Basics work with iPhone 15 and cost less, usually $10 to $25. Look for adapters that are certified by USB-IF (the USB standards body) or carry a "USB-C Power Delivery" label. These certifications mean the adapter meets safety and performance standards.
You can buy USB-C adapters at electronics retailers like Best Buy, online at Amazon, or at big-box stores like Target and Walmart. If you need a charger right away, a local electronics store or Best Buy will have stock. If you are willing to wait a few days, online retailers often have lower prices.
Wireless charging still works the same way
iPhone 15 supports Qi wireless charging, the same standard as iPhone 14 and earlier models. Any Qi-certified wireless charger will work with iPhone 15 — you do not need to buy a new wireless charger just because you switched to USB-C.
Wireless charging on iPhone 15 is slower than wired USB-C charging. A typical wireless charger delivers 7.5 to 15 watts, while USB-C wired charging reaches 25 watts. Wireless charging is most useful for overnight charging or when you want to set your phone down without plugging in a cable.
If you own a MagSafe wireless charger (Apple's magnetic charging system), it works with iPhone 15 the same way it worked with iPhone 12, 13, and 14. MagSafe chargers snap magnetically to the back of iPhone 15 and align the charging coil automatically.
What to do with your old Lightning chargers
If you have Lightning cables and power adapters from an iPhone 14 or earlier, they will not work with iPhone 15. You have a few options: keep them for an older iPhone you still use, donate them, sell them online, or recycle them.
Some people donate old Lightning chargers to friends or family members who still use older iPhones. Online marketplaces like eBay, Facebook Marketplace, or Craigslist have buyers for used Lightning cables and adapters, though prices are low since they are no longer the standard.
If you do not want to sell or donate them, most electronics retailers and Best Buy locations have recycling programs that accept old chargers and cables for free. Apple Stores also accept old chargers for recycling. Do not throw them in the trash — chargers contain materials that should be recycled.
Multi-device chargers that work with iPhone 15
If you own multiple devices — an iPhone 15, iPad, MacBook, or Android phone — a single multi-port USB-C charger can power all of them. These chargers have two, three, or four USB-C ports and let you charge multiple devices at once from one adapter.
Popular multi-port options include the Anker 735 Charger (65 watts, three USB-C ports), the Belkin BoostCharge Pro (140 watts, four ports), and the Apple 140W USB-C Power Adapter (which has two USB-C ports). Multi-port chargers cost more upfront but save money if you were planning to buy separate adapters for each device.
When using a multi-port charger, the power is shared among all connected devices. If you plug in three devices to a 65-watt charger, each gets roughly 20 watts. This is still fast enough for iPhone 15, but slower than using a single-device charger. For travel or a desk setup, multi-port chargers are convenient and reduce cable clutter.
Frequently Asked Questions
Can I use my old iPhone charger with iPhone 15?
No, if your old charger is Lightning (the connector used on iPhone 6 through 14), it will not work with iPhone 15. iPhone 15 uses USB-C. If your old charger is USB-C (from an iPad, Android phone, or laptop), it will work with iPhone 15.
Do I have to buy an Apple charger or can I use a third-party one?
You can use any USB-C power adapter, including third-party brands. Third-party adapters are usually cheaper and work just as well as Apple's official adapters. Look for USB-IF certification or a "USB Power Delivery" label to ensure safety and performance.
What is the fastest way to charge iPhone 15?
Use the included USB-C to USB-C cable with a 20-watt or higher USB-C power adapter. This combination charges iPhone 15 at its maximum speed of around 25 watts. Wireless charging is slower and takes longer.
Will my wireless charger work with iPhone 15?
Yes, any Qi-certified wireless charger works with iPhone 15, including older chargers from iPhone 8 and later. MagSafe wireless chargers also work with iPhone 15 the same way they worked with iPhone 12 through 14.
Is it safe to use a 65-watt or 100-watt charger with iPhone 15?
Yes, it is safe. iPhone 15 will only draw the power it needs (up to 25 watts for wired charging), so a high-wattage charger will not damage it. High-wattage adapters are useful if you charge multiple devices at once.
