Are you an iPhone user looking to upgrade to… the iPhone? Well, you’ll have more to consider this time around since the new iPhone 15 comes with a USB-C port, ending an 11-year run for the company’s proprietary Lightning charging plug.
USB Type-C (or just USB-C) is the universal charging and data-transferring connector, and it’s now on pretty much every modern gadget, including Apple’s iPads and MacBooks. It might just be the last cable we’ll ever need.
Apple has made us buy new cables before, but this time, you probably already have the things you need to charge your new iPhone. Apple stopped including charging bricks with the iPhone 12 in 2020, but the 15 and 15 Pro do at least come with a short C-to-C cable in the box.
To get the fastest charging speeds on an iPhone 15, you’ll want at least a 20W USB-C charger. If you’ve bought a MacBook since 2015 or an iPad Pro since 2018, their bundled USB-C chargers work splendidly, though they’re bulkier than you really need. You can pick up a tiny 20W GaN charger for under $15. Lots of Verge staffers like this Anker one.
Just about any USB charger will work in a pinch. If the charger has a USB-A port, you’ll need a USB-A-to-C cable to connect to your phone and probably a magnifying glass to try to read its power output settings. USB-A chargers can top out at about 18W, which is close enough, but those are relatively rare. Chargers for lower-powered devices like headphones or older phone chargers — like the little white cubes Apple used to bundle with the iPhone 11 and below — are more likely to be 5W or 10W at best, and they’ll take a long time to charge your phone. Spend the $15 on a good USB-C charger.

As an iPhone user, you might already have Lightning cables set up in each room and would need just to replace the cable while keeping the power adapter where it is. But if you only have the wall warts and somehow have no USB-C cables to use with them (except for the one that will come in the iPhone 15 box), then it’s time to go shopping.
But before you jump on Amazon and toss the first discount cable that’s winning on the site’s search results into your cart, you should know that USB-C cables aren’t something you necessarily want to buy too cheap.
USB-C is a mess. Some cables can fast-charge a MacBook Pro but transfer data at a glacial pace. Others can do fast data transfer but are too short and inflexible to really use for daily charging. Despite some efforts at labeling, it’s nearly impossible to tell at a glance which cables do what.
Anyone can slap a USB-C plug on a cable and sell it online. From time to time, this causes problems. It’s rare nowadays to find a cable that will fry your device, but there’s no reason not to look for USB-IF compliance. The USB Implementers Forum (or USB-IF) invites USB-C cable manufacturers to put their power noodles through compliance testing. Those who do the testing earn themselves a cool logo for their packaging that also lets customers know what kind of charging power and data transfer speeds to expect. When shopping for a cable, try and see if the manufacturer uses a logo or at least states that the cable is certified by USB-IF (and if true, their cable should show up on the USB product search site).
As far as the specific types of cables to look for, here’s the incredibly short version: for charging, you should get a USB-C-to-C cable, USB 2.0, six or 10 feet long, ideally USB-IF-certified. There’s no real reason to get something rated for more than 60W charging, but there’s not much price difference between cables rated for 60W, 100W, or 240W, and a higher-rated cable will work just fine for a phone. Don’t bother with data transfer speed for this cable; you’re not transferring data with it.
Yes, the cable that comes in the box is just fine for charging. It’s just short. A six- or 10-foot cable is much nicer to charge with. A 6.6-foot USB-IF 100W charging cable is under $15.
If you’re planning on copying data from your new iPhone 15 Pro or Pro Max, specifically to get your video footage onto a computer quicker than AirDrop, you’ll need a cable that can transfer data at high speed. The iPhone 15 Pro models support USB 3 at up to 10Gbps, so you’ll need a cable that’s rated for at least 10Gbps. In the newest, simplified USB-IF branding, that’s USB 10Gbps. Older cables might say USB 3.1 Gen 2 or USB 3.2 Gen 1×2 or USB 3.2 Gen 2. A three-foot USB-IF-certified 10Gbps and 100W cable is also under $15.

Unless you’re an ultra-minimalist or you’re buying a cable for your travel kit, get separate cables for your daily charging and data transfer, preferably in different colors.
Speaking of travel: you might be tempted to look for a power-only charging cable, but that’s outside the USB-C spec; any power-only cable is improperly wired by definition and not worth the risk. Better to carry your own charger and never plug your phone into someone else’s USB port.
You could totally sidestep USB-C and just charge your iPhone 15 wirelessly instead.
Apple kicked off a whole new accessory ecosystem with MagSafe when it launched the iPhone 12. It uses magnets to align a Qi-based charging coil on the back, which opens up fun new charging options like floating iPhone docks. Apple even added a cool StandBy software feature in iOS 17 that turns the iPhone’s screen into a fancy clock with widgets when placed on a MagSafe dock.

If you buy Apple’s MagSafe charging puck, you’ll still need to have a USB-C power adapter capable of at least 20W of charging to make it work. Certified MagSafe options will, at best, charge iPhones at 15W. And non-Apple-blessed “MagSafe-compatible” options will only provide 7.5W of power to iPhones. However, Apple announced iPhone 15 will support the magnet-based Qi2 charging standard, which means it’ll likely open the phone up to faster and cheaper options that probably won’t destroy your iPhone like a bad USB-C cable could.
Wireless charging has its conveniences, but USB-C is still better most of the time.
