It might. While fast charging works on older iPhones with Apple's 18W USB-C charger, for whatever reason, Apple claims that you need at least a 20W charger to fast charge your iPhone 12. While 18W chargers are fast charge-capable according to Apple's support document, in that same document, Apple says that the iPhone 12 requires a 20W or better charger. The iPhone 12 lineup can make use of any standard Qi charger, and there are several great wireless chargers for your new iPhone the choose from. Qi on iPhone 12 continues to support up to 7.5W charging. You can still use USB-A to Lightning cables with the iPhone 12, if you have them. You will just need a charger that has an old-style USB-A port on it. You probably have one of these already. Using USB-A, you can charge your iPhone 12 at a speed of 5 watts. This will charge your iPhone overnight, and is perfectly safe, but it will not be the fastest method. A 5W power adapter is smaller than the 20W equivalent, while a 30W power adapter is bigger and faster than both of those previously mentioned. It doesn't really matter which wattage you go for since they all work, just at different speeds. While the included cable will be fine at first, Apple's cables aren't exactly known for their durability. Instead, you should get one of the many USB-C-to-Lightning cables out there right now. There are too many cables out there made of sturdier materials, like braided nylon, to settle for Apple's default cord. More questions?

A charger so small you won't believe it can be so fast.iMore Does the iPhone 12 support faster charging over USB-C? Additional points to consider include the wattage of the power adapter you buy. The higher the number, the faster your device will charge, but note that the adapter will also be larger. Since iPhone 8, meanwhile, Apple's smartphones have supported fast charging, which allows for a 50% charge in 30 minutes. On older iPhones, you'll need an Apple USB-C-to-Lightning cable and one of these adapters: Apple 18W, 20W, 29W, 30W, 35W, 61W, 67W, 87W, or 96W, or 140W USB-C Power Adapter; or a third-party USB-C power adapter that supports USB Power Delivery (USB-PD). On the iPhone 15 lineup, you'll need a 20W adapter or higher for fast charging, Apple says. Additionally, the newest iPhones are compatible with Qi wireless charging pads. However, Apple's main focus for charging is its built-in, fast charging MagSafe magnetic power connector. MagSafe offers a maximum charging output of 15W when connected to an iPhone with MagSafe, and Apple stresses the need for a 20W charger. You could get Apple's 20W charger to use with MagSafe and call it a day.

Whether you’re looking for something extra long or very strong, these are the best iPhone charging cables

For years, Apple used the term MagSafe to describe its computers' charging cable connectors. Their magnetized tips “snapped” into the magnetized MacBook charging ports—and snapped out if disturbed so as not to bring a Mac laptop crashing to the floor, for example. They disappeared a few years ago as Apple transitioned the MacBook lineup to USB-C charging and data transfer, but returned in the M1 Pro/M1 Max-based MacBooks as "MagSafe 3." Don’t just look at the price. Look at what you want to do now, and what you might want to do next year. For example, an 18W charger will fast charge your iPhone, but it’s not powerful enough to run a MacBook Pro. A more powerful one may be a better option for your future tech arsenal. Using a USB-C cable and USB-C charger will allow the iPhone to charge at faster speeds. Using USB-C, you can charge the iPhone to 50% in about half an hour. The highest wattage the iPhone 12 will use is around 22 watts, so a 20 watt or 30 watt charger will result in the about same charging speed. But basically any USB-C charger will be significantly faster than the old USB-A chargers. Can I use my existing charger and cable with iPhone 12?

Apple will suggest you use its 20W USB-C charger. There are plenty of good third-party chargers like this 2-port charger from Anker, and many others available online. Also new to iPhone 12 this year is MagSafe. MagSafe supports a proprietary inductive charging method that offers up to 15W charging. Is there a better USB-C-to-lightning cable to get than the one Apple ships? For as much as we enjoy the iPhone line of smartphones, we can’t in good conscience say that the official charging cables provided are always guaranteed to last the life cycle of the device itself. Fortunately, there are many companies that make exceptional, and in many cases affordable, replacements to the standard-issue charging cable, with some even being wireless.There’s nothing better than switching on your new iPhone for the first time, safe in the knowledge that you have a brand-new charging cable ready and waiting to provide that essential shot of juice when the battery first begins to run low. On the flip side, no feeling is as crushing as plugging in that same iPhone a few months down the line to a well-worn and splitting cable that chooses that moment to breathe its last. In fact, you may find that the iPhone 12 charges more slowly than your old iPhone when using USB-A. This is because the capacity of the iPhone 12 battery is bigger and therefore charging it to full requires more power. Newer iPhones feature significantly larger batteries and therefore using fast chargers over USB-C is recommended as it will charge to full faster. While it's easy to take a fully cynical view of Apple's environmental stances, the fact of the matter is that the company continues to make these environmentally-friendly moves. But the key here is that they don't have to do it. Nothing is requiring Apple to be more environmentally friendly. Yet it is. It's hard work, and it costs Apple not a little money to do things like go carbon neutral at its facilities. Yes, you can fast-charge your iPhone 12 using the included Lightning-to-USB-C cable and a USB-C power charger. I have an 18W USB-C charger. Will that work for iPhone 12 fast charging? Put simply, MFI Certification (Made for iPhone) is a standardised testing process that many third-party or officially licensed iPhone charging cables must go through before hitting the market, ensuring that they are safe for use. Basically, if you see this symbol on a product, you know that it has been rigorously tested ready to be plugged in for years to come. How can I spot a fake cable?

Those who want to protect their iPhone with a case and make use of MagSafe magnetic charging will need a MagSafe-compatible accessory. Naturally, Apple sells several MagSafe-compatible cases and a magnetic wallet ( no more leather, though). Third parties, like Belkin and Otterbox, have their own MagSafe products, too. iPhone FineWoven Wallet with MagSafe File transfer speeds, however, don’t follow this rule. The Lightning-to-USB cable from Apple moves data at 480Mbits/sec. This figure applies to any cable with a Lightning connector, regardless of what connector sits at the other end – even Lightning-to-USB-C cables are limited by the Lightning connector itself. Since iPhone 5, Apple has shipped its iPhones with a 5W USB power adapter in the box, with the exception of the iPhone 11 Pro andPro Max, which shipped with an 18W USB-C power adapter. (Apple's iPads also ship with 10W or 12W USB or 18W or 20W USB-C power adapters, depending on the model.) So unless you bought your first iPhones after the iPhone 12, you probably have one of them lying around. But our testing, it's been found that the 18W charger, while not as fast as its 20W counterpart, will charge your iPhone to over 50% in half an hour. It's just not as much over 50%.Since iPhone 5, Apple has shipped its iPhones with a 5W USB power adapter in the box, with the exception of the iPhone 11 Pro and Pro Max, which shipped with an 18W USB-C power adapter.
