Apple finally introduced the fast charging feature in iPhone 8, iPhone 8 Plus and iPhone X, a feature that has been available on Android smartphones for quite some time.
Unfortunately, though you need to spend an arm and a leg if you want to take advantage of the fast-charging as the 5W adapter that is included with the iPhone 8 and iPhone 8 Plus does not support the feature.
You can also use this cable with your Apple 29W, 61W, or 87W usb-c Power Adapter to charge your iOS device, and even take advantage of the fast-charging feature on iPad Pro, iPhone 8, iPhone 8 Plus, and iPhone X.
Twitter user Dan Loewenherz carried out some tests to find out how much time it takes to charge his iPhone 8 Plus with the 5W charger that comes with the iPhone 8 Plus, 10W and 12W iPad charger, 29W, 61W and 87W chargers.
The results are quite interesting. As you can see in the graph below, while the 29W, 61W and 87 chargers charge the iPhone 8 and iPhone 8 Plus significantly faster (approx 115-120 minutes) than the 5W iPhone charger (190 minutes), they barely charge faster than the 10W or 12W iPad chargers (135 minutes or 125 minutes respectively).
Fast charging is not about how quickly it can fully charge the device. It is more about how much time it takes to charge the device from 0-50%. As you can see from the chart above, there isn’t much of difference when you consider that parameter as well.
So if you already have the 10W or 12W charger then it is not worth spending $74 on Apple’s 29W USB‑C Power Adapter and Apple’s USB-C to Lightning Cable. Apple’s 61W USB‑C Power Adapter would cost you an additional $20 (total of $94) and Apple’s 87W USB‑C Power Adapter would cost an additional $30 (total of $104).
If you don’t have the iPad charger, then at $19, it is a lot more cost-effective solution as you can use the Lightning cable that ships with the iPhone with the 12W USB Power adapter, and it charges iPhone 8 and iPhone 8 Plus almost as fast as the 29W, 61W, and 87W chargers.
It would have been nice if Apple had shipped the iPhones with the 12W chargers, but as John Gruber of Daring Fireball points out, there are quite a few people who prefer the small 5W charger as it fits into many outlets where the larger ones won’t.
