Although the charging power of domestic Android phones has reached the highest level of 120W, Apple is still quite cautious (it can also be said to be conservative, but in other words, no one can withstand the impact of Samsung's "battery door"), 5W The "little white head" can still be seen everywhere. Last year, the iPhone 11 Pro provided an 18W power adapter, which was more or less an upgrade. In this iPhone 12 series, all four versions have supported 20W.
In fact, although last year's iPhone 11 comes with a 5W charger as standard, it also supports a 20W charging power (to reach a speed of 50% charging in 30 minutes), and even in the actual measurement, it supports a power slightly higher than 20W. This time the iPhone 12 series is the same parameter. So this time we can choose a power adapter with a power of 20W or more to give full play to the charging speed of the iPhone 12 series (although it is not enough, but it is much faster than 5W).
The main thing to watch out for is the charging protocol. There are various fast charging solutions on the market, OPPO's VOOC series, Huawei's Super Charge, etc. are all familiar to everyone. These domestic mobile phone manufacturers have their own solutions with their own mobile phones, and the charging speed is very fast (buy these brands of mobile phones, match them with their own mobile phones) Fast charge is the best). In addition, there are some general solutions such as Qualcomm's QC (Quick Charge, which has recently released QC5) and USB-PD (USB Power Delivery, also known as PD). The main purpose of purchasing third-party chargers is these general solutions.
Apple supports PD (PD fast charging has been supported since the iPhone X generation in September 2017). In Apple's do-it-yourself style, it's rare to be part of a protocol consortium. This is also because of the ubiquity of PD itself and its future. It is promoted by the USB-IF organization that promotes the USB standard, and this status is irreplaceable. At the same time, under the PD protocol, it is also promoting the fast charging protocol compatible with other companies. For example, PD 3.0 supports QC4+, basically rushing towards unification went.
In short, to buy a power adapter for the iPhone 12 series at this stage, you only need to pay attention to: PD fast charging protocol, C port, 20W or more. And if the power is larger (the price is only slightly higher, and the charger is slightly larger), it can also take care of more devices that support the PD protocol, such as iPad and MacBook, to achieve "one charger does everything" .
