Apple x is to support the fast charging function, but the original charger is still an ordinary 5W charger, want to achieve fast charging to buy their own fast charging appliances, then Apple x support how much w fast charging? Here is the relevant information for you.
How many w fast charges does Apple x support
Support is 18W fast charge, according to the official introduction of 30 minutes can be charged up to 50% power, need to use 18W or more power adapter (need to buy separately).
The iPhoneX Fast Charge uses the USB PD charging protocol, and Apple is one of the members of the charging protocol alliance. At this stage, Apple's official chargers that can be used by the iPhoneX to support fast charging have five USB-C interfaces: Apple 18W, 29W, 30W, 61W and 87W.
We may be more curious, Apple mobile phone only supports the maximum 18W charging power, then those charging head after 29W to charge iPhoneX will not burn the phone? You don't have to worry, the USB PD protocol is that the charging head and the mobile phone (charged device) can shake hands, that is, when you connect an Apple original 87W(Apple Macbook Pro's original USB-C charger) to the iPhoneX for charging, the charging head will first communicate with the phone. The iPhoneX will then tell it that I am only a phone, and the maximum current is only 18W, so even if you use an 87W charger, it will never charge the iPhoneX more than 18W.
A: The Apple x can be charged with 40w fast, but it is not recommended.
Because the iPhonex supports the highest power 18w fast charge, according to official data, you can quickly charge to 50% in 30 minutes, which has been very fast, there is no need to use 40w fast charge, one is that Apple x only supports 18w fast charge, charging power can only be charged by 18w, and the second is that if you use 40w fast charge, not only harm the battery health, Charging speed will not be much faster than 18w.
Thank you for reading, Apple x is not able to use 40w fast charge, the official maximum support 30w fast charge, 40w is not supported.
