You can't. 1. Because the official requirement of iPhone XR is to use the 18-watt 5v2.6a charger of Apple's Lightning interface for fast charging, Xiaomi's 5V2.1A charger cannot provide enough power and current to meet the fast charging needs of iPhone XR. 2. In addition, the use of non-official certified chargers may have compatibility and security issues, which may lead to abnormal conditions during the charging process or even damage to the device. Therefore, from the consideration of charging effect and security, it is not recommended to use millet 5V2.1A charger to fast charge iPhone XR.
It is recommended to use a charger that meets official requirements to ensure the best charging results and device safety.
The reply is as follows: 1. You can use the Mi 18 watt 5V2.1A fast charge to charge the iPhone XR.
2. Cause: iPhone XR supports fast charge technology and matches the output parameters of Mi 18 watt 5V2.1A fast charge. 3. Fast charge is a charging technology that can charge devices faster by providing higher current and power. However, although the iPhone XR supports fast charge, for charging safety and optimal performance, it is recommended to use an original Apple Fast charge adapter or an Apple-certified charger. Of course, the Mi 18 watt 5V2.1A fast charge can also provide reliable charging for the iPhone XR, but there may be a slight difference in charging speed.
You can use the iPhone x, which supports up to 18w fast charge.
