The iPhoneSE2 supports fast charging, up to 18W wired fast charging and 7.5W wireless charging.
< br >
In wired fast charge mode, the iPhoneSE2 can be charged up to 50% in 30 minutes. It should be noted that the iPhoneSE2 fast charge mode needs to be used with a power adapter with 18W or more power, but its standard is a 5W original charging device, which needs to purchase a separate fast charge source adapter.
Fast charging is not supported. At present, all mobile phone models and devices of the iPhone series do not support a fast charge of the mobile phone system, because the manufacturer does not give the device the function of fast charge. Fast charge is not available and does not support fast charge.
