How to see the parameters of cell phone power adapter
Cell phone power adapter is what we often call charging head, it is a tool to provide power for cell phones, its role is to 220V utility high-voltage pulse through the rectifier, voltage regulator and other circuits, and ultimately converted to 5V low-voltage DC power. Careful observation of friends will find that the cell phone power adapter will have a lot of identification parameters, what do they mean? General cell phone adapter main parameters are.
1, input parameters
Cell phone power adapter input parameters are generally "AC 100V-240V 50/60HZ A format, meaning that can be inserted in the AC 100V-240V, frequency of 50Hz or 60Hz power outlet to use, the maximum current allowed to pass through the working state of XA, generally 0.5-1.5A.
Generally speaking, we do not have to care too much about the input parameters of the power adapter, as long as the regular manufacturers of qualified products have reasonable input indicators.
2, the output parameters output parameters is the core indicators of the cell phone power adapter, it is mainly composed of output voltage and output current, the product of the two is the maximum output power of the adapter, the past is commonly used 5V/1A, that is, 5W output power, with the development of fast charging technology, the cell phone power adapter output parameters are increasingly large and compatible with a number of groups of output standards!
The higher the output power supported by the cell phone power adapter, the shorter the charging time, but the relative volume is also the larger.
