The charging speed of mobile phones is generally affected by three aspects
I. Whether the output power of the power adapter (i.e. the charger) can meet the needs of the mobile phone. Mobile phone according to the different battery capacity, the charging current requirements are also different, generally 05C-0.8C, for example, 0.5C of 2000MAH battery, is the current 1A, 0.8C is 1.6A, his charging current is between 1A and 1.6A, mobile phone will generally set this value, 1A or 2A, It is also to meet the output standards of the power adapter (charger) on the market. It can be simply understood that the charging current of the battery with a capacity less than 2500MAH is generally 1A, and the charging current of the battery with a capacity greater than 2500MAH is 2A.
The output current of the selected power adapter should be equal to or greater than the charging current of the phone. There is a common misunderstanding here, that is, some people think that the high-power charger will burn the phone or overcharge the battery, in fact, the output current of the power adapter is its maximum output, the actual input current when charging the phone is determined by the control circuit of the phone, not by the power adapter. Burning the phone or overcharging the battery is caused by the output voltage of the poor quality power adapter exceeding 5.2V and a long charging time, which has nothing to do with high power. It is recommended that when choosing a power adapter, choose a power that is larger than your phone's requirements, so that for the power adapter, there is no full load operation, and it can ensure the stable output of the current.
2. Data line pressure drop is qualified. The data line is connected to the charger and the mobile phone, because the data line has resistance, so there will be a voltage drop on the data line, if the resistance is too large, it will lead to a large amount of power loss on the data line. Affecting the charging speed, the copper wire in some roadside data lines on the market is very thin (the finer the resistance value is greater), and even not pure copper (such as copper-clad aluminum), the resistance value is very large, which may cause you to charge slowly, or even not charge.
3. Whether the charging mode is limited. If you use the wrong way to charge may also be limited charging current, resulting in the power of your power adapter can not play a role. There are two common current limiting, one is the data transmission mode charging, the current will be limited to 0.5A below, commonly used in the computer USB port to charge the phone office crowd, to solve this problem is the easiest way to replace the data line with a special charging line.
Do not affect
The plug-in board only provides working voltage for the mobile phone charger, and does not affect the working efficiency of the charger, nor does it reduce the charging speed.

2 The charging speed of the mobile phone depends on the mobile phone support related fast charge protocol parameters are related to the charger output current parameters, the faster the current output of the mobile phone charger, the faster the charging speed, the higher the mobile phone battery support fast charge protocol parameters, the faster the charging speed, so the plug bar will not affect the charging speed
Charge fast and slow with charger plug, charging cable
It doesn't matter. It is related to the current size of the design of the charger itself. In theory, the higher the current of the charger, the faster the charge.
There are many types of nokia chargers
The charging current is also different. Therefore, the charging time of different mobile phones will also be different.
The speed of charging is related to the output voltage and output current of the charger, similarly, a good data cable is also influential, which can reduce the loss of charging and make charging faster
