Fast charge increases voltage and decreases current
Usually referred to as fast charge, the principle is to increase the charging voltage. The phone will show that it is fast charging, and the main function is the charging head.
Advantages: Because the current is low, the compatibility is strong, and the data line is not too high, so the cost is low.
Disadvantages: Increasing the voltage will generate higher heat, causing the phone to heat up and affecting battery life.
Note: Fast charging does not have high requirements for mobile phone chargers and data cables, and chargers that support flash charging technology can be used, which will not cause substantial harm to mobile phone batteries.
Flash charge reduces voltage and increases current
Many brands say flash charge, the principle is to increase the charging current. In the case of constant voltage, the higher the current, the less time the battery will be fully charged.
Advantages: When charging with flash charge, heat will be transferred to the charging head, so it is safer.
Disadvantages: Due to the large current, special charging head and data cable are required, so the cost is higher and the price is higher.
Note: Flash charging technology requires a customized charger and is incompatible with other chargers. If you use an incompatible charger, it will not only cause harm to the battery, but also greatly reduce the charging efficiency.
Flash charge does not damage the battery.
Flash charge refers to the rapid charging of the mobile phone without increasing the voltage or current. Fast charge is to increase the input voltage of the charger to achieve fast charging of the mobile phone, and the charging voltage of the mobile phone is 5V. High voltage constant current mode: The charging process of the general mobile phone is to first reduce the 220V voltage to 5V charger voltage, 5V charger voltage and then to 4.2V battery voltage. During the whole charging process, if the voltage is increased, heat energy is generated, so when charging, the charger will heat up, and the phone will heat up. And the greater the power consumption, the greater the damage to the battery.
VOOC flash charging technology belongs to low voltage and high current fast charging, and other fast charging belongs to high voltage and low current fast charging. High voltage charging, mobile phone temperature is relatively high, relatively speaking, VOOC flash charging security is very high.
