What is fast charging?

Fast charging is to shorten the time required for charging by increasing the charging power P. There are three ways to increase the power, which is to increase the voltage, increase the current, and increase the voltage and current at the same time. The fast charge USB cable is just the data line that supports fast charge. The fast charge charger needs to match the number of currents to the phone. If it is too large or too small, it will hurt the phone.

Expanding information:

1. When the phone is charging, it is the phone itself, not the charger, that determines the charging current. In general, the phone automatically detects the load capacity of the charger and determines the amount of current input based on its own power.

2. For example, if you charge the 9V 1.67A Samsung S7 Edge with the iphone 5V 1A charger, the charger will charge at the highest load. The charging current reaches 1.08A during the test. It is easy to heat up after a long time. Burn out the charger.

3. The so-called fast charge and slow charge is a concept, using current as the standard (that is, a few A), the standard charge is lower than the discharge current is standard charge; equal to or higher than the discharge current can be called fast charge. Fast charging will increase the temperature of the battery and is harmful to the battery. However, considering the current life of charging and discharging the rechargeable battery, this is basically negligible.
