The total charge amount of the mobile phone charged within 30 minutes is greater than or equal to 60% of the rated capacity of the battery.
China's first mobile phone fast charging standard has been released, the standard for fast charging is: from the initial charging state, the total charging amount of the mobile phone within 30 minutes is greater than or equal to 60% of the rated capacity of the battery, or 30 minutes after the start of charging, during which the average current entering the mobile phone battery is not less than 3A (A is the current unit ampere).
Fast charging products, mainly including charging cable and charging plug two parts, according to different brands, the price is different, the sales of fast charging products are mainly 5V2A and 9V2A, consumers can choose according to their mobile phones.

Compare fast charge with slow charge
For example, one No. 5 nickel-metal hydride battery has a capacity of 1200mAH, while the other has a capacity of 1600mAH. The capacity of a battery is called 1C. When charging, when the charging current is less than 0.1C, it is called trickle charging. Trickle charging can charge the battery very fully without harming the battery life, but the time taken to charge with trickle is too long, so it is rarely used alone, but in combination with other charging methods.
When the charging current is between 0.1C-0.2C, it is called slow charging. Charging current greater than 0.2C, less than 0.8C is fast charging. When the charging current is greater than 0.8C, it is called ultra-high-speed charging.
