Product parameters: PD+flash charging+super fast charging+fast charging version Output power: 22.5W USB output: 5V/3A, 9V/2A, 12V/1.5A (Multiple ports output only 5V at the same time) IN input: 5V/2A Type-C output: 5V/3A, 9V/2A, 12V/1.5A (only output is available if PD protocol is supported) Type-C input: 5V/3A, 9V/2A, 12V/1.5A Other functions: long press to turn on the LED light; reverse installation will not burn the motherboard (one positive and one negative will burn the spring) Effective voltage: 3.3V-4.15V (spring has voltage drop) Capacity requirements: The minimum actual capacity of the battery pack cannot be less than 10,000 mAh, otherwise the battery will not be able to discharge power before the power is fully discharged If the mobile phone private protocol is not supported (USB has no fast charging), you can use PD charging (TYPE-C output), and the PD public protocol output is more stable

Fast charging specifications (support protocol ): Integrated SCP22.5W super fast charging output protocol Integrated 22.5W flash charging output protocol Integrated QC4.0+/QC4.0/QC3.0/QC2.0 output fast charging protocol Integrated FCP, AFC input/output fast charging protocol Support PPS, PE2.0, SFCP output fast charging Support PD3.0/2.0, PE1.1 input/output protocol

Note: The product is only allowed to install 21700 flat head batteries, voltage between 3.5V-4.2V, batteries over two years old, and batteries with more than 300 cycles are basically not durable. It is found that the charging can only be used for a few minutes or more than ten minutes intermittently, and the mobile phone cannot be charged half of the time. These are all poor performance problems caused by the battery and the rate is not up to standard. In addition, the product does not support modification and welding. If a battery that does not meet the requirements is used, it is not responsible for after-sales . The motherboard is equipped with an anti-reverse installation chip, so the motherboard will not burn if it is installed in reverse. However, since the spring shrapnel is integrated, the battery is broken, the battery is short-circuited, one positive and one negative, and the series connection will cause the spring to burn. However, after reinstalling correctly, the motherboard can always be used normally and will not burn.
