The difference and pros and cons of mobile power software and hardware
The software version is more powerful than the hardware version.
The hardware version is continuously running and the software version is automatic. There is a load to run. Life is longer than hardware.
The hardware version of the LED power display is not accurate enough to achieve the effect of breathing lights and marquees. The software version is intelligent. The software version is more accurate than the hardware version.
The conversion efficiency of the hardware version is generally 75%. The conversion rate for the software version is 85%. That is to say, the mobile power of the same capacity will charge your mobile phone, and the software version will charge more times than the software version. This point is more obvious when the capacity is larger.
The software version has a longer service life, and the software version uses a control IC that can be programmed to control the display of the indicator light and is more intelligent. The hardware version simply uses a simple circuit to control charge and discharge.

Advantages of the software version:
The software version is dual IC control. It is easy to realize synchronous rectification, high efficiency, low heat generation, and flexible function changes, which has become a development trend. Software version optimization is mainly to speed up the main loop. Currently, the main loop is less than 200us. Fast control is achieved by integrating a dedicated comparator. For example, a DC-DC comparison is performed at 5.0 V, and pwm control is turned off unconditionally at 5.5 V.
Input interface: V8 port, micro usb (for Android port, flat port)
Power display: 4 levels of LED lights display power, intelligent automatic shutdown in non-working state.
Charge and discharge protection: The circuit board has a built-in lithium battery protection IC with overvoltage protection, overcurrent protection and undervoltage protection.
Charging input requirements: The best match is the charger above 5V1A, and any other 5V constant voltage power supply can be used as the charging input power.
