Improvements of Portapack H4:
* Single power on/off switch: When powered off, the battery will no longer phantom drain, meaning the device can be completely powered off.
* Advanced battery management IC and battery display: The screen can display the battery level, including percentage, voltage, and current/draw. It is easier to check the battery level.
* Matte screen: This matte screen helps you see the content of the screen more clearly in sunny outdoor environments.
* GPIO port: Since this feature is rarely used by users, it is built into the mainboard. If you need to use the GPIO port, the H4 cover must be opened.
* Improved charging speeds: The H4 improves both the charging quality and speed.
* Microphone on/off switch: It allows you to turn the microphone on or off.
