Single power on/off switch: The battery will no longer phantom drain when the power is off, which means the device can be completely powered off. Advanced battery management IC Matte screen: This matte screen can help you see the content on the screen more clearly in sunny outdoor environments. GPIO Port: The generation H2M adds a GPIO port, allowing users to create their own add-ons for the H2M, similar to the Flipper Zero. This is a major step forward and a feature not available in previous versions of Portapack. Improved charging speed: The H2M has improved charging quality and speed.
