for Raspberry Pi: Uninterruptible Power Supply UPS HAT for Raspberry Pi 4B/3B+/3B, etc. Supports charging and power output at the same time, with dynamic path management, stable 5V output. Supports 21700 ba-tte--ry ( ba-tte--ry is NOT included). Onboard warning indicators, easy to check if the ba-tte--ry is connected correctly

Uninterruptible Power: It is able to charge the ba-tte--ries and provide power output at the same time from external power supply. Automatically switch over to ba-tte--ries output if external power supply is unavailable, keeps the system running without any trouble

Dynamic Path Management, More Stable Power Supply: Multi ba-tte--ry protection circuits: over charge/discharge protection, over current protection, short circuit protection, more safe and stable

Powering the Raspberry Pi via Pogo Pins: Powering the Raspberry Pi via pogo pins, without using any GPIO resource, compatible with Raspberry Pi 4B / 3B+/3B, etc.

Real time monitoring: Monitoring the ba-tte--ries voltage, current, power, and remaining capacity via I2C. When the voltage dips too low, it is possible to save files properly and then shut down the system by software, to avoid any data loss

Supports ba-tte--ry level display and detecting power connection: Easy to check the ba-tte--ry status in real-time, and automatically shutdown when the ba-tte--ry level is low. Onboard MCU chip for detecting power connection and automatically rebooting the Raspberry Pi

Onboard USB interaces: Adopts USB Type-C interface for charging and the USB Type-A interface for 5V power output, convenient for powering other boards
