The DFRobot UPS HAT is an uninterruptable power supply pHAT designed for the Raspberry Pi Zero.
With the addition of your own 3.7V Lithium battery, the UPS HAT can continue providing power to the Raspberry Pi for a certain period of time when the system is powered off, to avoid system damage and assure a safe shut down.
In addition, the pHAT can be used to supply power for applications requiring mobility such as a Raspberry Pi camera.
