  • ...e: 1) As an outdoor portable power supply, the main board is powered by a lithium battery. The maximum external power supply capacity is: 5.1V. 2.5A. 2) As an indoor UPS power supply mode: the UPS power supply interface is connected to an external 5V power supply, the power supply requires 5V 2A-3A, and the maximum output current can reach 5V 3A..
  • 4+2LED are designed to show the status of battery power, charge or discharge:1) 4 Battery power LEDs: Used to show the current battery voltage and power. 2)The function of the Power LED is to display whether the UPS is supplying power to the Pi, and the LED is on: it means the output is 5V. LED off: Indicates that there is no voltage at the output. 3) Charge charging indicator LED: When the UPS is externally charged via the TYPE-C USB interface, the Charge LED starts to work.
  • The UPS has overcharge and overcurrent protection functions: When the UPS externally outputs about 4A, the UPS will consider the external circuit to be in a short-circuit state and automatically cut off the output. The lithium battery board that comes with the UPS has an overcharge and overdischarge protection board. Prevents the battery from being overcharged and overdischarged when the external circuit is abnormal, thereby reducing the....
