FAQ
Q1. What 18650 battery is recommended?
A: 18650 battery dimension
Q2. What is the power output for each usb port?
A: It is 5V, all ports share 4A, not limited to 500mA.
Q3. Is there any way I can check from the raspberry pi if it's connected to the power or the battery from the UPS?
A: When connected to the power supply to X306, the power supply supplies power to the Raspberry Pi; remove the power supply, it is powered by the battery.
