Product description

  • Two working modes divided into outdoor portable power supply and indoor UPS power supply. As an outdoor portable power supply, the main board is only powered by lithium batteries. The maximum external power supply capacity is 5.1V 2.5A. As an indoor UPS power supply plug the Micro-USB into the ordinary 5V 2A power adapter, and the external output USB-A interface can output up to 5.1V 3A.
  • 4 + 2LED charging and discharging, battery level display. The main board integrates overcurrent and overdischarge protection.
  • The external output port has a resettable fuse to prevent burnout for Raspberry Pi due to external short circuits.
  • When the total current of the 2 USB output ports reaches 3A, the resettable fuse will blow. When the external port is unloaded, the 5V output will automatically resume.
  • PMU over-discharge protection When the lithium battery voltage is lower than 2.8V, PMU judges that the battery has been over-discharged and automatically cuts off the 5V output.
