• Q11: How long can it run my device?

  Running time = Battery capacity × DoD × η ÷ Device rated power
  DoD refers to Depth of Discharge and η is local inverter efficiency.
  For B300s, both DoD and η are 90%. If you run a 100W light bulb with it, the running time will be:
  3,072Wh × 90% × 90% ÷ 100W ≈ 25hrs
  Note: The above data is for reference ONLY.
