    Q21: How long will AC500 run my device? A: The running time of the AC500 power station for a specific device can be calculated using the following formula: Running time = battery capacity x DoD x η ÷ device rated power Where DoD refers to Depth of Discharge and η is the local inverter efficiency. For the AC500, both DoD and η are assumed to be 90%. As an example, if you run a 1,000W microwave oven with an AC500 + B300S combination, the running time will be approximately: 3,072Wh x 90% x 90% ÷ 1,000W ≈ 2.5 hours Please note: 1) This formula is not suitable for inductive loads with compressors, such as refrigerators or air conditioners. 2) The provided data is for reference only.
