Estimated Runtime
Device runtime depends on battery capacity, device wattage, conversion efficiency, temperature, and the number of connected devices.
The following formula can be used for a rough estimate:
Total Watt-Hours × 0.90 Depth of Discharge × 0.90 Conversion Rate ÷ Device Wattage = Estimated Runtime
For example, running a 1,000W device from one fully charged 2,048Wh battery:
2,048Wh × 0.90 × 0.90 ÷ 1,000W = Approximately 1.6 hours
Actual runtime may vary. Additional energy is also consumed whenever an output port is active.
