Modeling Portable Power Station Runtime: Why Watt-Hours Watts Fails on Real Loads

A common shortcut for estimating portable power station runtime is dividing nominal battery capacity (Wh) by appliance wattage (W). For example, pairing a 1,152 Wh station with a 40 W load gives a naive estimate of 28.8 hours. In practice, three physical factors reduce delivered runtime—especially on low-wattage AC loads: Depth of Discharge (DoD)...
