🔋 How long will a power station run your appliances in an outage?
Quick answer: divide usable battery capacity (rated Wh × ~0.85 inverter efficiency) by the total watts you're running. A 1024Wh station running a refrigerator (~150W average), a box fan (45W), and a Wi-Fi router (15W) lasts roughly 4 hours of continuous draw — longer in practice because fridge compressors cycle on and off.

Estimates use typical average draws and 85% inverter efficiency — a standard assumption for modern portable power stations, whose inverters typically run 80–90% efficient under load. Compressor appliances (fridges, AC) cycle on and off, so real-world fridge-only runtime is often 2–3× longer than continuous-draw math suggests. Always check your appliance's label.
What do these terms mean?
Watt-hour (Wh)
A watt-hour is the amount of energy needed to run a 1-watt load for one hour. A 1024Wh battery can power a 100W device for roughly 10 hours before efficiency losses.
Inverter efficiency
Inverter efficiency is the share of stored DC battery energy that survives conversion to household AC power — typically 80–90% in portable power stations. The lost energy becomes heat.
Duty cycle
Duty cycle is the fraction of time an appliance actually draws power. A refrigerator compressor runs about 30–50% of the time, which is why real fridge runtime beats continuous-draw estimates.
