Runtime explained
1,000Wh: how many hours is that?
It depends on your average load and how much stored energy reaches the devices.
These are arithmetic examples, not measured runtimes. No specific product is guaranteed to achieve them.
A useful starting calculation
Estimated hours = battery capacity in Wh × assumed usable-energy fraction ÷ average load in W. With a 1,000Wh battery and an assumed 85% usable-energy fraction, that leaves 850Wh for this simplified calculation.
| Assumed load | Estimated runtime |
|---|---|
| 50W | 17 hours |
| 100W | 8.5 hours |
| 250W | 3.4 hours |
| 500W | 1.7 hours |
| 1,000W | 0.85 hours (51 minutes) |
Why your result can differ
The 85% value is a planning assumption. Conversion losses vary; an inverter also consumes energy while it is on. Temperature, battery condition and cutoff settings matter. For a device that cycles, an instantaneous watt reading is not its long-term average.
Before relying on the estimate
Check the power station’s output limits and the appliance’s starting requirements first. Measure your device over a representative period when possible. Then try different usable-energy assumptions in the calculator and leave room for unexpected use.
A runtime calculation alone does not establish that the station and device are compatible.
