First, two different numbers
“1000W” gets used for two different things and the confusion costs people money.
- 1,000W output — how much you can run at once. This decides whether an appliance starts.
- 1,000Wh capacity — how much energy is stored. This decides how long.
A unit can have one without the other. Check both before buying — see what size power station do I need.
What this class runs
| Load | Draw | On ~1,000Wh |
|---|---|---|
| Phones, laptop, lights | 80W | ~11 hours |
| CPAP | 40W | 2–3 nights |
| Starlink Mini | 40W | ~21 hours |
| Full-size fridge | 150W avg | ~6 hours |
| Microwave | 1,000W+ | Minutes, if it starts |
| Space heater | 1,500W | Will not run |
The honest limit. This class is excellent for devices, camping and short outages. It is not enough to carry a fridge through a full day — for that you want 2,000Wh.
Models in this bracket
- EcoFlow Delta 2 — 1,024Wh, 1,800W. Charges far faster than rivals.
- EcoFlow River 3 PlusCheck price on Amazon — smaller but expandable.
- ALLPOWERS — the budget route, still LiFePO4.
- OUPES — more watt-hours per dollar if you will trade brand recognition.
Step up a size: 2000W power stations.
