Quick answer
A portable power station is a large rechargeable battery: silent, fume-free and safe to use indoors, but limited by its capacity. A generator burns gasoline or propane, can run big appliances for days with refueling, but must run outdoors at least 20 feet from your home. Many households use a power station for essentials and a generator for long outages.
Side-by-side
| Feature | Power station | Generator |
|---|---|---|
| Fuel | Battery (recharge from wall, car or solar) | Gasoline, propane or both |
| Indoor use | Yes, no exhaust | Never, carbon monoxide risk |
| Noise | Nearly silent | Loud |
| Runtime | Limited by capacity | As long as you have fuel |
| Maintenance | Minimal | Oil changes, fuel storage |
How to size a power station
Power stations are rated in watt-hours (Wh), the energy they store, and watts (W), how much they can deliver at once. Add up the running watts of what you want to power at the same time, and make sure the station's output exceeds it.
For a rough runtime estimate: capacity in Wh × 0.85 ÷ device watts = hours. For example, a 1,000Wh station running a 60W CPAP gives about 14 hours. A typical modern refrigerator uses roughly 1 to 2 kWh per day, so a 1,000Wh-class station can keep one running for part of a day. Pairing it with solar panels lets you recharge during the day.
When a generator makes sense
If you want to run a refrigerator, a well pump, a space heater or several rooms for days, a generator delivers far more energy. Inverter generators are quieter and produce cleaner power for electronics. Dual-fuel models can run on propane, which stores longer than gasoline.
Generator safety is not optional
The CDC warns that generator exhaust contains carbon monoxide, which can kill in minutes. Never run a generator inside a home, garage, basement or shed, even with doors open. Keep it more than 20 feet from windows, doors and vents, and install battery-powered CO detectors. Read our generator safety guide before you buy one.
