Generators vs. Power Stations: Which Backup Power Do You Need?
For a short outage, a battery power station is quiet, safe indoors, and enough for phones, lights, and a CPAP. For outages that last days or weeks, you want a fuel generator. Many households end up with both.
Below we compare the generators and power stations on our list, explain how to size one, and cover the safety rules that prevent the most common storm deaths.

| Honda EU2200i Inverter Generator | Gas | 2,200W | Quiet, reliable essentials; pair two for more power |
| EcoFlow DELTA 2 Portable Power Station | Battery + solar | 1,024Wh, 1,800W | Silent indoor power for a CPAP, fridge, or home office |
| Jackery Explorer 1000 v2 Power Station + Carrying Case | Battery + solar | 1,070Wh, 1,500W | Indoor power that recharges from solar panels |
| EcoFlow RIVER 3 Portable Power Station | Battery | 245Wh | Phones, lights, and short outages |
Generator or power station?
- Choose a generator if outages in your area last days or weeks, or you need to run a fridge, freezer, well pump, or space heater for long stretches.
- Choose a power station if you need silent power indoors (apartments, CPAP machines, home offices), or outages are usually short.
- Choose both if you can. Run the generator a few hours a day to recharge the power station, and use the battery overnight while the generator rests.
How to size a generator
- List what you need to run at the same time: refrigerator, lights, phone chargers, a fan or space heater, medical equipment.
- Check each appliance's label for its watts. Motors (refrigerators, well pumps, sump pumps) briefly draw several times their running watts when they start.
- Add up the running watts and make sure the largest starting surge fits under the generator's peak rating.
- Leave headroom. Generators run longer and quieter well below their maximum.
Safety: the rules that save lives
Carbon monoxide from generators kills people after nearly every major storm. The CDC's guidance is clear:
- Run generators outside only, at least 20 feet from doors, windows, and vents, with the exhaust pointed away from the house.
- Never run one in a garage, basement, shed, or porch, even with the door open.
- Put battery-powered CO alarms near every sleeping area.
- Never plug a generator into a wall outlet ("backfeeding"). It can electrocute utility workers. Use extension cords or a transfer switch installed by a licensed electrician.

FAQ
What size generator do I need for a refrigerator?
Most home refrigerators run comfortably on a 2,000–2,500W inverter generator. Check your fridge's label, and remember the compressor's brief startup surge. For a fridge plus a freezer, lights, and more, look at 4,000W and up.
Can I run a generator in my garage with the door open?
No. Carbon monoxide builds up quickly in garages even with the door open. Run generators outside, at least 20 feet from the home, with exhaust pointed away.
Is a power station better than a generator?
For indoor use and short outages, yes: it's silent and makes no exhaust. For multi-day outages, a generator is better, because it can keep producing power as long as you have fuel.
