Backup Power
Power Station or Gas Generator? An Honest Comparison
Key takeaways
Compare the limits, fuel, operating rules and power needs.
- Portable gas generators produce carbon monoxide. CPSC says to use them outside only, at least 20 feet from the home, with the exhaust pointed away.
- Battery power stations make no exhaust, but their capacity is limited and they must be recharged.
- Size either option from the appliances you actually need to run, using their labels.
- Never plug a generator into a wall outlet. Connecting to home wiring needs a transfer switch installed by a licensed electrician.
What this guide covers
Compare the limits, fuel, operating rules and power needs. The details depend on your home, equipment and the information on your own bill or appliance label.
How the two compare
| Battery power station | Portable gas generator | |
|---|---|---|
| Where it can run | Indoors, following the manual | Outdoors only, 20+ feet away |
| Runtime | Limited by battery size | As long as fuel is available |
| Refueling | Wall, car or solar charging | Stored fuel |
| Noise and fumes | Quiet, no exhaust | Loud, carbon monoxide |
Which fits your home?
A power station is often enough for a refrigerator, phones, lights and a modem through short outages. Longer or more frequent outages, or larger loads such as well pumps, may call for a generator or a professionally installed system.
Carbon monoxide safety
Install battery-operated or battery-backup CO alarms. Never run a generator in a home, garage, basement or crawlspace, even with doors and windows open. CDC lists headache, dizziness, weakness, nausea and confusion as common symptoms of CO poisoning.
