Generator or Power Station: Which Fits Your Outages
Both give you electricity when the grid does not. They suit different outages.
The main difference
A generator burns fuel and can run as long as you can supply it, but it has to run outside and gives off carbon monoxide. A power station is a large battery with outlets. It is quiet, has no exhaust, and can sit inside the house, but it only runs until its battery is empty and then needs power to recharge.
Consumer Reports notes that power stations carry no carbon monoxide risk and fit shorter outages, while a similar-size generator will power essentials for longer. Its testing also finds home standby generators the strongest performers, if you can afford one.
Compare by outage length
| Outage | Likely fit |
|---|---|
| A few hours | Power station or even a power bank for phones and lights |
| One to two days | Power station for essentials, or a small inverter generator |
| Three days or more | Portable generator, or a standby generator for the whole house |
| Repeated long outages | Standby generator, installed by licensed professionals |
Compare by what you need to run
| Load | Power station | Portable generator | Standby generator |
|---|---|---|---|
| Phones, lights, router | Easy | Easy | Easy |
| Refrigerator | Yes, for a limited time | Yes | Yes |
| Sump pump | Depends on output and starting watts | Yes | Yes |
| Window air conditioner | Rarely, drains quickly | Yes, with a large unit | Yes |
| Central air or electric heat | No | Only with a very large unit | Yes, if sized for it |
What each one costs to own
- Power station: a higher price per watt-hour, no fuel, low upkeep. Recharge from the wall, a car or solar panels.
- Portable generator: lower price per watt, fuel to buy and store, regular maintenance, and noise.
- Standby generator: the highest total cost and professional installation, with automatic start.
Check current prices at the seller, because they change.
How to decide
- Run your list through the wattage calculator.
- Check your county's outage history on our lookup, when it is live, to see how long outages last where you live.
- Match the biggest load and the longest outage to the table above.
- If you pick a power station, make sure its output and surge ratings cover your largest starting watts.
- If you pick a generator, read the safety section first.
A common answer
Many households end up with both: a power station for phones, lights and a router that never needs fuel or an outdoor setup, and a generator for the days when the outage runs long.
