Power stations vs. gas generators

A portable power station is a big rechargeable battery with outlets. It’s silent, has no fumes, and is safe to use indoors. A gas generator produces more power for longer, but it must run outside, at least 20 feet from doors and windows, because of carbon monoxide.

For most households, a power station is the easier, safer starting point.

How to read the numbers

  • Wh (watt-hours) is the size of the tank. More Wh means it runs things longer.
  • W (watts) is how much it can power at once. Check that it covers your hungriest device.

A rough guide: a 300Wh station will recharge a phone many times over, or run a 10W LED lamp for around a day. Check the wattage label on anything you plan to plug in, especially medical devices like a CPAP.

Which size do you need?

  • Phones, lights, radio, Wi-Fi router: 250 to 500Wh
  • Add a laptop, fan or CPAP for a night or two: 500 to 1,000Wh
  • Fridge, sump pump, well pump: 2,000Wh and up, with high output

Keep it ready

Charge your station fully, then top it up every 3 months. Store batteries in a cool, dry place, and test everything once a season so you’re not discovering a dead battery during a storm.
