How Much Battery Capacity Gets You Through an Outage
Resilience and safety · PROBLEM-FIRST
A portable power station stores electricity in a rechargeable battery and releases it through an inverter, so it produces no exhaust and no fuel is burned, which is why it can run safely indoors or on a covered porch. A gas generator burns fuel continuously and can produce far more power for far longer, but it must run outdoors, away from windows and doors, because of carbon monoxide risk, and it needs a fuel supply on hand. A power station fits lights, a fridge, a sump pump, phone charging, and a home router through an outage measured in hours; a generator fits a whole-house or multi-day need. Sizing a power station correctly means adding up the wattage of what actually needs to keep running, a fridge typically cycles rather than drawing power constantly, a sump pump draws more only when it runs, phone chargers and a router draw very little, against the unit's rated AC output, then checking the stored capacity against how many hours those loads need to run. None of the three units compared here are sized to run a central air conditioner or an electric water heater. This section explains that sizing question before naming any product.

Who this isn't for
This is not for a whole-house or multi-day power need; none of the three units compared here are sized to run high-draw appliances like a central air conditioner or an electric water heater, and that job needs a gas generator instead, run outdoors and away from windows and doors because of carbon monoxide risk. It is also not for anyone who has not first added up their real loads; picking a unit by price or brand alone, without checking stored Wh capacity against what actually needs to run and for how long, risks a unit that runs out well before the power comes back.
