A generator is what carries a house through the long outage — the well pump, the 240 V circuits, the fourth day — provided you can place it safely outdoors, store fuel, and have a transfer switch installed before you need it. The realistic failure mode for battery owners is running out with no way to recharge; for generator owners it is discovering the fuel is stale, the gas stations are closed, or the transfer switch was never fitted.", "safetyNote": "Carbon monoxide from a generator is the single most lethal risk in this whole category, and it kills after storms every year: run it outdoors only, far from doors, windows, and vents — never in a garage, breezeway, or basement, and never with the door open \"for ventilation\". Connect to home circuits only through a transfer switch installed by a licensed electrician; backfeeding an outlet can electrocute utility crews. Store fuel safely and check it before storm season.
