What to know

A pellet stove burns wood pellets, but it needs electricity to feed them and to move air, so it stops when the grid does. The class in the data runs at about 180 W and needs about 425 W at start. Nearly every station in the data clears those power checks; the battery decides how long the heat lasts.

Running all day, the stove uses 4,320 Wh, about 5,082 Wh of rated capacity at 85% efficiency. 2 of the 54 stations last the full day. The closest fit is the EcoFlow DELTA Pro Ultra (6,144 Wh). 51 more run it for part of the day; the longest of them, the Jackery Explorer 5000 Plus, lasts 23.8 h.

For one 8 hour night, 28 stations are enough. The smallest is the ALLPOWERS R2500 V2 (1,920 Wh), with about 9.1 h. The stove's own label or manual gives the watts for your model, and the calculator takes that figure.

Follow the stove maker's instructions for a power cut, and plug the stove straight into the station rather than through a long extension cord. A gas furnace blower and a space heater are the other winter setups worked out here.
