On a full charge, with no other loads. A space heater uses 6.0–18.0 kWh a day and draws 1,500 W on high, ~750 W on low; about 85% of the battery reaches the outlet after the inverter's losses. Electric resistance heat is the hungriest thing you can run on batteries. It drains a power station in about an hour.
Tip: For outages, heat with wood or propane and save batteries for the fridge and lights.
