Plan daily electricity use and compare outage loads with your battery.
About Watt Garden
Estimate daily energy use and cost from device wattage and hours, then compare a planned outage window with battery capacity you enter. Add or edit devices, try a flexible-load scenario, and export CSV or a printable PDF. This standalone tool makes no network requests; values are user-entered rough estimates, not electrical safety advice.
