What size power station do you need?
Add the things you want to run and how many hours a day you'll run them. Every default wattage links to its source. Change any number to match your own nameplate or plug-meter reading.
1. Your loads
| Appliance | Qty | Hours/day | Avg W | Wh/day |
|---|
No loads yet. Add an appliance above, or try a preset: fridge + CPAP + Starlink Mini · outage essentials
2. Assumptions
These defaults are assumptions, not measurements. The 85% inverter figure is a common planning value. Real efficiency drops at very light loads and in the cold. Rated Wh is the battery's nameplate, and not all of it reaches your devices.

*Price on the brand's own US store on the "checked" date. Prices change often. Lifetime kWh = Wh × usable % × rated cycles ÷ 1000. Brands rate cycles to different end points (70% or 80% capacity left), so lifetime figures are rough. Model data & sources. No affiliate links yet. See disclosure.
