⚡ Runtime Calculator
Enter your devices and their wattage. We estimate how long any power station will run them — accounting for inverter losses and usable battery depth.
Open calculator →🔋 What Size Do I Need?
Shopping for a power station? Enter what you want to run and for how long — we work out the capacity (Wh) and output (W) to buy, with honest headroom so you don’t get one too small.
Open size calculator →☀️ Solar charge time
How long will your solar panels take to refill your power station? Uses real-world panel output (not the sticker rating) and peak sun hours, so the estimate is honest.
Open charge calculator →☀️ Solar & cable compatibility
Voltage windows, MC4 / XT60 / Anderson adapters, and which third-party panels actually pair with which power station — worked out brand by brand.
