Calculators
Estimate runtime, find the right battery size, and plan for outages using real-world efficiency assumptions.
What Size Do I Need?
Pick the devices you want to run and get the exact station size — minimum inverter watts, surge (startup) watts, and battery capacity — plus stations that clear all three.
Runtime Calculator
How long will a power station run your devices? Select multiple devices, enter your battery size, and get an instant estimate with real-world efficiency losses.
Fridge Backup Calculator
How long can you keep your fridge running during a power outage? Accounts for compressor duty cycles, startup surge, and different fridge types.
CPAP Runtime Calculator
How many nights can your power station run your CPAP? Accounts for humidifier settings, pressure levels, and AC vs DC mode.
Solar Recharge Calculator
How fast can you solar-charge your power station? Accounts for panel size, sun conditions, and station input limits.
