Runtime calculator
Estimate hours from Wh, watts, efficiency, reserve, battery health, temperature, and duty cycle.
Appliance wattage library
Search source-backed watts, duty cycle, source type, confidence, and scenario links before entering a load.
Size finder
Choose a practical source-backed station class for outage, CPAP, Starlink, camping, or remote work.
Solar charge calculator
Estimate recharge time from panel watts, sun hours, station input limits, and derating.
Battery charging time calculator
Estimate AC, vehicle, or custom charging time from a known accepted input, state-of-charge gap, efficiency, and taper.
Surge checker
Check running watts and startup surge before trusting a station with compressors or tools.
Focused Tools
Use these when a generic runtime estimate is not enough for the device or setup.
Battery capacity converter
Convert Wh, mAh, Ah, and volts before using a battery label in runtime math.
Battery runtime calculator
Estimate runtime for batteries and packs when you know watt-hours, volts, load watts, and reserve assumptions.
mAh to Wh calculator
Convert milliamp-hour power bank labels into watt-hours with the voltage included.
Wh to Ah calculator
Convert watt-hours into amp-hours for 12 V, 24 V, 48 V, or a custom voltage.
Starlink Mini calculator
Plan Starlink Mini runtime across USB-C PD, DC, AC power stations, power banks, and solar offset.
Starlink Mini kit planner
Check battery, cable, USB-C PD or DC path, reserve, solar offset, and matching source-backed station records.
CPAP runtime calculator
Estimate overnight CPAP runtime with humidifier, heated tube, inverter, and reserve assumptions visible.
CPAP battery backup guide
Plan CPAP backup nights, humidifier settings, AC/DC path, reserve, and manufacturer-guidance checks.
RV power calculator
Bundle lights, router, fridge, fan, laptop, CPAP, and solar planning into one RV load path.
