Frequently Asked Questions

How many watt-hours do I need for home backup?
Runtime depends on the measured load, inverter efficiency, temperature, battery age, and recharge path. Size from the actual essential loads and required runtime; do not treat a generic watt-hour range as a guarantee, especially for medical equipment or whole-home use.
Can a portable power station power my whole house?
Do not infer whole-house capability from battery capacity alone. Panel-connected backup requires compatible equipment, load planning, correct installation, and compliance with manufacturer and local electrical guidance. Compare the essential circuits, runtime target, recharge path, and transfer equipment for the exact system.
Is a portable power station better than a generator for home backup?
Portable power stations produce no combustion fumes at the point of use and may be suitable indoors when the manufacturer permits it. Generators require outdoor operation and ventilation because of exhaust and carbon-monoxide risk. Choose based on the required load, runtime, recharge path, installation, and safety guidance rather than assuming one is better for every home.
