Blackout Math — a reliable energy assistant for real power outages
When electricity is unstable, guesses are expensive.
Blackout Math is not just a calculator — it’s a practical decision-making tool that helps you choose the right battery or power station and understand exactly how long your home can stay powered in real conditions.
Built for real scenarios, not ideal numbers.
Choose the right battery with confidence
Configure battery type, capacity, and voltage — and Blackout Math will:
- calculate usable energy in Wh and kWh
- account for safe depth of discharge for each battery chemistry
- show realistic operating limits
- help you avoid inefficient or harmful usage
No overestimation. No dangerous assumptions.
Know how long your appliances will really work
Add any household devices — lights, laptops, routers, refrigerators, boilers, or heaters.
Specify power, quantity, and daily usage, and the app will instantly:
- calculate real energy consumption
- show each device’s impact on total load
- determine actual runtime — not theoretical values
You’ll know exactly when power runs out.
Realistic charging time — without guesswork
Blackout Math considers battery chemistry and charging limits to provide:
- accurate charging time estimates
- warnings about unsafe charging currents
- charging power based on voltage × amperage
- state-of-charge calculations from any starting level
No unrealistic “from 0 to 100%” promises.
Complex energy concepts, explained simply
The app clearly explains:
- what DoD is and why it matters
- how inverter efficiency affects runtime
- why usable energy is always lower than nominal
- how to choose a battery that fits your real needs
No engineering background required.
Designed for clarity and speed
Clean form-based inputs, instant calculations, intuitive sliders, and light & dark themes — everything is built for fast, stress-free use.
Perfect for:
- choosing portable power stations (EcoFlow, Bluetti, Anker)
- estimating backup time for apartments and houses
- planning for blackouts
- selecting batteries for solar systems
- analyzing and optimizing home energy consumption
Blackout Math is built for real conditions.
It helps you make confident decisions, avoid costly mistakes, and always know:
- how long your power will last
- when devices will shut down
- which battery truly fits your needs
Less guessing. More certainty. Better energy decisions.
