About Blackout Math: Home Energy
Blackout Math — your reliable energy assistant during outages and unstable electricity.
This is more than just a calculator.
It’s a smart tool that precisely determines which power station or battery you need to keep your apartment, house, or office running—based on real scenarios.
Accurate battery selection
Set the battery type, capacity, and voltage — and Blackout Math will automatically:
• calculate available energy in Wh and kWh
• consider the optimal depth of discharge for each battery chemistry
• suggest safe operating parameters
• help you avoid inefficient or harmful usage modes
Appliances and their power consumption
Add any household devices — lighting, laptops, refrigerators, boilers, routers, or water heaters.
You specify the power, quantity, and daily runtime, and the app instantly:
• determines the actual energy consumption
• shows each device’s contribution to total load
• calculates how many hours your battery can really power your home appliances
Precise charging time calculation
Blackout Math accounts for the characteristics of every battery type and provides:
• realistic charging time
• warnings about unsafe charging currents
• charging power based on voltage × amperage
• SOC calculation from any starting level
Everything is explained clearly, even for users who have never dealt with energy systems before.
Smart explanations of complex concepts
The app explains in simple words:
• what DoD is and why it matters
• how inverter efficiency works and how it affects runtime
• why usable energy is always lower than the nominal one
• how to choose a battery that matches your real conditions
Thoughtful interface
A structured form-based layout, instant calculations, clean sliders, and light & dark themes — designed for fast, intuitive interaction.
Perfect for:
• choosing a portable power station (EcoFlow, Bluetti, Anker)
• estimating autonomy for an apartment or cottage
• planning backup power during blackouts
• selecting the right battery for a solar system
• analyzing load and optimizing home energy consumption
Blackout Math is built for real Ukrainian conditions — helping you confidently manage your home energy.
Always know when your devices will shut down, how long your station will last, and which battery fits your needs best.
