API, OpenAPI and WebMCP documentation

Explanation

Kilowatt-hours converts into hours with a fixed 20W load. hours = (kWh x 1000) / 20. The direct answer, calculator, common values, and mirror page all stay aligned on that same runtime assumption for tablet charging and light laptop idle.

Method & Profile Basis

Profile basis: output depends on the selected page-specific profile and keeps the same assumptions in both directions.
Profile reference: load profile.
Consistency rule: calculator output and table values use the same profile assumptions in both directions.

Questions & answers

Frequently Asked Questions

How is Kilowatt-hours to Hours at 20W load calculated?

hours = (kWh x 1000) / 20. Continuous load is fixed at 20W, so every result uses the same runtime relationship.

What does the fixed 20W load mean?

The calculator assumes a constant 20W power draw, which makes the runtime estimate suitable for tablet charging and light laptop idle.

Can I use this Kilowatt-hours to Hours at 20W load page for runtime planning?

Yes, as a first-pass estimate. The mirror Hours to Kilowatt-hours at 20W load page handles the inverse direction, but real systems can still vary because of efficiency losses and battery aging.
