API, OpenAPI and WebMCP documentation

Explanation

Minutes converts into watt-hours with a fixed 15W load. Wh = (minutes / 60) x 15. The direct answer, calculator, common values, and mirror page all stay aligned on that same runtime assumption for typical phone fast-charge and mini displays.

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 Minutes to Watt-hours at 15W load calculated?

Wh = (minutes / 60) x 15. Continuous load is fixed at 15W, so every result uses the same runtime relationship.

What does the fixed 15W load mean?

The calculator assumes a constant 15W power draw, which makes the runtime estimate suitable for typical phone fast-charge and mini displays.

Can I use this Minutes to Watt-hours at 15W load page for runtime planning?

Yes, as a first-pass estimate. The mirror Watt-hours to Minutes at 15W load page handles the inverse direction, but real systems can still vary because of efficiency losses and battery aging.
