SwitchExplanation
Formula: Minutes = Watt-hours × 20. Why: runtime is energy divided by power, so this route fixes load at 3W and applies the direct runtime = energy / power relationship.
Watt-hours (Wh): an energy unit commonly used for batteries, power banks, and small backup systems.
Minutes (min): a shorter runtime duration unit useful for compact devices, peak-load windows, and quick planning checks.
This route is useful when estimating how long a battery will run at a fixed 3W load for laptops, UPS systems, portable gear, and backup planning.
This page is purely multiplicative because load power is fixed at 3W, so the runtime-to-energy relationship stays constant for this route.

Frequently Asked Questions
How is Watt-hours to Minutes at 3W load calculated?
minutes = (Wh / 3) x 60. This page fixes continuous load at 3W, so every result uses the same runtime relationship.
What does the fixed 3W load mean on this page?
It means the calculator assumes a constant 3W power draw, which makes this route suitable for standby electronics and light network gear.
Can I use this Watt-hours to Minutes at 3W load page for runtime planning?
Yes, as a first-pass estimate. The mirror Minutes to Watt-hours at 3W load page handles the inverse direction, but real systems can still vary because of efficiency losses and battery aging.
