Check Device Runtime Against a Planned Power Outage
A device that runs for four hours on a charge with one spare pack covers eight hours — and no more. Compare the weakest device in the plan with the outage you are preparing for.

FIRST-LOAD
Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the runtime gauge card: your device | runtime hours per charge | spare batteries or packs stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Older batteries often hold less than the label states. After: the runtime gauge card shows the working beside each named row so the reader can change the assumption and inspect the consequence.

one-time step · the free reading above stays complete
Free tier
- one complete runtime gauge card run in the app
- three samples plus unlimited article-demo runs
- unwatermarked result text and an explicit, user-triggered state link
What $4 one-time adds
- print the runtime gauge card with its row workings
- CSV of hours available and row explanations
- last five reading summaries saved in this browser profile
$4 once for repeated filing of the runtime gauge card, not for a better answer. Illustrative time basis: avoiding one five-minute manual reformat per saved reading; no market-price or guaranteed-savings claim.

Boundary and sources
This is a planning estimate from figures you supply and is not clinical or equipment-safety advice. Confirm runtime, backup power and any contingency plan for essential equipment with the device supplier and your care team.
- Method: Runtime times one plus spare packs gives hours available per device. The weakest row becomes the summary because a plan is limited by its shortest runtime; six hours against an eight-hour outage is flagged.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this runtime gauge card, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a runtime gauge card. Return plain rows only: device | runtime hours per charge | spare batteries or packs. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: device | runtime hours per charge | spare batteries or packs. No AI response is executed as code.
