Check the Device, Charger, and Backup You Plan to Bring
The main device can be ready while the charger, spare battery, or preferred setting is not.
Inventory assistive devices and accessories by owner, packed state, review date, and safe storage location.
What changes the result: the devices and accessories you rely on and the settings you want to verify.
Privacy: Calculations run in this browser tab. This tool has no input-upload, account, or AI endpoint. The site may send a page-view signal to Cloudflare; this tool does not add form entries to that signal. A draft is stored only if you choose “Save draft on this device”; that browser storage is not encrypted. Avoid identifiers or sensitive details, and delete saved drafts when finished.
Your entries
The starting rows below are fictional examples. Edit them, replace them with non-sensitive labels and values, or load the sample again. The result is not advice or a source verification.
Amount fields use the same units you enter; the app does not choose a currency. Dates are the ones you provide. Up to 100 rows per run.
Calculated output
What the calculation does
For each item, calculate max(0, target minus available quantity). The total is the sum of those user-defined gaps. A quantity target is not a safety, medical, or purchase recommendation.
Question to keep open: Should the kit be packed for the most common day or for the disruption that would be hardest to recover from?
Boundary: The checklist cannot verify device function, repair needs, or safety. Follow manufacturer instructions and the device user's own support plan.
Copy includes the headline, aggregate metrics, and boundary—not the row-by-row input. The CSV contains entries you choose to download. Review it before sharing.
