Check Ice Packs Against the Hours in Transit
A cool bag packed for a two-hour train is not cover for a six-hour connection. Convert each leg into packs at the rating you trust, and see which leg is short before you leave the house.

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 cool-box pack tally: your journey leg | hours in transit | ice packs planned stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Ambient heat, an open lid and an ageing pack all reduce cooling hours. After: the cool-box pack tally shows the working beside each named row so the reader can change the assumption and inspect the consequence.
2 · Read the cool-box pack tally
This is packing arithmetic on hours and pack ratings you supply and is not a temperature guarantee or medical-storage advice. Check the labelled storage range for each medicine, the cool box’s own rating and the carrier’s rules with a pharmacist or the manufacturer before you travel.

Boundary and sources
This is packing arithmetic on hours and pack ratings you supply and is not a temperature guarantee or medical-storage advice. Check the labelled storage range for each medicine, the cool box’s own rating and the carrier’s rules with a pharmacist or the manufacturer before you travel.
- Method: A pack still in the freezer or only part frozen adds nothing, and packs take many hours to freeze. Count the packs you can take today, and check the box seals and closes properly with them inside.
- 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 cool-box pack tally, 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 cool-box pack tally. Return plain rows only: journey leg | hours in transit | ice packs planned. 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: journey leg | hours in transit | ice packs planned. No AI response is executed as code.
