Check Ice Packs Against the Hours in Transit — Free
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.
The proof surface
Fridge-outage and refill tools cover stored supply at home. This converts the hours of each journey leg into ice packs at the cooling hours you set, and never claims a temperature or storage result.
Why the flat version breaks
Treating the rating as a guarantee
Ambient heat, an open lid and an ageing pack all reduce cooling hours.
Counting unfrozen packs
A pack that has not frozen solid cannot be counted as cover.
Repacking medicines unlabelled
Keep medicines in their labelled packaging and ask a pharmacist before transferring anything.
How to work the cool-box pack tally
Start from the pack maker’s figure and then apply your own experience on hot days, a part-filled box or an older pack. Enter the cooling hours you would rely on, not the best case on the box label.
Count door to door including changes, waiting rooms and the drive at each end, since the box is out of the freezer the whole time. A six-hour leg with a three-hour wait is two rows, not one short trip.
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.
A leg needing more packs than planned is flagged. Ask the pharmacist about storage ranges, labelled packaging and any carrier rules, and consider a shorter route rather than trusting the count.
What the cool-box pack tally replaces
| Question | Before | Visible working |
|---|---|---|
| Treating the rating as a guarantee | Ambient heat, an open lid and an ageing pack all reduce cooling hours. | Enter each leg’s real hours |
| Counting unfrozen packs | A pack that has not frozen solid cannot be counted as cover. | Count only packs ready to use |
| Repacking medicines unlabelled | Keep medicines in their labelled packaging and ask a pharmacist before transferring anything. | Act on the flagged legs |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

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.
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.
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.
Go deeper: the companion app files the same reading as a meter band gauge
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the cool-box pack tally reading, and holds your drafts on this device — one complete free run; the proposed $4 one-time filing layer is not currently for sale.
The cool-box pack tally reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- 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.
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.
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.
