Insulin / med cooler — power-outage honesty

• Not medical advice. QuietWatt does not set storage temperatures, discard windows, dosing, or cold-chain rules. Follow your clinician, pharmacist, and the medication / device label.
• Temp claims stay general. We will not invent a “safe °C” for your insulin or cooler. If the label or clinician says keep refrigerated, treat that as their rule — QuietWatt only sizes watts and Wh.
• Not a clinical guarantee. Runtime math is shopping research. Your cooler’s label and a plug-in watt meter win over any directory estimate.
• Life-critical plans need more than a camping battery. Ask your care team about backup medication, travel coolers rated for your drug, and outage protocols. Broader context: medical device backup · CPAP cousin: CPAP sizing.

Framing below is planning honesty (checked Oct 2026 sibling citations) — estimates labelled. Confirm every station figure on the current listing. Check cooler label / listing.

• Read the cooler / mini-fridge label or meter first. QuietWatt will not invent a watt number as fact. Use nameplate running watts, OEM sheets, or a watt meter on your unit with a typical door schedule.
• Compressor cycling ≠ nameplate continuous. Many small compressor coolers are off much of the hour when the door stays shut. Average watts ≈ running watts × duty cycle (fraction of time on). Thermoelectric travel coolers can draw more steadily — different math; still meter yours.
• Raw overnight Wh ≈ average watts × outage hours you care about (pick your window — e.g. 8–14 h).
• Station Wh you need ≈ (average watts × hours) ÷ 0.85 — QuietWatt’s rule-of-thumb for inverter loss + a little reserve (not a lab factor). Usable Wh ≈ nameplate Wh × ~0.85; hours ≈ usable Wh ÷ average watts.
• Surge is a separate gate. Compressor start can trip soft peak limits even when Wh looks fine — peak vs continuous watts. General sizing: what size power station.

Deeper duty-cycle walkthrough: mini-fridge Wh math. Overnight product shortlist (still not medical advice): insulin fridge backup.

• Prefer pure sine AC when the cooler uses a wall adapter / sensitive brick — waveform honesty: pure sine wave. Confirm OEM guidance for your cooler.
• EPS / UPS / backup-mode transfer naming varies by brand — flicker during grid drop may matter if you leave the cooler on pass-through while charged — EPS vs UPS mode · pass-through charging.
• Bedroom / hallway noise is a neighbour test if the station fans under compressor start — apartment fan noise.
• Still not medical advice. Waveform and transfer talk is shopping research, not a clinical endorsement of any cooler + station pair.

1. Clinician + label first — storage / outage protocol is theirs; QuietWatt only does Wh math.
2. Meter or label → estimate average watts (duty cycle), not nameplate alone.
3. Run (avg W × overnight hours) ÷ 0.85 → station Wh floor; watch the ~300–500 Wh fail gate.
4. Check peak / continuous against compressor start — peak vs continuous.
5. Prefer pure sine (or OEM-approved DC path) — pure sine.
6. Confirm listing for Wh, surge, voltage, and price — QuietWatt placeholders are not live prices.

• Anker SOLIX C1000 — mid ~1 kWh class QuietWatt tracks; confirm Wh and surge on listing.
• BLUETTI Elite 100 V2 — mid class; confirm continuous / surge on listing.
• Jackery Explorer 1000 v2 — mid class; confirm live specs.
• EcoFlow DELTA 3 Plus — expandable mid/large class; confirm Wh and surge language on listing.
