If we missed yours, send us a note.
No, Mounjaro and Zepbound pens do not fit this cooler. It supports standard insulin pens and regular GLP‑1 pens only.
5 - 8 hours on a full charge at typical room temperature. Extreme heat or cold will reduce runtime.
Yes — TSA and most international authorities allow medical cooling devices in carry-on. The lithium battery is under the 100 Wh limit. Bring your prescription or doctor's note to be safe.
No — the thermostat holds 2–8 °C and will not drop below freezing. The app lets you set custom thresholds and will alert you if temperature drifts.
No — it works for any temperature-sensitive medication: GLP-1s, biologics, growth hormone, fertility meds, etc. Check your drug's storage range and set the app accordingly.
1 year from purchase, covering defects in materials and workmanship. Accidental damage and normal wear are not covered. Extended plans available at checkout.
The unit has a built-in sensor and an LCD on the front.
No it does not. USB charging is not strong enough to power cooling effectively. We recommend to bring multiple packs of batteries if needed.
Yes — the lid and the fan cover are both detachable and washable. No biofilm traps, no condensation pooling.
15–20 minutes from room temperature to 5 °C, depending on how full it is. Plug it in 15 minutes before you load your medication.
The aviation-aluminum and polyurethane insulation hold residual cold for 2–4 hours. The app and the device alarm before that point so you have time to plug in or swap to a backup battery.
No — it's a precision instrument with a fan and electronics. Don't submerge it. The detachable lid is washable separately.
Yes. Many customers leave it on the bedside or kitchen counter for daily insulin storage and only run on battery when they travel.
