FAQCooling, battery, what fits, returns and warranty.
- Is VialFlask Pro a medical device?
- No. VialFlask Pro is a storage and transport accessory. It's designed to hold a stable, adjustable temperature, but always follow your prescriber's and manufacturer's storage instructions for your specific medication.
- How cold does it get?
- The peltier module is adjustable and holds 0–8°C internally, provided ambient temperature stays under 32°C. The LED display shows the live internal temperature at all times.
- Does it need to stay plugged in?
- No — the built-in battery provides 3–4 hours of cooling per charge at an ambient temperature of 23°C. For longer stretches, use USB-C power from a wall outlet, USB port or power bank. The battery percentage readout and charging indicator help you keep track of power.
- How long does the battery last?
- 3–4 hours of active cooling per charge at an ambient temperature of 23°C. Runtime varies with ambient temperature and your set point. Check the battery percentage readout and bring a USB-C power source for longer trips.
- How do I check the battery and charging status?
- The front panel shows the remaining battery percentage alongside the live temperature readout. A charging indicator shows when the unit is charging over USB-C.
- How big is the new slim unit?
- The overall dimensions are 82 mm wide × 86 mm deep × 255 mm high.
- What fits inside?
- The chamber is 49.5 × 49.5 × 160 mm — sized for standard vials and pen injectors stored upright.
- Can I use it as a portable peptide fridge?
- That's what it is. It actively refrigerates rather than just insulating, holding 0–8°C — the same range as a fridge shelf — from its own battery. Unlike a mini fridge it runs unplugged for 3–4 hours at 23°C ambient and fits in a bag. As always, follow your prescriber's and manufacturer's storage instructions for your specific medication.
- How is this different from an insulated peptide case or cool bag?
- An insulated case or a gel-pack cool bag only slows warming down, and how long it holds depends on how cold it started and how hot the day is. VialFlask Pro cools actively with a peltier module and shows the live internal temperature on its LED, so you can see it holding 0–8°C instead of hoping. No pre-freezing, no gel packs, and nothing to swap out mid-trip.
- What if it's not right for me?
- You have 30 days from delivery to return it for a full refund, as long as it's unopened in its original packaging — and we send you a prepaid return label. Faulty units are always covered regardless, under warranty and Australian Consumer Law.
- What's the warranty?
- Every VialFlask Pro is covered for 1 year, parts and labour — including the peltier module, battery, LED display and USB-C input. If a fault develops in normal use we repair or replace it, shipping covered both ways, on top of your Australian Consumer Law rights.
- How much is shipping?
- Free, Australia-wide. Orders dispatch from Melbourne in 2–3 weeks; from dispatch, tracked delivery takes 1–6 business days anywhere in the country. Express delivery (1–3 business days) is available for $9.99 at checkout.
