Will my pens fit?
Up to 5 slim injector pens, 6 × 10 ml vials or 25+ peptide vials, caps on. The chamber is 178 mm tall and 50 mm across.
Can I fly with it?
Yes, in your carry-on. TSA allows medication and a battery-powered cooler through screening; tell the officer it’s medication. Keep it in the cabin rather than a checked bag, and check your airline’s battery rules. Flying guide

Measure your longest pen with its cap on: the chamber is 178 mm tall. And check the label on your insulin or peptides for its storage range before you rely on any cooler. See specifications

WHY PEOPLE BUY ONE
Life doesn’t stay in one place.
Neither should your routine.
Insulin, GLP-1 and peptide pens need to stay cold.
An ice pack gives you a few hours and a damp bag. This gives you a number on a display and up to two days.
ON DECK, MIDDAY
Sun on everything else.
Not on your vials.

WHAT TO SET IT TO
Most labels say
2 to 8°C.
The display goes from 0 to 18°C. Here’s where most people land. Your label has the final word.
2–8°C36–46°F
Unopened insulin and GLP-1 pens
The fridge range on most pen labels. Don’t let them freeze.
2–8°C36–46°F
Reconstituted peptide vials
Once mixed, most vials go in the fridge range. Check your vial’s instructions.
Not 0°C32°F
Anything that says do not freeze
Frozen insulin is ruined even after it thaws. Keep the setting above 2°C.
In-use pens can often stay at room temperature for weeks. Your insulin, GLP-1 or peptide label lists the exact range and how long.
FIRST DAY
Less fuss.
More out the door.
Charge it.
Charge the battery, click it in, hold the power button. That’s the setup.
Pick a number.
Tap plus or minus to the range on your insulin or peptide label. Give the chamber time to get there, then check the display.
Load it and go.
Pens or vials in, lid on. Glance at the display now and then. Past two days, pack the USB cable.
Will my insulin pens or peptide vials fit?
The supplier lists an internal chamber 178 mm tall and 50 mm in diameter. Measure your longest pen or vial, including its cap, before ordering. Capacity depends on the shape and size of your containers; medication is not included.
How many Mounjaro or Ozempic pens fit?
Five slim pens like Ozempic, Lantus, Humalog or NovoLog. Three Mounjaro, Zepbound or Trulicity single-dose pens, which are wider. Mixing them, two Mounjaro and two Ozempic fit together. Every pen stands upright with the cap on; anything up to 7 inches (178 mm) long fits.
What temperature can I select?
The supplier advertises a 0–18°C (32–64°F) adjustable setting range. A selected setting is not a guarantee of the temperature inside your insulin or peptides: ambient heat, power and loading affect performance. Check the storage instructions for your exact insulin or peptide and verify the temperature before use.
What comes in the box?
The black cooler, one rechargeable battery, a wall charging adapter, a charging cable and a carrying bag with strap. Medication is not included.
How long does a battery last?
The supplier rates a full charge at up to 48 hours. Real runtime depends on your temperature setting, ambient temperature and how often you open it. For longer trips, plan access to a compatible power source and follow the supplied charging instructions.
Can I fly with it? Is it TSA approved?
TSA doesn’t certify or “approve” coolers, but it does allow medically necessary medication, cooling packs and a battery-powered cooler in your carry-on — just tell the officer at screening. Keep it in the cabin rather than a checked bag, since its rechargeable battery and your pens travel with you. Check your airline’s current battery and medication rules before you fly; acceptance is the airline’s call, and don’t leave the cooler in a hot parked vehicle.
When will my order arrive?
US shipping is free. Orders typically dispatch within 1–2 business days, with estimated delivery in 7–14 days. Delivery estimates are not guarantees; tracking is provided when your order ships.
What if it isn’t right for me?
Our store offers a 30-day return window and a 12-month warranty for manufacturing defects. Use the support contact on your order confirmation to request help with an order, return or warranty claim.
