Internal usable space accommodates standard insulin pens. Customers regularly carry Lantus, Tresiba, NovoLog, Humalog, Ozempic, Wegovy, and Mounjaro without modification. Approximate count and confirmed-fit list is on the product page.

Up to 8 hours of cooling on a full charge, depending on ambient temperature and how often you open the lid. Plug into the 12 V car USB or a wall adapter for unlimited runtime, and carry a spare swappable battery for long-haul flights.

Yes. The cooler is sized to fit cabin carry-on personal-item dimensions, and the lithium battery is within IATA carry-on limits. Personal medical devices and the medications they hold are generally permitted in the cabin under FAA, EASA, and CAAC rules — declare it at security and carry your prescription. The travel guide has country-by-country notes and a downloadable doctor's-note template.

No. Customers store GLP-1 injectors (Ozempic, Wegovy, Mounjaro, Zepbound), biologics (Humira, Enbrel, Stelara), growth hormone, fertility medications, and breast milk on the go. Anything that needs to stay between 2 °C and 20 °C will work.
