I want to travel for 5-7 weeks, so wish to keep my insulin at fridge temperature (2-8’C) for the entire outward journey, whether this be boat or airplane. Does anybody have any experience of using (and tempering) the biogel-packs that are used for keeping some cooling flasks at 2-8’C for long periods of time? (For example, The Voyager Cooler made by 4AllFamily but there are many other examples of this technology.) I am considering a battery-powered tiny fridge, such as Lifeinabox or the Voyager Cooler works in passive or battery mode. However, I wish to first ascertain whether the passive gel-pack coolers are worth considering. In my past experience, the tempering process is vastly different to the manufacturer’s instructions and not at all user friendly. Wondered if anyone has any recent experience please.
