What is the 4AllFamily Insulin Cooler?

If you are looking for the best insulin pen travel cooler, look no further, this is the best you could get your hands on. This insulin cooler uses 3 cooling methods and keeps your insulin cool and safe for up to 72 hours. It can fulfill all your traveling needs without any worry.

Why is it the best?

The uniqueness of this cooler is that, by changing the lids you can easily transform the bottle from a regular medication cooler into a mini-fridge. The USB function alone can maintain a constant temperature of around 27°F (15°C) lower than the outside temperature. If you use ice pack as well simultaneously it will give an outstanding cooling effect, such as keeping 35-46°F (2-8°C) cold for 48 hours and 36-46°F (2-26°C) for 72+ hours, when tested at an outside lab temperature of 104°F (40°C). Moreover, it is patented so you will never find the same quality in other insulin coolers.

After testing and using it myself this is worth it. For now you can review all my findings below. I will update this post when I am able to do some longer travels with it.

1. Price (compared to others)

Compared to other brands and insulin coolers or travel case this one might be a bit on the pricy side. But don't forget you get what you pay for and that is absolute quality.

Because it's made out of stainless steel it might dent a bit too easy when dropping it or bumping onto a hard surface. But it is high quality stainless steel which enhances its durability.
