Thanko Cool Backpack 2

USB-powered rucksack-shaped back cooler

It isn't just about avoiding that awful feeling of a wet bag sticking to your sweaty back or about keeping the contents of your bag from getting wet themselves: what makes the Thanko Cool Backpack 2 such a lifesaver is that it not only does all of the above but also keeps you cool. How cool? As much as -14°C lower than the ambient temperature.

How does it do it? Using a combination of three cooling plates and three fans that are stored inside its secondary compartment, the Thanko Cool Backpack 2 not only creates a low-temperature environment but spreads it around your back. All you need to do is hook it to a USB 5 V 2 A or higher battery or power pack. And with a capacity of 2.5 liters in its the primary compartment, three inside and one outside pockets, and adjustable shoulder and chest straps, this is a pretty handy everyday bag too!
