Thanko Neck Cooler Pro R4

It does have a cyberpunk, post-apocalyptic look and might make you look like a character from a sci-fi manga (not that that's a bad thing!), but don't let its industrial looks fool you: the Thanko Neck Cooler Pro R4 is your best ally against a hot summer, even like those you'd get if you were working construction in Tokyo in August. With three modes (high power, high, low) to chose from, its cooling plates can go anywhere between 4°C (39°F) and 15°C (59°F) lower than the environmental temperature. And if your neck feels cool, so does your head and then your whole body follows!

The Thanko Neck Cooler Pro R4 is size-adjustable, allowing for neck circumferences from 37 cm (14.5") to 50 cm (19.6"). It gets its power from its dedicated battery, but also comes with extra USB cables so you can use it with any USB mobile battery or a continuous source. This means that its running time can be anywhere from two hours (for the high power mode on a fully charged dedicated battery) to practically forever (on a continuous source)! No matter where you are or what time of activity you are doing, it keeps you cool while everyone around you suffers!
