Thanko Neck Cooler Slim

Wearable personal cooling device

It's a fact: if your head is cool, you can deal even with the worst summer heat, including the infernal sticky heat of Tokyo and its surrounding prefectures. And what is the best way to achieve that? One of the most common tricks the Japanese have found are neck coolers, which feature two aluminum plates you can attach to the sides of your neck and which can be up to 17°C (62.6°F) lower than the environment temperature. Or at least, they will if they are the Thanko Neck Cooler Slim!

The Thanko Neck Cooler Slim comes in two colors so you can actually use it as an accessory to go with your clothes – that's why Thanko has made it slimmer than other neck coolers in the market. But not let its size fool you: powered from the rechargeable 3.7 V (2,000 mAh) lithium-ion battery that comes with it or from any USB power source, its plates deliver anywhere between one and 10 and a half hours, which makes it good even for a full work day out in the heat – including a couple of hours of good old-fashioned Japanese overtime!
