The BlitzWolf BW-NF1 is a 2021 new neck fan and battery powered, so it cools you down wherever you are. So if you’re out hoeing in the summer in the ‘sweltering heat’, it’ll make your work a little more bearable, but it’s also useful indoors. The price is currently 24.99 USD.
By the way, there are similar solutions out there, but they look kind of cutesy compared to the BlitzWolf BW-NF1, which actually looks pretty damn good and mimics a headphone quite well.
It can be bent on demand and the fan part can be rotated to blow air in the right direction. It has an 1800 mAh battery that can push air in your face for up to 7 hours, with three power settings. It can be charged via a Type-C connector.
