Desktop mini fan, 100V power supply I received this from an acquaintance. The wind is about this strong in the image, perhaps a gentle breeze! It's not USB powered, so it needs a power outlet. It works, but how about using it for interior decoration? It's 15cm x 15cm x 15cm = 45cm in size, but since the shipping size is 60cm, the shipping cost is 750 yen, which is why the price is this high. The wind strength might increase by adjusting the angle of the blades, I don't know though!?!?
