Fan head 5-10V voltage input speed regulation color random hair DIY research price

The fan head is made of good materials. The plastic shell is made of very tough material, which is difficult to crush. I tried one with red connected to the negative and white to the positive before turning. It may be that the wrong polarity during production does not affect the use. The wind is normal at the beginning of 5V, and the voltage can be adjusted to 10V for normal long-term use. When it reaches about 12V, it will automatically protect and cut off the output. At about 10V, the wind is very strong, and the power is more than 3 watts. The color is random, and there is a yellow one.
