The hot summer has passed, but it also makes us appreciate the power of autumn tigers. Recently, the highest temperature has been kept at 32-34 Between ℃, this temperature is a pain for me, a 70 year old man with periarthritis of shoulder and cervical spondylosis who dare not blow the air conditioner (accidentally exposed his age). Fortunately, there is a small USB fan on my desk with me, and I passed the Love to play computer games The community successfully applied for a small fan of Fantasy Wind, which completely solved my problem. If you want to know the effect of this small fan, let me tell you in detail.

First time meeting out of the box - simple, beautiful, small and portable

The packaging design of the Fantasy Fan is simple. The front and back of the environmentally friendly paper packaging box are identical. The main colors are printed with the product name, trademark and the sample of the fan in white.

The background color on the side of the box is blue, which echoes with the white on the front and back, giving a fresh feeling. The side is mainly about product introduction and operation instructions.

Open the packing box and you will see that the accessories of the small fan are very simple. First, come to Zhang Quanfu, the small fan of Mirage Sound, the company's main product introduction (products are quite rich), charging data cable, certificate of conformity, and warranty card.

The small and simple appearance design of the Fantasy Wind Fan makes people like it at first sight. The whole body is made of white ABS resin, which is not only environmentally friendly but also durable. There are only two wind speed adjustment buttons "+" and "-" on the front, which are clear at a glance. They are natural wind and strong wind, which can be switched freely to meet various needs. At the same time, the "+" key also has the function of the power on key. Press and hold this key for more than 2 seconds to power on, and the "-" key also has the function of the computer key. Press and hold this key for more than 2 seconds to power off.

The back of the small fan is equipped with a fixed screw port, a charging indicator (the indicator will also flash when the power is low during operation), a MicroUSB charging interface, and a hidden bracket.

The concealed bracket is still useful. It can adjust the blowing angle of the small fan of the phantom wind, but I think there is still some shortcomings here, because this bracket can only adjust a fixed angle. It would be better if the design could be improved to adjust it from multiple angles, such as the design of the desktop USB fan in the following figure.

For the design of the product, I personally think there are two other points that I highly praise. The first is the use of the anti slip pad at the bottom of the small fan, which is very considerate. The second is that the small fan is equipped with a leather sling, which can be hung or held in your hand, as you wish, and is easy to carry.

Try to have a good taste - strong, powerful and slightly inadequate

To be honest, many testing tools are needed for professional testing of the Fantasy Fan, which is not available to non professionals like me. Therefore, I can only make a trial analysis of the fan from the perspective of ordinary users. The small fan of Mirage Wind is equipped with 1200mA lithium ion battery as standard, which can be used without external power supply. Its rated power is 1.2W. When starting up for the first time, drain the battery of the small fan and conduct the charging test. The battery is charged for the first time from 0 to full charge The status actually takes 125 minutes. Because fast charging is not supported, the speed is fairly good. During the charging process, the charging indicator will keep flashing, and the indicator will stay on when the battery is fully charged.

After the battery is fully charged, the endurance of the small fan will be tested. After starting up, the fan will stop automatically after running for about 140 minutes in the lowest wind speed gear, and will stop automatically if running for about 80 minutes in the highest wind speed gear. It can be seen that the battery life of the small fan is slightly weak, but after all, the standard battery is only 1200mA. If you really need to use it outside, you can consider using the power bank to "refuel" the small fan for life.

The air volume test is not easy to show without professional tools. Now I will show the air volume through the animation effect of the same red rope blown by the low and high speed of the small fan of Mirage Wind and my original Deli USB mini fan (voltage 5V, power 2.5W) (Figure 1 shows the low speed of the small fan of Mirage Wind, Figure 2 shows the high speed of the small fan of Mirage Wind, and Figure 3 shows the small fan of Deli USB desktop).

Fig. 2 High gear mode

Figure 3. Deli USB Mini Fan

Through the above dynamic comparison, it is judged that the air volume of the high speed gear of the Phantom Wind Small Fan is quite close to that of the Deli USB Mini Fan, and the wind power is strong.

Personally, I think the running noise of the Fantasy Fan is a little high. Without professional equipment to test the noise, I can only download a Chinese version of the noise meter from my Android phone for a simple test. The noise of the fan in low speed gear is about 48 points, and the noise of the fan in high speed gear is about 55 points, The test value may not be too accurate, but it can be used as a reference.

Feelings after trial - worth buying but still improving

After a period of trial, I feel that the Mirage Fan is still worth having. It has a simple and beautiful appearance, environmentally friendly materials, small and portable size, and strong wind power. However, there are still some shortcomings that need to be improved. The battery capacity is small, the endurance is slightly weak, the fan cannot be adjusted from multiple angles, and the motor noise is slightly high. As for the price, the price of 79 yuan is acceptable. If the price remains unchanged after improvement, it will definitely explode.
