Easy-to-use and beautiful summer usb small fan-Recommended summer portable usb small fan

In hot summer, when we go out for business or shopping, there is no chill of air conditioning, and we are often too hot to open our eyes. At this time, we need a portable small fan, preferably with usb interface, which is convenient for charging. It would be better if the wind is strong and the sound is low. Next, I would like to recommend several cheap and practical portable small fans. Get started as soon as you are satisfied!

The small USB fan in my heart had better meet the following five requirements (for production test only).

1. Yan value! Yan value! Yan value! Yan value justice!

Because I am a visual designer, I sometimes have some paranoia about the appearance of products, that is, products with good face value can stimulate my desire to buy and use (that is, works of art that have no function as long as their face value is not mentioned). Especially in hot summer, I have to hold the small fan in my hand or put it on the table. Isn't it embarrassing to be ugly?

2. It must be charged through USB and used for more than 3 hours after charging.

Usually I ask for a duration of more than 3 hours, and very few can reach 6 hours, unless I have been in low battery mode. However, if you are at school, five hours should be enough, even if you are out of town, five hours is more than enough. Don't consider it within 3 hours, not if the gear is slightly higher.

3. The size of the fuselage is within 100cm width.

Because the usage scene often changes, a small fan that can be put into a backpack or bag is the most suitable choice. In fact, 100cm sometimes doesn't know how to judge. In fact, it's just a circle bigger than your own palm (if you have a generous palm, please look at the size).

4. Weighing less than 200 grams

In fact, it's almost the same as a mobile phone, less than 150g, which is the most comfortable to hold. In fact, it's no different from a mobile phone.

5. Noise, less than 40dB or about 40 dB is good (decibel calculation unit)

According to Baidu Encyclopedia, below 40db is mute. The current small fans are not bad in power unless they are inferior, that is to say, if there are gears, the wind is sufficient. However, I once bought a small fan in some shops, such as shopping malls, with high face value and strong wind power. However, the key point is that you can use 12 hours after starting the third gear. In fact, after opening the third gear, the power went out for two hours.
