Does this fan really have 100 different speed settings? Could it just be a marketing gimmick?
ColdSky’s turbo fan offers 100 precise speeds, from gentle breezes to powerful winds. Easily adjust settings for commutes, offices, or outdoors using responsive buttons. Enjoy customized airflow tailored to your exact cooling needs.
Is the fan heavy? Is it convenient to put in a pocket?
It's extremely lightweight! The entire machine weighs only 5.8 ounces (about 164 grams), which is lighter than most mobile phones. The design is compact, and it can be easily placed in a jeans pocket, a small backpack, or a lady's handbag.
How long does it take to fully charge? Does it support fast charging?
It supports USB-C fast charging. With a charging head of 5V/2A or higher power, it takes approximately 2-3 hours to charge from 0% to 100%. You can recharge it anytime using a portable power bank, a laptop, or a car charger, which is very convenient.
Is the noise loud when it's running at high speed? Is it suitable for offices or libraries?
Levels 1-40 are whisper-quiet, ideal for offices or libraries. Levels 80-100 produce a low turbo hum, much quieter than hair dryers. For absolute silence, we recommend using speeds below level 50.
