How strong is the airflow compared with a normal mini fan?

The BLDC motor is rated to 17,000 RPM, well above the small brushed motors in most pocket fans. Expect a focused, strong breeze rather than a wide one, since the head is small.

How long does the battery last?

The 2,000mAh battery lasts longest on the lower speeds and drains fastest at the top level. The LED display shows remaining charge so you can judge before it dies.

Is it loud at full speed?

The brushless motor and honeycomb vents are designed to keep noise down, but a fan spinning at 17,000 RPM is audible. Lower speeds are the quiet option.

Can I use it while it charges?

The listing does not state pass-through charging, so plan to recharge between uses rather than run it plugged in.

What comes in the box?

The fan itself. A charging cable is not listed, so check that you have a USB cable that fits before you rely on it.

Is it good for makeup setting?

Yes. The low speeds give a soft, steady breeze for drying setting spray or powder without blasting your face, which is why the brand markets it for makeup routines.
