Frequently Asked Questions

Q: How long does the 4000mAh battery last on a single charge?

A: Battery life depends on the fan speed setting used. At lower speeds, the 4000mAh battery can provide several hours of continuous use. At maximum speed with the semiconductor cooling active, run time will be shorter. Recharging is easy via any standard USB power source.

Q: What makes the semiconductor cooling technology different from a regular handheld fan?

A: Unlike a standard fan that simply circulates ambient air, this HOMEFISH fan uses superconductive ice-porcelain semiconductor refrigeration technology to actively lower the temperature of the airflow it produces. This means the air directed at you feels noticeably cooler than the surrounding environment — not just moving warm air around.

Q: Is this fan safe to use for extended periods?

A: Yes. The built-in protection chip monitors the device continuously and safeguards against overcharging, over-discharging, and overheating. The quiet brushless motor is also designed for long-lasting, efficient operation. Always use the included USB cable or a reputable USB charger for recharging.

Q: Can I use this fan while it is charging?

A: The product supports USB charging via a 5V input. While use during charging depends on the specific charging cable and power source, the built-in protection chip helps ensure safe operation. For best performance, it is generally recommended to allow the battery to charge fully before extended use.
