Frequently Asked Questions

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

A: Battery life varies depending on the speed setting used. At lower speeds, the 4000mAh battery can provide several hours of continuous use. Higher speed settings with the semiconductor cooling active will consume more power. USB charging lets you easily top up the battery from any standard USB power source.

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

A: Unlike a standard fan that only circulates air, the HOMEFISH fan features superconductive ice porcelain semiconductor cooling technology. This actively draws heat away from the contact surface, delivering a noticeably cooler sensation — similar to a cold touch — in addition to the airflow, for a more refreshing experience.

Q: Can I use the HOMEFISH handheld fan while it is charging?

A: Yes, the fan can typically be used while plugged in via USB. The built-in protection chip monitors charging and operation to help prevent overheating, over-discharging, and overcharging during use.

Q: Is the HOMEFISH portable fan suitable for outdoor use?

A: Absolutely. Its compact, lightweight design and high-capacity rechargeable battery make it ideal for outdoor settings such as festivals, sporting events, travel, hiking, and more. The 100-speed settings let you adjust the airflow to suit any environment.
