Frequently Asked Questions

Q: How does the semiconductor cooling fan work differently from a regular fan?

A: Unlike a standard fan that simply moves ambient air, the X28 Semiconductor Cooling Pocket Fan uses thermoelectric (Peltier) technology to actively lower the temperature of the air it outputs. This means you get a genuinely cooler airflow rather than just circulated warm air — ideal for hot outdoor environments or stuffy indoor spaces.

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

A: The built-in 1800mAh lithium polymer battery provides extended runtime depending on the speed setting used. The fan charges via standard 5V USB, making it easy to top up with any phone charger, power bank, or USB port.

Q: Can I use this fan on my desk as well as hold it?

A: Yes! The X28 is designed for both handheld and desktop use. Simply prop it upright on a flat surface for hands-free cooling at your desk, nightstand, or workspace, or hold it directly for personal cooling on the go.

Q: Is this fan safe to carry in a bag or pocket?

A: Absolutely. The ultra-slim card form factor (just 21mm thin) and lightweight build (143g) make it exceptionally easy to carry. It contains no high-concern chemicals, making it safe for everyday use and travel.
