FAQs
Q: How do I know when it’s fully charged? A: Typically, a red light flashes during charging and stays solid (or turns off) once the fan is fully charged.
Q: Can I use the fan while it is charging? A: Yes, but ensure the “Anti-trigger” switch at the bottom is in the ON position. Note that charging might take longer if the fan is running.
Q: Why won’t my fan turn on even after charging? A: Check the bottom of the handle/base for a small physical slider switch (Anti-trigger switch). This must be flipped to the “ON” position before the power button will work.
Q: Is it safe for children? A: While the blades are housed behind a grille, it is recommended to keep it away from very young children to avoid fingers being poked through the gaps.
