Rechargeable fans are convenient, but they are still battery-powered electrical products. Before launching or buying at scale, documentation and sensible use matter.
For customers
- Use the supplied cable or a suitable 5V USB source.
- Do not use a damaged cable, swollen battery, or hot device.
- Keep fans away from water unless the product is specifically rated for it.
- Do not leave charging devices buried under bedding or fabric.
For buyers and store owners
Ask suppliers for product markings, test reports, battery documentation, English instructions, and clear model numbers. For UK sales, treat product safety and battery compliance as core launch work, not admin later.
