Safety briefing
Many cooling devices use rechargeable lithium-ion batteries, the same type of battery found in phones and laptops. While these batteries are generally safe, they can become dangerous if they are damaged, overheated, or charged incorrectly. In rare cases, a faulty lithium-ion battery can catch fire or even explode. To reduce the risk, avoid leaving products in direct sunlight, hot cars, or near sources of heat. Always use the charger supplied with the product, or one recommended by the manufacturer, and avoid using electrical products that have been dropped, damaged, or exposed to water. If the battery starts to swell, the fan becomes unusually hot, or you notice a burning smell, stop using it immediately.
