Using the Pochacco Mood Light is a breeze. To adjust the brightness, just tap the light three times and it will cycle through different levels. When it's time to charge, use the provided USB - C to USB cable and plug it into a standard USB socket. Keep in mind that it's best to charge the light in a cool and dry place. Avoid exposing it to excessive moisture or direct sunlight, as this could damage the light. For maintenance, you can gently wipe the surface of the light with a soft, dry cloth. This will keep it looking clean and cute. With proper use and care, your Pochacco Mood Light will provide you with a warm and cozy glow for a long time.
