To know if your Mamamoo lightstick is fully charged, you need to understand that it doesn’t charge like a phone; instead, it uses batteries 📦. The lightstick requires three AAA batteries, which you need to insert correctly to make it work 🔋.
When you put the batteries in the right way, the lightstick will turn on and shine brightly 💡. If it doesn’t turn on, it might mean the batteries are not inserted correctly or are weak, so you should check them again 🔍.
If the lightstick is working and shining with all its colors, it means the batteries are good and the lightstick is “fully charged” in the sense that it’s ready to use 🎉. However, remember that batteries will eventually run out, so you’ll need to replace them when the light becomes dimmer 🔋.
