You cannot use a power bank to charge your Mamamoo lightstick because it uses batteries, not a rechargeable battery pack 🌟. The lightstick requires you to insert batteries, such as AAA batteries, to make it work, and these batteries cannot be charged directly from a power bank 💻.
If you want to use a rechargeable option, you might need to purchase a separate rechargeable battery pack that is compatible with your lightstick, but this would require replacing the existing battery setup 🔋. However, for the Mamamoo lightstick, it is designed to use disposable batteries, so using a power bank is not an option 🚫.
To keep your lightstick working well, remember to remove the batteries when you are not using it to prevent them from draining or causing damage to the lightstick 🌱. This will help extend the life of your lightstick and ensure it continues to function properly during concerts or other events 🎉.
