On the side of each capsule light you will see a micro-USB charing port - see photo below.
For lumina twirl batons, you will need to:
- remove the lights and flowcaps from the end tubes
- detach the flowcaps from the capsule lights
- plug the lights into the charger - and you should be all set!
We hope this helps, and if you have any questions please contact us and we will do our best to help out.
