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:

  1.  remove the lights and flowcaps from the end tubes 
  2. detach the flowcaps from the capsule lights 
  3. 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.
