It looks like it has an atomizer and cartridge. First, the batteries should have some charge, so you can get started right away. - Put one battery on the charger.
- Fill the cart with a few drops of your juice. Drip a few drops into the cart filling. Let the batting absorb the juice and drip some more until the juice doe not get absorbed anymore. The batting should look wet without any pooling.
- Screw the atomizer into the battery and place about 3 drops of juice to prime it.
- Insert the filled cart into the atomizer and you are good to go.
Good luck...
