How blu works diagram

E-cigs heat liquid and the liquid is converted to vapor. The blue light tip lights up to show you’ve got a charge - and to let people know you’re vaping. Here’s what happens when you inhale:

1. Taking a draw activates the battery

2. The battery power heats the liquid

3. The liquid is converted into vapor
