It comes fully equipped with a rechargeable lithium ion battery, 2 Nuke cartridges, a cartridge shell, rubber mouthpiece, mouthpiece cover, retractable USB charger, wall adapter, syringe bottle, and a user guide direction manual. This pen herbal vaporizer is different than all the other vaporizers because it has two tank chambers rather than one. You fill each separately with your desired concentrate or liquid essential oil. The newly enhanced addition of a switch allows every user to switch it to single or double cartridge use. You can use one tank at a time ore have a combination blend by heating both at the same time. This gives the option of creating your very own custom blends. The Atmos Nuke brings the term double-time to the world of vaporizers. Along with the retractable USB charger for charging anytime anywhere, this pen-style vape brings everything you need to the table for an on-the-go lifestyle. As with all the other Atmos products, this vaporizer includes one power button with a blue LED light indicator. It glows whenever pushed and blinks as an alert when the battery is in need of a charge or if auto-shut off is being activated. It also features a lock which requires five continuous clicks of the power button for the unit to be powered on.
