Dual Use Portable Vape The Tera's pure convection heater provides rich, pure flavour and the stainless steel loading chamber retains a small amount of heat from the air with each draw, adding a touch of radiant conduction to improve extraction efficiency and cloud production without cooking your material between hits. The Boundless Tera is the first dry herb vaporizer with dual removable 18650 batteries, a feature the community has been requesting for years. Two high-output 2500mAh batteries are included for an impressive run time from the box and if spares aren't available you can charge the Tera through standard Micro-USB. The Tera's crisp and clear top facing OLED screen displays remaining battery life and current temperature ranging from 140-446°F.
