The ability to adjust the temperature of a vaporizer plays a major role:
- Temperatures between 290F-330F give off smoother-tasting vapor and results in a milder feeling
- Higher temperatures – 400F and up – result in larger clouds, and more intense high
The best models have many heat settings. This allows the user to set their temperature. The heating-style is also important.
The two most common heating styles of modern units are:
Conduction means stuff comes into direct contact with a heat source. Convection means hot air passes through the material. The two styles have their pros and cons. Conduction devices use less power than hot-air units. Their battery life is longer. One bad thing about conduction is material gets wasted. Any loose-leaf material that is not in contact with the heating element does not get vaped.
Convection-style units offer better use of materials. These types of models create hot air and blow it through a chamber packed with marijuana. Like the way, a hair-dryer dries hair. Except, hot-air ovens use more power and drain batteries quicker than the direct-contact ovens. The final thing that makes ups the best personal vaporizer is its chamber material.
This comes down between two options:
Each element has its fans as well as its critics. Early chambers were ceramic. Ceramic is cheap and does not react to heat. A ceramic oven also makes a vaporizer lighter. Some cons of ceramic ovens include being hard to clean and breaking quickly. Devices with steel ovens cost more and are heavier. The best portable herbal vaporizers assure no bad materials get into the vapor. Their build materials also do not react to high heat. Stainless steel also heats up faster than ceramic. Since they are not as porous as ceramic, steel chambers are easier to clean.
Stainless steel also has better conductivity than ceramic, although ceramic heats more slowly and evenly. Ceramic elements are less likely to overheat and combust the weed. Once again, there are pros and cons to every type.
