These are the most common vaporizers, and therefore the most widely available. They are called session vaporizers because once you turn them on, they heat your herb continuously for a “session”. A Typical session is 5-10 minutes, and some vaporizers will allow you to customize the length. But no matter how long the session lasts, once you start vaping, you have to use all the herb that’s in the chamber.
There is no stopping and starting here. The oven of these vaporizers will continue to heat the herb whether you’re inhaling or not, so if you stop inhaling, you will just end up squandering the herb as it wastes away under the hot air.
“Session” vaporizers have no learning curve and are simple and easy to use. We recommend these to all new vapers. A Session vaporizer with a small “solo-size” oven, will be just as efficient with your herbs as an on-demand vaporizer. A couple of good examples are the Arizer Solo 2 and the Atmos Astra 2.
On-demand vaporizers only heat up when you inhale from them and cool down as soon as you stop. So instead of having to vape all of your
On-demand vapes typically use convection heating system. This means that the heat is generated away from the oven (and herb), and then pulled into the oven with each
On-demand vaporizers are relatively rare and they are usually more expensive than session vaporizers. Most also have a learning
Session VS Demand, Which One Is Better?
The better type of vaporizer really comes down to personal preference since they both have their ups and downs.
- Common and widely available at a variety of different price points
- They are generally very easy to use
- They usually provide a consistent vaping experience for the length of the session
- Most have large bowls that can hold a lot of herb
- Some of them allow you to set your session length
- You need to vape all the herb in one session or some of it goes to waste
- You don’t have a choice in how much—or how little—you want to vape
- The constant heating means that some session vapes can run hot
- The constant heating is also a drain on the battery
On Demand Vaporizers:
- They allow you to use the amount of herb that you want
- You can vape whenever you want
- Near instantaneous heat up times
- Since the heating isn’t constant, battery life is much longer
- These vaporizers tend to stay cool to the touch
- They are typically more complex to use than session vaporizers so are not recommended for beginning vapers
- They are usually more expensive than session vaporizers
- Since heating is intermittent, vapor quality is not always consistent
- Small bowls may rankle some users
