Introduction
When choosing a dry herb vaporizer, one important feature to consider is how it delivers heat: on-demand or session mode. Both approaches have unique advantages, and the right choice depends on your lifestyle and vaping habits.
This guide explains the difference between on-demand and session vaporizers, with examples of the best models available at DopeVapes.co.uk.

What is On-Demand Mode?
On-demand vaporizers heat your herb instantly when you inhale or press the button, allowing for short, controlled draws without committing to a full session.
Pros:
- Instant heating (often just a few seconds)
- Great for microdosing and conserving herb
- Perfect for quick, discreet use
Cons:
- Smaller chambers
- Learning curve for consistent results
Recommended On-Demand Vaporizers at DopeVapes:
- Tinymight 2 — Elite on-demand convection vape with outstanding flavour, swappable batteries, and session mode flexibility.
- Dynavap M7 XL — Battery-free and nearly indestructible. Heated with a torch or induction heater, perfect for quick hits on the go.
- XMAX V3 Pro — Affordable option with both on-demand and session modes, plus dosing capsule compatibility for cleaner use.

What is Session Mode?
Session vaporizers heat the chamber to a set temperature and keep it warm for the duration of your session, much like smoking a joint but without combustion.
Pros:
- Great for group use and longer sessions
- Larger chambers for more herb
- Consistent vapour production
Cons:
- Less efficient if you only want a few quick draws
- Consumes more herb per session
