Why this matters
If you compare two dry herb vapes at the same price and one feels markedly better than the other, the heating system is usually why. Convection, conduction and hybrid designs each produce distinct sessions even when temperature settings match.
Understanding the difference helps you read product pages with a sharper eye and pick a device that fits your style — fast and dense versus slow and flavorful.
What to look for
Conduction
Heated chamber walls toast the flower in contact with them. Fast to start, dense vapor, but uneven extraction if you don't stir.
Convection
A fan or your draw pulls hot air through the flower. More even extraction, cleaner flavor, but generally slower heat-up.
Hybrid
A heated chamber plus convection airflow. Most premium portables now use this — it splits the difference well.
Draw resistance
Pure convection often draws lighter; conduction can feel restrictive. Hybrid sits in between.
Battery drain
Convection generally pulls more current, especially in on-demand devices. Conduction sessions drain a battery steadily over a fixed time.
Maintenance
Conduction chambers gunk up faster from prolonged flower contact. Convection paths still need cleaning but less frequently.
Budget, mid range or premium?
Here is what each level actually buys you.
Budget conduction
$60 – $130
A simple heated chamber with one or two preset temperatures.
Best for
First-time vape buyers, casual users.
Mid hybrid portable
$150 – $280
Heated chamber with active convection airflow and precise temperature control.
Best for
Most users — the modern default for portable dry herb gear.
Premium on-demand convection
$300 – $500
Fan-driven or true convection with instant heat-up and very even extraction.
Best for
Flavor chasers and frequent users who want every bowl perfect.
Watch out for
Steeper learning curve and higher price.
Common mistakes
MistakeBuying a pure convection vape and expecting it to heat instantly.
FixMost convection units need 20-60 seconds before draws are dense. Devices like the Mighty cheat the wait by combining conduction.
MistakeTreating a conduction vape like a session — forgetting to stir.
FixStir or shake the chamber once mid-session. The center of the bowl gets less heat than the walls and extracts unevenly otherwise.
MistakeComparing temperatures across heating types directly.
Fix390°F on a conduction unit and 390°F on a convection unit produce different vapor. Use temperature as a starting point, then adjust by feel.
MistakeDismissing hybrids as 'neither here nor there.'
FixHybrids are now the dominant portable design for a reason. They give you fast heat-up and reasonably even extraction in one device.
MistakeIgnoring airflow design.
FixRestricted airflow can ruin even the best heating system. Check reviews specifically about draw resistance before buying.
The full guide
Conduction in detail. Conduction devices like older PAX models use a heated oven that toasts flower in direct contact. They are simple, compact and cheap to manufacture. The downside is that the flower against the chamber walls cooks first, while the center stays cool — you get a top-down extraction unless you stir.
Convection in detail. True convection devices use a separate heat source and an airflow path. Hot air passes through the flower only when you draw or when a fan pushes it through. This produces very even extraction because every particle of flower meets the same hot air. It also preserves terpenes better because the flower isn't being slowly toasted between hits.
Hybrid in detail. Most modern portables use a heated chamber plus a convection draw. The chamber pre-warms the bowl so the first hit is dense, and the airflow finishes extraction. Devices like the Mighty, Crafty and many newer units fall into this category.
Which to pick. If you want simple, cheap and fast, conduction. If you want maximum flavor and don't mind waiting, true convection. If you want a balanced session that works for most people most of the time, a hybrid is the safest pick.

Common Questions
Is convection better than conduction?
Not universally. Convection extracts more evenly and preserves terpenes, which most enthusiasts prefer. Conduction is faster to first draw and cheaper. For everyday use, hybrid designs combine the strengths of both.
Why does my conduction vape taste burnt?
Either the temperature is set too high, the bowl is left heated too long without drawing, or the flower isn't being stirred. Try lowering the temperature 10-20°F and stirring at the halfway point.
Do convection vapes save more flower?
Slightly, because extraction is more even and you waste less flower at the bottom of the bowl. The difference is real but not huge — maybe 10-20% more sessions per gram in side-by-side use.
Are on-demand convection vapes worth the price?
If you take 1-3 hits at a time rather than long sessions, yes. On-demand units only heat when you draw, so a single bowl can last days. For session users, the value is smaller.
How do I tell what a device uses?
Check the manufacturer's product page or any teardown video. Reputable brands always state the heating method. If they don't, assume basic conduction.
