TEMPEST 2 vs. DynaVap M7: Is the Premium Price Worth It?
Two butane vaporizers, no battery, no charging cable — but a price difference of around €90. The DynaVap M7 from Canada starts at roughly €85 and has been the most recommended entry point into butane vaping for years. The MAD Heaters TEMPEST 2 from the UK costs around €173 and claims desktop-level vapor quality without electricity.
At a Glance: The M7 is a precision VapCap device with a click system and fixed bowl (~0.1 g). The TEMPEST 2 is a ball vaporizer using pure convection, six ball options, and three bowl sizes (0.1–0.2 g). Same energy source, fundamentally different principles.

DynaVap M7 — The Click-System Classic
The M7 is made entirely from stainless steel and weighs around 28 grams. The VapCap system is its defining feature: heat the metal cap with a jet lighter until it clicks twice — that signals the temperature is right and vapor is ready. A cooling click lets you know when the load is spent. No electronics, no settings, nothing to break.
Heating is a hybrid of conduction (contact heat through the metal wall) and a small convection component from airflow. For a butane vaporizer at this price point, vapor quality is excellent. The bowl holds roughly 0.1 g — compact and optimised for on-demand sessions.
The 8 mm stem format is an open standard. Thousands of accessories — glass stems, water pipe adapters, coolers, caps — fit straight out of the box. The DynaVap community is one of the most active in the vaporizer world.
Heat-up: 5–10 seconds with a standard jet lighter. Induction heaters (DynaVap Orion, iSpire Wand, YLL 3.0) also work. From ~€85 — DynaVap M7 price comparison
MAD Heaters TEMPEST 2 — Convection with a Ball Matrix
Inside the TEMPEST 2 sit zirconia balls that act as a thermal battery. Air heats up over the balls, then flows through the herb — pure convection, zero contact. The result is even, flavour-forward vapour that rivals desktop ball vapes like the Qaroma or B-Zero.
The body is machined from Grade 5 titanium. The bowl adjusts to three positions: roughly 0.1 g, 0.15 g, or 0.2 g. A double-click mechanism opens and closes the bowl without tools. The 8 mm stem is DynaVap-compatible — the whole accessory ecosystem fits.
Compared to the M7, the learning curve is steeper: heating time needs calibration, airflow matters. But once you know the device, you get desktop-level vapour in your pocket.
Heat-up: 10–20 seconds. Weight: 46 g. Compatible with iSpire Wand, YLL 3.0, Portside Mini, and other induction heaters. From ~€173 — TEMPEST 2 price comparison

Vapour Quality
The M7 produces dense, efficient vapour in one to three draws. The conduction principle heats the material evenly from the outside — fast, direct, and reliable. For an €85 butane vaporizer, quality is genuinely impressive.
The TEMPEST 2 uses pure convection. Hot air flows through the ball matrix, then through the herb — no contact heat at all. The result is more flavour-forward, cooler vapour across multiple draws. Dense clouds are possible, but the profile is aromatic rather than heavy. If vapour quality matters more than raw efficiency, the TEMPEST 2 wins.
Learning Curve and Everyday Use
The M7 is the simpler device: heat to the click, draw, done. The VapCap system gives instant audio feedback. Most beginners can use the M7 productively within a few minutes.
The TEMPEST 2 takes longer to dial in — you need a feel for the right heating time and airflow. The upside: once mastered, you have more control over vapour character through ball choice, bowl size, and airflow.
Which One Is Right for You?

Pick the DynaVap M7 if: You are new to butane vaping, want a reliable click system, and plan to explore the enormous DynaVap accessory ecosystem. The M7 is the gold standard entry point under €100.
Pick the TEMPEST 2 if: You want desktop vapour quality in a pocket device and are willing to invest time in the technique. The TEMPEST 2 suits experienced users who know what pure convection means in practice.
Frequently Asked Questions
Which produces denser vapour?
Depends on the goal. The M7 delivers dense, compact vapour in a few hits. The TEMPEST 2 produces more flavour-forward vapour across more draws — denser than most convection portables, but the M7 extracts more mass from the material through conduction.
Can I use both with an induction heater?
Yes, both. The M7 is compatible with the DynaVap Orion and any standard induction heater for 8 mm stems. The TEMPEST 2 works with the iSpire Wand, YLL 3.0, Portside Mini, and similar models.
Is TEMPEST 2 accessory-compatible with DynaVap parts?
Yes. Both use the 8 mm stem standard. DynaVap glass stems, water pipe adapters, and mouthpieces fit the TEMPEST 2 directly. That is a real advantage compared to proprietary connectors.
Which is better for beginners?
The DynaVap M7. The click system removes the guesswork from heating. The TEMPEST 2 rewards users who can fine-tune their technique — better suited to experienced butane vape users who know what they want.
Which is better for microdosing?
The TEMPEST 2 has the edge. The adjustable bowl allows loads from ~0.05 g in the smallest position. The M7 bowl is fixed at ~0.1 g — it can be partially filled, but the setup is less flexible.
Conclusion
The M7 and TEMPEST 2 share an energy source and stem format, but little else. The M7 is the no-fuss everyday carry for anyone who wants butane vaping fast, reliably, and affordably. The click system takes the guesswork out entirely.
The TEMPEST 2 is a step up for users who want maximum quality from their material. Pure convection, adjustable bowl, desktop-level vapour — but at twice the price and with a real learning investment.
