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.
Current prices: TEMPEST 2 from ~€173 and DynaVap M7 from ~€85 in our price comparison.
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
The M7 (hybrid) preserves terpenes noticeably better below 190 °C, heating material only when you inhale. The TEMPEST 2 (convection) produces visible vapor from the first draw with any technique. Heat-up: TEMPEST 2 15s vs. M7 7s.
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.

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.

Frequently Asked Questions
Preisverlauf
Daily Use and Practicality
In everyday use, heat-up time shapes your routine more than any spec sheet suggests. The M7 reaches operating temperature in 7 seconds, while the TEMPEST 2 needs 15 seconds. That difference adds up over weeks of daily sessions. Quick morning sessions before work favor the faster device; relaxed evening sessions make the gap irrelevant.
Consider your typical usage pattern. If you vaporize 3-5 times daily, a few seconds per session compound into meaningful time savings. If you have one session per evening, both devices serve equally well. The M7 rewards impulsive, grab-and-go use. The TEMPEST 2 rewards users who plan their sessions.
Build Quality and Materials
The TEMPEST 2: Well-built device with solid materials.
The M7: Machined titanium and stainless steel built to last decades. DynaVap devices have no electronics, no batteries, and no parts that degrade over time. The precision-machined tip is the heart of the system. With basic care, a DynaVap can outlast any electronic vaporizer.
Water Pipe Compatibility
Both devices support water pipe use. Water filtration cools the vapor and makes higher temperatures more comfortable. WPA adapters (14mm and 18mm joints) are available for both the TEMPEST 2 and M7. Combining a vaporizer with glass elevates the experience significantly.
Cleaning and Maintenance
Regular cleaning directly affects vapor flavor and device longevity. Both the TEMPEST 2 and M7 benefit from weekly isopropyl alcohol soaks of removable parts. Screens and seals are consumable items that should be replaced every few months for optimal performance. A basic cleaning kit consisting of isopropyl alcohol (90 percent or higher), cotton swabs, and pipe cleaners covers most devices.
A clean device delivers noticeably better flavor than a neglected one. Most flavor complaints in online forums trace back to insufficient cleaning rather than device limitations. Residue buildup narrows the vapor path, increases draw resistance, and adds a stale taste. Budget 10 minutes per week for maintenance and both devices will perform at their best for years. Deep cleaning every 2-4 weeks prevents hard-to-remove buildup and keeps the airflow unrestricted.
Long-Term Value and Durability
A vaporizer is a long-term investment. Beyond the purchase price, consider replacement parts, cleaning supplies, and eventual battery degradation. The M7 has the longer warranty at 2 years versus 1 years for the TEMPEST 2.
The resale market for vaporizers is active. Well-maintained devices from reputable brands retain 50-70 percent of their original value after a year. Both the TEMPEST 2 and M7 hold their value well due to brand reputation and build quality. Buying a quality device upfront typically costs less than cycling through cheaper alternatives.
Community support also factors into long-term value. Devices with large user bases have better troubleshooting resources, aftermarket accessories, and replacement part availability. Both brands covered here have established communities that make ownership easier over the years.
