DynaVap make a vaporiser with no battery, no screen and no charging cable. It’s a metal pen, you heat the tip with a flame or an induction coil, and a little bimetallic cap clicks when it’s ready. Click, draw, click again when it cools. That’s the whole thing. People in Australia went looking for them because they’re cheap, they’re nearly unbreakable, and the flavour out of a properly heated DynaVap embarrasses a lot of gear that costs ten times as much.
There’s a knack to it, and that puts some people off. But once it clicks, so to speak, it’s hard to go back. Here’s the range, the honest version.
The “M”
The M is the entry point and the one most people should start with. It’s an all-metal vaporizer, mostly conduction with a bit of convection as you draw air across the hot tip. Stainless steel body, a knurled “grip ring” you spin to dial flavour-versus-clouds, and that signature click to tell you it’s up to temp. Portable, obviously. It fits in a pocket and weighs nothing.
The quirk is that it gets hot, properly hot, right where your fingers want to go. You learn to hold it by the right end quick smart. Heat the cap until the first click, let it settle a couple of seconds, then draw slow. One click forward gives you flavour around the 165-185°C mark, two or three clicks of heat pushes it past 200°C for bigger, denser hits. The M gets reissued most years with tiny tweaks, but any of them does the job.
The “B”
The B is the stripped-back, budget M. Same heating, same tip, same click, in a lighter body with a moulded grip instead of the metal one and a simpler finish. It’s the cheapest way into the brand and it’s a genuinely good vape, not a toy.
Who’s it for? Someone who wants to try the whole flame-heated idea without spending much, or someone who keeps losing things and wants a spare for the car or the festival. The trade-off versus the M is mostly feel and adjustability. The B is a touch less precise to fine-tune, and the lighter body doesn’t hold heat quite the same. Same temperature window though, roughly 165-205°C depending on how hard you heat it.
The Omni
The Omni is the top of the range and the one for fiddlers. It keeps the conduction-led heating but adds two things the others don’t: a fully adjustable airflow dial and an adjustable tip that lets you set a precise temperature stop. So instead of counting clicks and guessing, you can lock in roughly where you want to be and repeat it. Still a portable, still flame or induction heated, just a lot more control.
It’s the priciest DynaVap and the heaviest, and honestly most people don’t need that level of adjustment. But if you like dialling things in, or you chase low-temp flavour around 170-180°C and want it the same every single time, the Omni’s the pick. Bonus: it comes apart further for cleaning than the others.
Induction heaters
Not a vape, the thing that heats the vape. An induction heater is a desktop (or chunky portable) box with a coil inside. You drop the tip in, the coil heats the metal, you pull it out when it clicks. No flame, no butane taste, dead consistent heating, and you can do it one-handed without juggling a torch. Plenty are battery-powered so they’re not strictly bench-only, but most people park one at home.
The catch is cost and size. A good induction heater can run dearer than the DynaVap it heats, and a cheap one will heat unevenly or struggle to reach temp. Match the coil to your cap, give it the right number of seconds, and it’s the most pleasant way to run any of these pens.
Living with one
This is where DynaVaps earn the cult following. There’s almost nothing to break. You pull the cap and tip off, drop the metal bits in iso for a soak, give the stem a poke with a pipe cleaner, and it’s done. The O-rings are a wear part, they dry out and go loose every several months, so you swap them for a few cents rather than binning anything. No firmware, no battery to swell, no screen to crack. Look after the seals and a DynaVap genuinely lasts years.
One warning specific to flame heating: don’t cook it red hot. Over-torching scorches the herb and, over time, can discolour the tip. Heat to the click, not past it.
Which one suits you
Quick version. Want the classic all-rounder that does everything: the M. Want the cheapest way in, or a knockabout spare: the B. Want airflow and temperature control to fiddle with: the Omni. Sick of torches and want clean, repeatable heating at home: add an induction heater.
