02The models in detail
The Convectum is our powerhouse: pure soft-Z convection, powerful heating, and rich, dense vapor. Together with the Stilus Pro Max, it delivers the best flavor in our range. If you're looking for uncompromising performance, prefer to enjoy your sessions at home, and value a robust, stable device, the Convectum is the right choice. It's conveniently operated via a display with precise temperature control (80–220 °C), and the replaceable 18650 battery ensures you can refuel on the go.
The Stilus Pro Max is our best-selling model and the flagship of the Stilus range. Its XXL chamber holds the most material – ideal for long sessions or evenings spent together. Combined with the Convectum, it delivers the best aroma in the range. It also features pure Soft-Z convection, precise temperature control (80–220 °C), and a replaceable 18650 battery, allowing you to easily refuel on the go. This is the most well-rounded package.
The Stilus Pro Convection is our all-rounder for everyday use – essentially the predecessor to the Stilus Pro Max, only with a slightly smaller chamber. It delivers the same gentle Soft-Z convection in a slim, handy format, fits perfectly in the hand, and fits in any jacket pocket. If you're looking for a well-balanced convection oven for everyday use and don't need the extra-large chamber, you can't go wrong with this one.
The Nanu is an entry-level model like the Stilus Mini – but it offers several advantages: gentle Soft-Z convection instead of conduction, a replaceable battery, and a display for precise temperature selection. Despite its compact housing, its large chamber holds as much as the Convectum and Pro Max. Ideal if you want an affordable entry point without sacrificing convection and convenience.
The Nanu x Vaporizer 3000 is technically and visually identical to the Nanu – the same Soft-Z convection, the same compact size, the same replaceable battery, and the same display. The only difference is the limited Openmind edition, created in collaboration with Simon Ruane. It's the right choice if you want this specific edition. As with any limited edition, once it's gone, it's gone.
The Stilus Mini is our entry-level model and the only device in our comparison that uses conduction. The chamber wall is heated directly, making it exceptionally quick to heat up and producing noticeably dense vapor clouds. With fixed heat settings, operation is intentionally kept simple: switch it on, select the setting, and you're good to go. This offers you the most affordable way into the world of vaporization – ideal if you want to find out if a vaporizer is right for you.
03Direct comparison: model against model
Many purchasing decisions ultimately come down to a duel between two similar devices. Here we directly compare the three most common pairs – so you can immediately see which one suits you best.
Convectum vs. Stilus Pro Max – Power or Capacity?
Convectum 169 €
Maximum heating power, abundant steam, convenient display operation. Designed for uncompromising performance.
Stilus Pro Max 149 €
XXL chamber for larger ink capacity, slim pen format. The more convenient all-around package.
In short: If you want the most powerful device with a display, choose the Convectum. If you value a large e-liquid capacity and a slim pen design, the Stilus Pro Max is the more compact choice – and even cheaper. Both use the same replaceable 18650 battery.
Stilus Pro Max vs. Stilus Pro Convection – XXL or slim?
Stilus Pro Max 149 €
XXL heating chamber for long sessions – our bestseller and the flagship of the Stilus range.
Stilus Pro Convection 139 €
The well-balanced all-rounder with a smaller chamber – essentially the predecessor to the Pro Max.
In short: Same soft-Z convection, same pen format, same replaceable 18650 battery. The difference is the chamber: If you want a larger e-liquid capacity for longer sessions, choose the Stilus Pro Max. If the smaller chamber is sufficient and you want to save €10, the Stilus Pro Convection is the right all-rounder.
Stilus Mini vs. Nanu – the two newcomers
Stilus Mini 94,90 €
Conduction heating, fixed heat settings, under €100. Fastest to start, even in dense clouds.
Nanu 119,90 €
For around €25 more, you get convection, a display and a replaceable battery – more comfort and a larger chamber.
In short: Both are entry-level models. The Stilus Mini is the cheapest way to try out a vaporizer at all. Those who want convection, a display, and a replaceable battery from the start should invest the extra €25 or so in the Nanu.

05Frequently asked questions about choosing the right HEAT vaporizer
Which HEAT vaporizer is best suited for beginners?
Both of these budget-friendly models are entry-level devices. For the lowest entry price, the Stilus Mini (€94,90) is the top choice: conduction heating, easy to use, and under €100. If you want to start directly with convection heating, the Nanu (€119,90) is the best alternative – also an entry-level model, but with Soft-Z convection, a display, and a replaceable battery.
What is the difference between conduction and convection?
With conduction heating, the chamber wall is heated directly – this is fast and produces dense vapor. With convection heating, hot air flows through the material, resulting in more even and gentler heating and a clearer aroma. The Stilus Mini uses conduction heating, while all other models use convection heating.
Which HEAT vaporizer has the largest chamber?
The Stilus Pro Max's XXL chamber holds the most material. The Convectum and Nanu also have the same large chamber – all three use the same dosing capsules. The Stilus Pro Convection and the Stilus Mini have a smaller chamber.
06Conclusion: The right vaporizer for every type
Whether you're looking for maximum performance with the Convectum, our best-selling flagship Stilus Pro Max with its XXL chamber, the all-rounder Stilus Pro Convection, the compact entry-level Nanu (with convection) and Stilus Mini, or the limited-edition Nanu x Vaporizer 3000: there's a suitable device for every need and budget – developed in Germany since 2014. Take your time to look at all the models and find your favorite.
