How we compare the shop's current options
The comparison above covers four dry-herb devices listed in our Shopify catalogue. Prices and sale availability are read from their live listings when you open this guide; checkout remains authoritative. Features come from those product listings, with each product linked for the full specification. These are specification-based buying suggestions, not hands-on test results or an independent ranking of every device sold in the UK.
A powered VENTY and a battery-free DynaVap solve different needs. Choose electronic control if setting a temperature on the device matters most; consider external heating if avoiding battery charging matters more. Battery-free does not mean ready to use without a compatible heat source. Check what is included before budgeting.
1. Heating style: convection, conduction or hybrid
Convection devices pass hot air through the material; conduction devices heat through contact with the chamber. Hybrid designs combine both. The VENTY manufacturer describes its mini-heater as a combination of convection and conduction. DynaVap's cap-heated devices use an external heat source and a manual heating cycle, so they are a different ownership experience. Do not assume a heating label alone tells you whether a device is on-demand or session-based. See our Dry Herb Vaporisers Explained guide for the underlying terms.
2. Temperature control: electronic setting or heated cap
The VENTY has an on-device temperature display and adjustment across its published 40°C–210°C range, with Booster and Superbooster functions. DynaVap devices do not offer the same electronic temperature selection: the cap is heated externally and its click indicates the heating cycle. Choose the control method you are comfortable using; do not compare the numbers as if they were equivalent controls.
3. Heat-up time, power and what you need
Storz & Bickel lists a 20-second heat-up for the VENTY. DynaVap's official instructions describe heating the cap with a suitable torch and waiting for its click; actual timing depends on the heat source and technique, so a direct seconds-based comparison would be misleading. Include the cost and availability of a compatible heat source when comparing a battery-free device.
4. Chamber size and airflow: compare like with like
The manufacturers list different nominal bowl capacities: approximately 0.25 g for HyperDyn, 0.1 g for M7 and 0.075 g for The B. These are model specifications, not a recommendation about how much anyone should use. The M7 can reduce its bowl size by half; The B has a fixed half-bowl design. HyperDyn offers seven airflow settings and 10 mm / 14 mm tapers. Check the exact product listing for included adapters and accessories.
5. Build quality, warranty and spare parts
Compare the actual materials and replaceable parts, not just the brand name. The manufacturer describes HyperDyn as titanium and the M7 tip as stainless steel; The B combines a silicone stem with a stainless-steel tip. Storz & Bickel states a two-year statutory warranty with an optional additional one-year limited warranty for eligible registered products, subject to its terms. DynaVap publishes model-specific warranty information; check the current terms for the exact device and seller before purchase.
Which of these four designs should you shortlist?
Shortlist the VENTY if you want electronic temperature control, a powered device and adjustable airflow. Shortlist HyperDyn if you prefer a battery-free titanium device with a larger stated bowl and adjustable airflow. Consider M7 if you want stainless steel and a bowl that can be reduced by half. Consider The B if a smaller fixed half-bowl and silicone stem are the priority. These are feature-based starting points, not a performance ranking.
A benchmark: the Storz & Bickel VENTY
As a reference point for a premium portable, Storz & Bickel's published specifications for the VENTY list a 20-second heat-up, hybrid convection and conduction heating, precise control from 40°C to 210°C, adjustable airflow up to 20 L/min, USB-C Supercharge (about 80% in 40 minutes) and a 2-year warranty extended by 1 year on registration. Read our full Storz & Bickel VENTY Guide for the details.
Portable shortlist
A portable is a device you can carry. The four-way comparison above is portable. So are the Mighty+, PAX Four, PAX Mini 2, PAX Flow, the Arizer Air and Solo portables, Go SRT, Tinymight 2, the G Pen Dash models, and the XMAX portables linked below. Desktops such as the Volcano Classic, Volcano Hybrid, Plenty, Arizer Extreme Q and V-Tower stay on a table and plug in. Use the Volcano comparison if you are choosing between those two.
Read each listing for heat-up, battery and what is in the box. This page does not repeat a specification it has not taken from that listing.
A first device
If you want buttons and a temperature you can see, start with a powered portable and the how-to-use guide, not a torch-heated DynaVap. The DynaVap hub explains why those need a separate flame. If you want fewer settings, the smaller PAX and XMAX listings are in the catalogue. They are not ranked. Open two listings and compare the controls you are willing to learn.
Smaller electronic portables
XMAX V4 Pro, XMAX V3 Nano, XMAX Starry V4, XMAX OONT Pro, Wolkenkraft, Flowermate, Smono and Weecke are all listed as their own devices. The V4 Pro listing describes convection heating, 100–220°C in 1°C steps, session and on-demand modes, and a replaceable 18650 battery. The V3 Pro device is not a separate listing. A replacement 18650 battery listing says it fits the V3 Pro and the V4 Pro. Do not read that battery as the vaporiser.
Prices change. The product page is the price. This guide does not sort the range into under a set amount.
What is included, and what must be checked separately
Storz & Bickel's VENTY technical overview lists the powered device, concise instructions, a filling-chamber tool, a USB-C cable, spare seals and screens, and a cleaning brush. A charger plug is not listed in that manufacturer's standard pack. The manufacturer also states that VENTY is for dry herbs, not for tobacco, tobacco products or nicotine; follow the exact device's suitability instructions.
DynaVap's HyperDyn manufacturer page lists a Hyper dosing capsule and a tin case alongside the device components. Its M 7 product page lists a tin case and an unfilled single-flame DynaTorch. These are manufacturers' published pack lists, not a promise about every retailer bundle. The B's accessories, and any replacement cap, charger, lighter or cleaning part, must be checked on the specific Joint Venture product page before purchase.
Quick buying checklist
Before you buy, check:
- Heating style matches how you'll use it (on-demand vs continuous)
- Exact temperature control, ideally in single-degree steps
- Powered model: charging port and battery type; battery-free model: compatible heat source
- Chamber size and airflow suit how you'll use it
- Manufacturer warranty, spare parts and a UK seller
