The Tempest 2 beats the DynaVap HyperDyn, 9.0 to 8.5 overall, because it tastes better and draws easier. Its visual heat gauge also makes a good session simple to repeat, which matters a lot with a torch. Pick the HyperDyn if you want a bigger bowl, built-in water pipe tapers and DynaVap's parts ecosystem.
Key differences
- Heating: the Tempest 2 is convection-heavy, with zirconia balls storing heat in the cap. The HyperDyn is a conduction and convection hybrid.
- Heat feedback: the Tempest 2 adds a three-line visual gauge to its clicks. The HyperDyn relies on the click alone.
- Capacity: the HyperDyn holds 0.25 g. The Tempest 2 adjusts between 0.1 g, 0.15 g and 0.2 g.
- Dosing: the HyperDyn ships with a 0.125 g dosing capsule and takes concentrates. The Tempest 2 has neither.
- Draw: the Tempest 2 is wide open. The HyperDyn stays tighter, even on its most open airflow setting.
- Water pipes: the HyperDyn has 10 mm and 14 mm tapers built in. The Tempest 2 uses an adapter.
- Warranty: limited lifetime on the HyperDyn, one year on the Tempest 2.
- Price: $225 US list price for the Tempest 2, $229 for the HyperDyn.
Flavor and vapor: the Tempest 2's biggest lead
The Tempest 2 scores 9.6 for vapor quality against 9.0, and flavor is where that gap shows most. Hot air does most of the work here, fed by the heat stored in the zirconia balls inside the cap. In our sessions, that gave the cleanest flavor of any battery-free portable we've tested. At the default 0.15 g setting, one heat cycle cleared the whole chamber for us. Load it loose rather than packed, and move the screen to 0.2 g only once you have the gauge down.
The HyperDyn hits hard in its own way, with a 0.25 g bowl that throws thick clouds. Its heavy titanium cap holds heat between cycles, though you still reheat every 15 to 20 seconds of drawing. Heat near the crimp for flavor, or closer to the base for density at the cost of some terpene brightness. In our testing, the Tempest 2 still made the denser vapor of the two, despite its smaller bowl.
Draw and airflow
The Tempest 2 has startlingly low draw resistance for a torch vape, and even fully closed it pulls easier than most battery portables. You open it up by loosening the mouthpiece and rotating the heat shield over the air intake. The cap has its own airflow too. While everything is cool, loosen the top screw, turn the induction sleeve and retighten.
The HyperDyn gives you 7 airflow settings through the condenser depth, but even the most open one feels noticeably tighter than rival torch vapes. If you want a free, easy lung hit, that settles it in favor of the Tempest 2. If you like a restricted, cigar-style pull, the HyperDyn will feel right at home.
Learning curve and daily use
Neither vape is plug and play, and both need a torch or induction heater that you buy separately. On a torch, the HyperDyn is ready in about 8 seconds and the Tempest 2 in about 15. On a YLL 3.0, Mad Heaters starts the Tempest 2 at 80 watts for 35 to 40 seconds with the stock zirconia balls. The Tempest 2 scores 7.8 for ease against 7.0, and its three-line gauge is the reason. Stop at the same line each time and you get very similar draws, so we had it dialed in after 3 to 5 sessions.
The HyperDyn took us 5 to 10 sessions, because its click tells you it's ready but not how hot it is. The bigger Hyper Cap does forgive sloppy torch placement better than a standard DynaVap cap.
The Tempest 2's trade-off is cooldown, since its balls stay hot for several minutes after a session. The click won't reset until the cap cools, so quick back-to-back bowls take patience.
Heat sources, water pipes and carry
On induction, the Tempest 2 wins clearly. Mad Heaters confirms the YLL 3.0 and Ispire Wand, and the Tempest 2 ran better on induction in our testing. The HyperDyn's wider cap needs the right adapter, and on our Wand it gave wispier vapor, so we stuck with a torch.
For water pipes, the HyperDyn is the easier fit, because its tapers go straight into a 10 mm or 14 mm joint. Both slip into a pocket, and the HyperDyn edges portability 9.2 to 9.0 with its shorter 110 mm body. The Tempest 2 is the lighter of the two, though, at 46 g against 55 g.
Our best butane vaporizers ranking puts the Tempest 2 first, with the HyperDyn as our large-chamber DynaVap pick. If ball vapes are new to you, our ball vape explainer covers the basics before you buy.
What about the DynaVap M7?
If you searched Tempest 2 vs DynaVap with the classic model in mind, the DynaVap M7 scores 8.4 and has an $89 US list price, well under half the Tempest 2's $225. It weighs 33 g and holds 0.1 g, and it takes 1 to 3 heat cycles per bowl, where the Tempest 2 clears a 0.15 g bowl in one. Pick the M7 for a cheap, tiny first torch vape. Pick the Tempest 2 for flavor and one-cycle sessions. Our HyperDyn vs M7 comparison covers the DynaVap side.
