Comparison FAQs
What is the biggest difference between the Firefly 2+ and the Tempest?
The biggest practical difference is heating approach: Firefly 2+ runs convection while Tempest runs convection-heavy with some conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
What's the difference in heating between the Firefly 2+ and the Tempest?
Firefly 2+ uses convection heating, while the Tempest uses convection-heavy with some conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
Does the Firefly 2+ or the Tempest hold more flower?
Firefly 2+ has the larger chamber at ~0.15g, versus 0.075g - 0.15g on the Tempest. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
Which is cheaper, the Firefly 2+ or the Tempest?
Listed prices are close: $250 for the Firefly 2+ versus $247 for the Tempest. Day-to-day price will likely come down to whichever retailer is running a promotion.
Can I swap the batteries on the Firefly 2+ or the Tempest?
Firefly 2+ uses removable (proprietary), so you can carry spares for back-to-back days. The Tempest has a built-in battery you can't swap on the go.
Can I set custom temperatures on the Firefly 2+ or the Tempest?
Firefly 2+ controls heat with digital (precise), while the Tempest uses manual. Firefly 2+ gives you finer per-degree control.
What battery life can I expect from the Firefly 2+ and the Tempest?
Firefly 2+'s spec sheet lists <90 minutes; the Tempest lists N/A. The two manufacturers measure battery life differently here, so direct comparison isn't straightforward.
