Comparison FAQs
What is the biggest difference between the G Pen Hyer and the Tempest?
The biggest practical difference is heating approach: G Pen Hyer runs conduction 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 G Pen Hyer and the Tempest?
G Pen Hyer uses conduction 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 G Pen Hyer or the Tempest hold more flower?
G Pen Hyer has the larger chamber at ~0.5g, 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 G Pen Hyer or the Tempest?
Listed prices are close: $250 for the G Pen Hyer versus $247 for the Tempest. Day-to-day price will likely come down to whichever retailer is running a promotion.
Can I set custom temperatures on the G Pen Hyer or the Tempest?
G Pen Hyer controls heat with digital control - 5 stage modular, while the Tempest uses manual. G Pen Hyer gives you finer per-degree control.
