The biggest practical difference is heating approach: G Pen Elite II runs hybrid (primarily 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.
G Pen Elite II uses hybrid (primarily 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.
G Pen Elite II has the larger chamber at 0.3 - 0.5 grams, 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.
Listed prices are close: $250 for the G Pen Elite II versus $247 for the Tempest. Day-to-day price will likely come down to whichever retailer is running a promotion.
G Pen Elite II controls heat with digital control, while the Tempest uses manual. G Pen Elite II gives you finer per-degree control.
G Pen Elite II's spec sheet lists ~1 hour of use; the Tempest lists N/A. The two manufacturers measure battery life differently here, so direct comparison isn't straightforward.
Across the 24 specs we line up, they share 2 and differ on 22, an overlap of about 8%. The differences are concentrated in the areas the spec table highlights with a marker.
