The biggest practical difference is heating approach: Firefly 2+ runs convection while G Pen Connect runs conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
G Pen Connect is the cheaper option at $180 compared with $250 for the Firefly 2+, about $70 less. Live retailer pricing can shift, so confirm before buying.
Firefly 2+ uses convection heating, while the G Pen Connect uses conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
Firefly 2+ uses removable (proprietary), so you can carry spares for back-to-back days. The G Pen Connect has a built-in battery you can't swap on the go.
Firefly 2+ fully charges in ~45 minutes, ahead of ~2 hours on the G Pen Connect.
Firefly 2+'s spec sheet lists <90 minutes; the G Pen Connect lists 10-15 sessions. The two manufacturers measure battery life differently here, so direct comparison isn't straightforward.
Firefly 2+ covers 93°C - 260°C, a wider band than the G Pen Connect at 180°C - 220°C (356°F - 428°F). A wider range gives you more room to dial in flavor at the low end and big clouds at the top.
