The biggest practical difference is heating approach: G Pen Pro runs convection while Session Odyssey runs conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
Session Odyssey is the cheaper option at $50 compared with $90 for the G Pen Pro, about $40 less. Live retailer pricing can shift, so confirm before buying.
G Pen Pro uses convection heating, while the Session Odyssey uses conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
G Pen Pro has the larger chamber at ~0.25 grams, versus Up to ~0.2g on the Session Odyssey. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
Session Odyssey fully charges in ~1 hour, ahead of <3 hours on the G Pen Pro.
Session Odyssey charges over USB-C; the G Pen Pro uses a Micro-USB port. USB-C means one fewer cable to keep around if your phone and laptop already use it.
Across the 21 specs we line up, they share 4 and differ on 17, an overlap of about 19%. The differences are concentrated in the areas the spec table highlights with a marker.
