The biggest practical difference is heating approach: G Pen Pro runs convection while Vapman Classic runs conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
G Pen Pro is the cheaper option at $90 compared with $150 for the Vapman Classic, about $60 less. Live retailer pricing can shift, so confirm before buying.
G Pen Pro uses convection heating, while the Vapman Classic 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 ~0.1g - 0.15g on the Vapman Classic. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
G Pen Pro controls heat with modular - 3 stages, while the Vapman Classic uses manual. Both let you change temperature, just with different levels of precision.
Vapman Classic is the better fit for microdosing in our database, typically thanks to a smaller chamber, finer temperature control, or both.
