The biggest practical difference is heating approach: G Pen Pro runs convection while XMAX V3 Pro runs hybrid (primarily convection). 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 $110 for the XMAX V3 Pro, about $20 less. Live retailer pricing can shift, so confirm before buying.
XMAX V3 Pro reaches session-ready temperature in 15-30 seconds, while the G Pen Pro takes ~30 seconds. That's roughly 8 seconds quicker on the XMAX V3 Pro, which is useful if you want shorter, on-demand sessions.
G Pen Pro uses convection heating, while the XMAX V3 Pro uses hybrid (primarily convection). 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 XMAX V3 Pro. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
XMAX V3 Pro uses 18650 (user replaceable), so you can carry spares for back-to-back days. The G Pen Pro has a built-in battery you can't swap on the go.
G Pen Pro controls heat with modular - 3 stages, while the XMAX V3 Pro uses digital (precise). XMAX V3 Pro gives you finer per-degree control.
