The biggest practical difference is heating approach: G Pen Connect runs conduction while XMAX V3 Pro runs hybrid (primarily convection). That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
XMAX V3 Pro is the cheaper option at $110 compared with $180 for the G Pen Connect, about $70 less. Live retailer pricing can shift, so confirm before buying.
G Pen Connect uses conduction 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.
XMAX V3 Pro uses 18650 (user replaceable), 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.
G Pen Connect's spec sheet lists 10-15 sessions; the XMAX V3 Pro lists 30-45 minutes or 5-6 sessions. The two manufacturers measure battery life differently here, so direct comparison isn't straightforward.
XMAX V3 Pro covers 100 - 220C (212 - 428F), 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.
XMAX V3 Pro charges over USB-C; the G Pen Connect uses a Micro-USB port. USB-C means one fewer cable to keep around if your phone and laptop already use it.
