The biggest practical difference is form factor: these aren't the same kind of device. G Pen Pro is a portable, Stache Terp Tap is a desktop. Pick based on whether you want something portable or something stationary.
G Pen Pro is the cheaper option at $90 compared with $180 for the Stache Terp Tap, about $90 less. Live retailer pricing can shift, so confirm before buying.
G Pen Pro uses convection heating, while the Stache Terp Tap uses conduction (510 thread cartridge or screw-in coil). Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
G Pen Pro is the take-anywhere choice. It's a portable, battery-powered unit, while the Stache Terp Tap is built for home use, where bigger heaters, AC power, and larger chambers make sense.
G Pen Pro controls heat with modular - 3 stages, while the Stache Terp Tap uses 6 voltage settings: 2.5v, 2.8v, 3.1v, 3.4v, 3.7v, 4.0v. Both let you change temperature, just with different levels of precision.
Stache Terp Tap 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.
