The G Pen Hyer is a portable e-nail: a 6,000mAh battery pack, a full quartz tank, and a 14mm glass adapter that turns whatever water piece you already own into an electric rig. No torch, no desk, no rebuilding your setup around it.
Where It Comes From
Grenco Science has built G Pen hardware for well over a decade, and the Hyer is the portable e-nail end of that catalog. It sits above the pocket-sized Micro+ and alongside dry herb devices like the Dash II, with the full G Pen lineup covering the rest.
What It Actually Does
Smart heating holds a constant temperature output rather than spiking and dropping, which is the whole point of an e-nail over a torch. The concentrates tank pairs a custom-stamped stainless steel heating element with a full quartz chamber and an internal up-stem, giving the material maximum surface area and efficient airflow.
The tank cap is anodized aluminum with a built-in ceramic liner and dual airflow holes, attached magnetically with rotary action so you can adjust airflow mid-dab. The included stainless steel wax tool clips to the top or side of that cap instead of rolling loose in your bag.
Power and Setup
A 6,000mAh rechargeable lithium-ion cell sits in a lightweight anodized aluminum casing and charges over USB-C with pass-through, so you can run it plugged in. A braided power cable with snap-in magnetic ends connects the battery to the tank housing.
Operation is three buttons and a five-LED interface. Tanks thread in and out of the housing, and the quartz tank is rated for a minimum of 200 power cycles before it is worth replacing. A dry herb tank is sold separately if you want both materials.

Where to Get One
