G Pen in the UK
G Pen is the hardware line from Grenco Science, a Los Angeles company that has been making portable vaporizers since 2012. The devices are simple to live with, one button, USB-C charging and a screen for temperature and battery, and nothing in the range costs more than £60.
What's in the range
Dash 2 dry herb vaporizer
The Dash 2 (£59.99) is G Pen's dry herb vaporizer. It has a 0.4g ceramic chamber, heats in about 30 seconds, and swaps the original Dash's three fixed presets for adjustable temperature control. The battery is up to 1100mAh and there's a loading tool built into the body. The six-month warranty extends to a year when you register it.
Hydout and 510 Original batteries
Both are 510 thread cart batteries that screw straight onto a standard oil cartridge. The Hydout (£29.99) has five voltage settings from 2.4V to 3.8V and a magnetic cover that hides the cartridge completely. The 510 Original (£19.99) has three settings and a smaller body. Both are 400mAh, charge over USB-C and fire either by drawing or by pressing the button.
Melt hot knife
The Melt (£28.99) is a loading tool, not something you inhale from. Its ceramic tip warms to 150°C in a few seconds so sticky concentrate lifts off cleanly into a banger, e-rig or vaporizer chamber. It works with any device, not just G Pen.
Who G Pen suits
Cartridge users who want a tidy battery without spending much, anyone curious about dry herb who doesn't want to commit £200 to find out, and concentrate users after a better loading tool. Three of the four products sit in our under £50 collection.
G Pen FAQs
Is G Pen a good brand?
For the money, yes. The range is well built and simple to use. It isn't in the same class as Storz & Bickel or TinyMight on vapour quality and doesn't pretend to be; it competes on price, size and ease of use.
Which G Pen battery should I buy?
The Hydout if you want finer heat control and the cartridge hidden, the 510 Original if you want the smallest, cheapest option. Both fit standard 510 thread cartridges.
Why is there no charging cable in the box?
G Pen ships every product in this range without one. All four charge over any USB-C cable and support pass-through charging, so you can use the device while it's plugged in.
Why buy from The Herbal Vaporizer Store?
Every G Pen we sell is genuine and covered by the manufacturer's UK warranty, with our own support if anything goes wrong. Orders over £25 ship free within the UK.
