G Pen by Grenco Science at Evertree, the latest Dash 2 dry herb vaporizer, the Dash+ flagship, the Hydout 510 cartridge battery, and the Melt hot knife loading tool, all in UK stock.
G Pen is the Los Angeles brand that did more than anyone to make portable vaporizers feel like part of music, art and lifestyle culture rather than a piece of consumer hardware. The Snoop Dogg collaboration in 2013 was a turning point not just for G Pen but for how the entire portable vape category was positioned. Twelve years on, the company continues to put out products that are accessible in price, easy to use, and designed to fit into a real day rather than sit in a drawer. Evertree stocks the current UK G Pen range.
G Pen is the consumer brand of Grenco Science, Inc., founded in Los Angeles in December 2011 and trading by 2012. The company was started by Chris Folkerts (CEO), Anthony Barron and Anthony Marino. The very first batch of 15,000 units shipped without “Gio” printed on the packaging despite that being the planned name, customers started calling them G Pens, and the name stuck.
The brand’s defining moment came in 2013 when Snoop Dogg partnered with the company on a co-branded edition. That single collaboration moved G Pen from a vape brand into a cultural brand, and it set the template for how Grenco has positioned itself ever since: products are built to be accessible, the marketing leans into music, art and street culture, and the design language has more in common with consumer tech accessories than medical equipment. Subsequent collabs with Wiz Khalifa, Berner and others have continued that approach.
G Pen leans accessible where premium vaporizer brands lean technical. The pricing is closer to consumer-electronics impulse-buy than enthusiast-tier investment, the interfaces are deliberately simple, and the form factors are designed for actual day-to-day use, in pockets, in bags, on the way out the door. You can pick a G Pen up and use it in under a minute without reading a manual, and the brand has stayed consistent on that approach across more than a decade of products.
The second distinctive is range breadth. Grenco builds devices across nearly every category in portable vaporization, dry herb, 510 cartridge batteries, electronic dab rigs, electric loading tools, and accessory hardware. That’s unusual. Most vape brands specialise in one or two categories. G Pen carries the whole spectrum, which means it’s often the brand to look at when you want a single ecosystem covering different consumption methods rather than buying from three different manufacturers.
Four current G Pen products are in UK stock at Evertree right now, covering four different use cases: the latest entry-level dry herb portable (Dash 2), the upgraded flagship dry herb portable (Dash+), a 510 cartridge battery, and an electric loading tool. Click any model name to jump to its product page.
The Dash 2 is the newest dry herb portable in the G Pen range and a meaningful upgrade over the original Dash across every spec the original was criticised for. The chamber is now a 0.4g ceramic oven (larger than the original), the display is an OLED with precise temperature control rather than fixed presets, and the device finally moves from Micro USB to USB-C with pass-through charging support. The 1100mAh battery is bigger too.
The temperature range runs 188°C to 220°C (370°F to 428°F), adjustable to specific degrees via the OLED interface with haptic feedback confirming inputs. Heat-up time is around 30 seconds. A built-in pick tool tucks into the body for convenient on-the-go loading and cleaning. The session timer defaults to 3 minutes but can be modified through the device menu. At 97 x 35 x 21mm and 62g, it’s one of the most pocketable serious dry herb vapes in this price bracket.
The Dash+ is G Pen’s premium dry herb portable and a meaningful step up from the Dash 2 for users who want stronger build quality and more sophisticated heating. It uses a hybrid convection-and-conduction heating system built around a full titanium chamber (rather than the Dash 2’s ceramic), reaching vaporization temperature in around 20 seconds. The 1800mAh battery is one of the largest in this size class, and the 0.3g titanium chamber delivers a clean, flavourful session.
The interface is more sophisticated than the Dash 2: three buttons, a full-colour LED display, and haptic feedback give you precise control over temperature and session settings. Dual clean-air intake channels and a magnetic mouthpiece with a spiral ceramic airpath are engineered to keep the draw smooth and the vapour cool. For users who want a refined G Pen dry herb portable with proper technical chops and a more sophisticated heating system, the Dash+ is the right pick over the Dash 2.
The Hydout is G Pen’s 510-thread cartridge battery and one of the most discreet-by-design devices in this category. The standout feature is a hidden magnetic mouthpiece cover that conceals the cartridge when not in use and protects the oil inside from light degradation. At 90 x 37.5 x 18.5mm, it’s small enough to disappear into a pocket without obvious bulk.
Voltage control is more granular than most 510 batteries. Five voltage levels (2.4V, 2.8V, 3.2V, 3.6V, 3.8V) are selectable via triple-click and shown on a bright LED display, letting you tune for either flavour (lower voltages) or vapour output (higher voltages) depending on the cartridge and the oil. A 10-second preheat mode at 1.8V helps unclog thick oils before a session. USB-C charging completes a full charge in around an hour. Compatible with most 510-thread cartridges up to 2g, both ceramic and metal-tipped.
The Melt is an electric loading tool for concentrates and is, by G Pen’s measure, the smallest hot knife on the market at just 100mm tall, 13mm wide and 6mm deep. The slim anodised aluminium body is small enough to live in any pocket or kit bag, and a protective cap covers the heated tip during transport so nothing else in your bag gets warmed by accident.
Operation is one-button. Press to heat the ceramic tip to 150°C (302°F), which is the temperature at which most concentrates slide off cleanly without sticking or burning. The 500mAh rechargeable battery is topped up via USB-C with pass-through charging supported, so you can use the tool while it’s plugged in. Works with any dab rig, e-rig or vaporizer chamber including non-G-Pen devices, making it a useful accessory for anyone who works with concentrates regularly.
The four G Pen products at Evertree each cover a different use case rather than competing with each other. Quick reference:

The four G Pen products at Evertree don’t really compete with each other, each one solves a different problem.
If you vape dry herb and want the newest, most pocketable G Pen with precise temperature control, the Dash 2 is the entry-level pick. OLED display, 0.4g ceramic chamber, USB-C with pass-through, and a properly small form factor.
If you want a more premium dry herb experience with a titanium build and more sophisticated heating, step up to the Dash+. The hybrid heating, 0.3g titanium chamber, larger 1800mAh battery and full-colour LED display make it the more refined session vape.
If you use 510-thread cartridges for oils and concentrates, the Hydout is the right battery to put them in. The voltage adjustability and the magnetic mouthpiece cover are the two features that set it apart from most 510 batteries on the market.
If you work with concentrates regularly and you’re tired of fighting with cold dab tools, the Melt is the accessory that makes loading easier. It’s a useful addition to any concentrate setup, including non-G-Pen devices.
Many users buy two or more of these together, the Dash 2 or Dash+ for dry herb days, the Hydout for cartridge days, and the Melt for any time concentrates are involved. The four products form a small but coherent G Pen kit for users who consume in multiple ways.

They’re the same company. Grenco Science, Inc. is the legal company name. G Pen is the consumer brand the company sells products under. The G Pen name was actually a happy accident, the first batch of products were meant to be called “Gio” but shipped without the name on the packaging, customers called them G Pens, and the name stuck. The company has used G Pen as its main product brand ever since.
G Pen is the consumer brand of Grenco Science, a Los Angeles company founded in late 2011 by Chris Folkerts, Anthony Barron and Anthony Marino. The brand became culturally significant in 2013 through a high-profile Snoop Dogg partnership and has continued to lean into music and culture collaborations since.
The Dash 2 is the newest entry-level dry herb portable. Smaller (62g), 0.4g ceramic chamber, 1100mAh battery, OLED display with precise degree-by-degree temperature control, USB-C with pass-through. The Dash+ is the premium step-up. 0.3g titanium chamber, 1800mAh battery, hybrid convection-and-conduction heating, full-colour LED display, 20-second heat-up. Pick the Dash 2 for pocketability, the newest tech, and the slightly larger 0.4g ceramic chamber; pick the Dash+ for titanium build, hybrid heating and the more sophisticated display.
G Pen sits at the more accessible end of the portable vaporizer market in terms of price, while keeping engineering features (titanium chambers on the Dash+, ceramic on the Dash 2, hybrid heating, USB-C charging, app-free interfaces) that compare favourably to more premium-branded devices. The brand is genuinely well-regarded for value and for the breadth of categories it covers, dry herb, 510 cartridges, electronic dab rigs, and accessories.
The Hydout is compatible with most 510-thread cartridges up to 2g capacity, both ceramic and metal-tipped designs intended for oil concentrates. Five adjustable voltage levels let you tune the device for different cartridges and oils, with lower voltages favouring flavour and higher voltages producing more vapour.
Yes. The Melt is designed to work with any rig, e-rig or vaporizer chamber. It’s an electric loading tool, the only thing it touches is the concentrate being placed into a chamber, so brand compatibility isn’t a factor. It pairs equally well with a G Pen device, a Puffco Peak, or a traditional dab rig.
The 1100mAh battery in the Dash 2 is a meaningful upgrade over the original Dash, supporting around 4 to 6 sessions per charge depending on temperature and session length. USB-C pass-through charging means you can also use the device while it’s plugged in if the battery does run low mid-day.
Yes. Both the Dash+ and Dash 2 come with a 2-year limited warranty. The Hydout and Melt each carry a 90-day limited warranty. Warranty claims can be handled through Evertree or directly through G Pen at gpen.com/pages/warranty.
Yes. All G Pen orders are dispatched from our UK warehouse via Royal Mail tracked 48-hour service. A paid next-day upgrade is selectable at checkout if needed.
