The Complete G Pen Vaporizers Collection
At Twelve Tribes, we carry every G Pen Vaporizer Grenco Science makes — dry herb vapes, concentrate dab pens, eRigs, and 510 thread batteries. Every unit ships with full manufacturer warranty, because we're an authorized retailer, not a gray-market reseller. Whether you're picking up your first device or adding a Connect to an existing glass setup, we can tell you exactly what to buy and why.
What We Carry
Three Ways to Vape. One Lineup.
Dry Herb Vapes
From $49.95
The G Pen Dash II is the benchmark under $50 — 0.4g ceramic chamber, OLED display, 30-second heat-up, and USB-C charging in a pocket-sized body. If you want more headroom, the G Pen Dash+ steps up to hybrid convection/conduction heating, a full titanium chamber, and an 1,800mAh battery that hits in 20 seconds flat. Both are designed for on-the-go sessions: easy to load, consistent from first draw to last, no combustion.
Shop Dry Herb Vapes →Concentrate & Dab Pens
From $49.95
G Pen's concentrate lineup runs from slim wax pen to full eRig. The G Pen Micro+ ($49.95) packs 850mAh and three temperature settings into one of the most portable dab pens on the market. The G Pen Connect attaches to any 14mm or 18mm water piece, turning your bong into a torchless rig. Want a self-contained all-in-one? The G Pen Roam ($149.95) has built-in water filtration and no exposed glass. At the top, the G Pen Hydout ($24.95) runs a 400mAh battery compatible with virtually any glass-on-glass setup — no torch, ever.
Shop Concentrate Vapes →510 Thread Batteries
From $12.95
Not every setup needs a dedicated device. The G Pen 510 Original and Hydout give you universal 510-thread compatibility starting at $12.95 — variable voltage, multiple colorways, and draw-activated or button-fire options depending on the model. If you already run cartridges or want a reliable backup, these deliver consistent performance without overcomplicating your kit.

FAQ
Common Questions
What is G Pen? +
G Pen is the vaporizer brand from Grenco Science, founded in 2012 and based in Los Angeles. They produce portable dry herb vaporizers, concentrate wax pens, eRigs, and 510 thread batteries — covering nearly every vaping use case across multiple price points, starting from $12.95.
What's the difference between G Pen dry herb and concentrate vapes? +
Dry herb vapes (Dash II, Dash+) heat ground botanical material using conduction or hybrid convection heating — no combustion, smoother vapor. Concentrate vapes (Micro+, Connect, Roam, Hydout) are purpose-built for wax, shatter, and other extracts using atomizer-style heating elements. The two categories use different chambers and are not interchangeable. Make sure you're buying for the material you actually use.
Is the G Pen Dash II good for beginners? +
Yes — the Dash II is one of the most beginner-friendly dry herb vaporizers at any price. The OLED display gives clear temperature feedback, the 0.4g ceramic chamber is easy to pack and clean, USB-C charging means no proprietary cables, and heat-up takes about 30 seconds. Controls are minimal by design, so there's a minimal learning curve.
How do I use a G Pen Connect vaporizer? +
Remove the water attachment cap, connect the G Pen Connect to your water piece's 14mm or 18mm joint, load concentrate into the ceramic cup atomizer, select your voltage setting via the color LED button, and inhale through your water piece. No torch needed. The 850mAh battery powers multiple sessions per charge, and three voltage settings let you dial in temperature to taste.
Does G Pen offer a warranty? +
Yes. Grenco Science backs G Pen devices with a limited manufacturer warranty against defects. When you purchase from Twelve Tribes as an authorized retailer, your warranty remains fully valid. Keep your proof of purchase and register your device on gpen.com if prompted after purchase.
Where can I buy G Pen vaporizers online? +
