G Pen Vaporizers are portable vaping devices manufactured by Grenco Science, a Los Angeles-based company founded in 2012. They specialize in sleek, compact devices built for both dry herb and concentrate use — all at a price point that doesn't require you to sell a kidney.
Grenco Science built its reputation by collaborating with artists and celebrities, helping push vaporizers into mainstream culture. Today, the G Pen lineup spans everything from ultra-compact dry herb vapes to advanced concentrate rigs and water pipe adapters.
What separates G Pen from the crowd? Three things: build quality, accessibility, and variety. Most models heat up in 15–30 seconds, charge via USB-C, and are compact enough to fit in your pocket. For beginners especially, this combination is hard to beat.
What Are the Different G Pen Models Available?
The G Pen lineup covers dry herb, wax concentrates, and 510-thread cartridges. Here's a breakdown of the most popular models currently available:
Dry Herb
G Pen Dash II
Ultra-portable and beginner-friendly. Three preset temps, 850mAh battery, heats up in under 25 seconds. The go-to starter pick.
Dry Herb
G Pen Dash+
An upgrade on the Dash II with a larger oven and extended session mode. Great for solo or shared sessions on the go.
Dry Herb

Concentrate

Concentrate
G Pen Connect
Attaches directly to a water pipe via 510 connection. Heats to 450°F–900°F in seconds. Zero learning curve if you already own a rig.

How Do G Pen Dry Herb Vapes Work? Conduction vs. Convection Explained
Most G Pen dry herb vapes use conduction heating, where the herb sits directly against a heated ceramic or metal chamber wall. This approach heats up fast — typically within 15–30 seconds — and keeps the device simple with fewer moving parts.
The G Pen Elite II stands out by giving you precise temperature control, letting you dial in exactly how hot your session runs. Lower temps (around 356°F / 180°C) tend to preserve terpenes and produce a lighter, more flavorful vapor. Higher temps (above 400°F / 204°C) extract more cannabinoids and produce denser clouds.
For beginners using G Pen dry herb vapes, start at the lowest preset temperature and work your way up. You'll find your sweet spot within a few sessions — everyone's preference is a little different.
What Is the G Pen Vaporizer Price Range — Are They Worth the Money?
Honestly? Yes. G Pen hits a sweet spot between budget disposables and high-end desktop units. Entry-level models won't burn through your wallet, while the premium options still cost less than comparable competitors.

Which Is the Best G Pen Vaporizer for Different Types of Users?
There's no single "best" — it depends on your lifestyle, what you're vaping, and how often you use it. Here's how to match the right model to your needs:
🔰 Best for Complete Beginners — G Pen Dash II
Three preset temperatures, dead-simple one-button operation, and an 850mAh battery that charges via USB-C. It takes the guesswork out of your first vaping experience. The best G Pen vaporizer for most first-timers is, without question, the Dash II — affordable, reliable, and easy to clean.
🌿 Best Dry Herb Upgrade — G Pen Dash+ or Elite II
The G Pen Dash+ Dry Herb Vaporizer adds a larger herb chamber and improved session mode over the original Dash, making it great for slightly longer, more social sessions. The Elite II steps things up further with full precision temp control and a ceramic oven for the purists among us.
💨 Best for Concentrates — G Pen Roam
If wax or oil is your preference, the G Pen Roam is a portable powerhouse. It includes built-in water filtration (yes, seriously), a quartz atomizer, and a 6,000mAh battery — the biggest in the G Pen lineup. You get rig-quality vapor in a travel-friendly body.
🔌 Best for Rig Owners — G Pen Connect
Already have a water pipe you love? The G Pen Connect plugs in via a 510 thread and turns your existing glass into an e-nail setup. No combustion, no torch, no fuss. It's one of the smartest upgrades for concentrate users.
How Do You Use a G Pen Vaporizer? Step-by-Step for First-Timers
Getting started with a G Pen is straightforward. Here's a simple workflow for dry herb models — concentrate devices follow a similar pattern with slightly different loading steps.
Charge Fully Before First Use
Plug in via USB-C and wait until the LED indicator shows a full charge. First sessions on a dead battery are a classic beginner mistake — skip it.
Grind Your Herb to a Medium Consistency
Not too fine (it'll clog), not too chunky (it won't vaporize evenly). A medium grind fills the chamber without blocking airflow.
Pack the Chamber Snugly — Don't Over-Pack
Fill to just below the top and gently press down. Over-packing restricts airflow and gives you a weaker pull.
Power On and Select Temperature
Most G Pen models power on with 5 clicks. For preset-temp models, cycle through low, medium, or high. For Elite II, use the +/- buttons to dial in your exact temp.
Wait for the Heating Indicator, Then Inhale Slowly
The LED or display will signal when the device is at temp (usually 15–30 seconds). Draw slowly and steadily — quick puffs reduce vapor production on conduction devices.
Clean After Every Few Sessions
Use the included brush to clear the oven after it cools. A quick isopropyl alcohol wipe on the mouthpiece keeps everything tasting fresh. G Pen replacement parts and cleaning kits are widely available.
What Is the Battery Life Like on G Pen Devices?
G Pen battery capacity varies quite a bit depending on the model. The compact Dash II runs on an 850mAh cell — enough for roughly 4–6 sessions before you need to plug in. The G Pen Roam, built for heavier use, packs a 6,000mAh battery that can last all day without a charge.
· G Pen Dash II — 850mAh (approx. 4–6 sessions)
· G Pen Elite II — ~2,200mAh (approx. 8–12 sessions)
· G Pen Roam — 6,000mAh (all-day use with recharge via USB-C)
All current G Pen models use USB-C charging for fast, universal compatibility.
One standout feature: most G Pen devices support pass-through charging, meaning you can use them while plugged in. Handy if you're home and don't want to wait. The G Pen battery across all models is lithium-ion — expected lifespan is typically 300–500 full charge cycles before noticeable capacity degradation.
What G Pen Replacement Parts Do You Need and Where to Get Them?
Regular maintenance extends the life of any vaporizer significantly. The most commonly replaced G Pen parts include mouthpiece screens, chamber screens, coils (for concentrate models), and atomizer units for devices like the G Pen Connect and Roam.
Most G Pen devices come with spare screens in the box. When those run out, G Pen replacement parts are available directly through authorized retailers. Raven Route carries G Pen devices and can point you toward compatible accessories for your specific model.
G Pen Elite II Review: Is It Worth the Upgrade?
The G Pen Elite II is Grenco Science's flagship dry herb device, and it earns that title. The ceramic-lined oven heats evenly, the digital display makes temperature selection clear and precise, and the full-spectrum range (200°F–428°F) gives you real control over your session.
Vapor quality is noticeably better than the Dash-series models at lower temperatures — you can taste terpene profiles more clearly. Battery life is solid, and the device charges quickly via USB-C. For intermediate to advanced users who vape daily, this is a worthwhile investment.
The only genuine trade-off is size — it's slightly bulkier than the Dash II. If portability above all else is your priority, the Dash+ wins. If you want the best flavor and control the G Pen lineup has to offer in a dry herb unit, go Elite II.
G Pen Dash+ Review: Best Budget Dry Herb Vape?
The G Pen Dash+ sits in a sweet spot most beginners will appreciate: better than entry-level, priced like one. It builds on the original Dash with a larger herb chamber — so you load less frequently — and adds an improved session mode that maintains temperature more consistently across a full session.
Heating time clocks in around 20–25 seconds. Three temperature presets keep things simple. USB-C charging means one cable handles everything in your bag. For a first vape purchase or a budget-conscious upgrade, the Dash+ is hard to argue against.
