Grenco Science, known for its innovative vaporization devices, introduces the G Pen Dash, a compact and highly portable dry herb vaporizer. While some of their wax vaporizers have received mixed reviews, this travel-friendly device shows real promise. Let’s find out whether it truly stands out among its competitors.
How It Works

Before using, fully charge your G Pen Dash. This portable vaporizer operates much like most other dry herb vaporizers. Here’s a quick guide:
- Step 1: Remove the mouthpiece and load your herbs into the chamber.
- Step 2: Reattach the mouthpiece and press the button five times to power on the device.
- Step 3: Press the button three times to cycle through the three temperature settings.
- Step 4: The device will begin heating automatically.
- Step 5: Once the device vibrates, you’re ready to take a hit.
For better vapor production and extraction, let the heating chamber run for a few extra seconds after the vibration signal.
Temperature Flexibility
The G Pen Dash offers three temperature settings, each indicated by a different LED color:
- Blue: 375°F (190°C)
- Green: 401°F (205°C)
- Red: 428°F (220°C)
These settings provide a good temperature range, giving users options for both lower and higher heat levels.

Vapor Quality
The G Pen Dash delivers decent vapor for its size. Although the short vapor path causes the device to heat up—especially at higher temperatures—it doesn’t become overly harsh. The stainless steel chamber with a glass glaze helps maintain consistent vapor quality, particularly at lower heat settings. However, the use of plastic in the mouthpiece and airpath slightly detracts from the overall experience.

Although it’s a budget-friendly device, other affordable vaporizers can deliver better vapor quality than the Dash. It heats up in about 20 seconds, and for optimal results, letting it heat for a few extra seconds improves performance. The side air vents also allow for a smooth and unrestricted draw.
Build Quality
The G Pen Dash offers decent build quality for a budget vaporizer, though there’s still room for improvement. It has a solid look and feel and doesn’t appear cheap at first glance. While higher-quality materials could have been used for the vapor path, Grenco has included several standout features that add value — such as haptic feedback, a glass-glazed stainless steel chamber, and a quick 20-second heat-up time.
Additionally, the pass-through charging feature allows you to use the device while it’s charging — a convenient bonus at this price point.
Battery Life
The G Pen Dash comes with a built-in 950mAh battery, providing about 8–10 sessions per charge, which is quite reasonable. The front LED indicators show the battery status as follows:
- 3 LEDs: 80–100%
- 2 LEDs: 60–66%
- 1 LED: 30–33%

Portability and Discreetness
The G Pen Dash is highly portable — compact enough to fit comfortably in your hand, making it ideal for quick, discreet sessions while on the go. It’s recommended to use a portable charger for extended use away from home. The pass-through charging feature adds extra convenience, especially when an outlet is available. Its small size and moderate vapor output make it perfect for private, short sessions without drawing unwanted attention.

Ease of Use
The G Pen Dash is very easy to operate, with simple button controls — five clicks to power on or off, and three clicks to change temperature settings. The LED indicators are intuitive and user-friendly, even for beginners. The mouthpiece attaches and detaches easily with light pressure and stays firmly in place. It also comes with a keychain tool for packing and emptying the chamber. Regular cleaning is recommended to maintain optimal performance.
Overall Experience
The G Pen Dash offers solid value for its price. While it doesn’t quite match the vapor quality of the Venty or the battery life of the Mighty, it’s still a reliable portable option. Key highlights include the glass-glazed stainless steel chamber, magnetic mouthpiece, pass-through charging, and compact design. However, the battery life could be better, and the vapor can get a bit harsh at higher temperatures, which is a common drawback for devices of this size.
