The G Pen Dash II replaces the original G Pen Dash 5.4 at the same $49.95 price while fixing nearly every complaint. It adds an OLED display, precise temperature control, a larger 0.4 g ceramic chamber, and USB-C charging. For the sub-$50 bracket, those features were unheard of even a year ago.
The upgrades are real, but the Dash II still uses pure conduction heating in a compact chassis. That means vapor quality trails convection-based competitors that cost only slightly more. We tested it across the full 190-220°C range to find where Grenco's cheapest vaporizer earns its place on our portable rankings.
What's in the Box
Grenco Science keeps packaging minimal. You get the G Pen Dash II vaporizer with a built-in loading tool, plus a silicone mouthpiece sleeve for heat protection during longer sessions.
No USB-C charging cable is included. You supply your own, which most buyers already have.
Aluminum body at 62 g with OLED display
The Dash II measures roughly 97 x 35 x 21 mm and weighs 62 g, the same weight as the original Dash but in a slightly shorter, wider profile. The aluminum body feels solid for the price and fits comfortably in any pocket.
The magnetic mouthpiece detaches cleanly for loading and cleaning. A silicone sleeve wraps the mouthpiece tip for heat insulation during extended sessions. The mouthpiece includes a removable insert with an integrated vapor cooling path, a genuine improvement over the original Dash's uninsulated plastic mouthpiece.
The OLED display on the front shows current temperature and battery level in real time. This alone is a category-defining upgrade at this price. The original Dash relied on 3 color-coded LEDs that told you almost nothing.
