Heating & Temperature
The Connect uses conduction heating. Temperature goes up to 220 °C, heat-up takes roughly 5 seconds.
Conduction heats material through direct contact with the chamber walls. Fast heat-up and even extraction when the chamber is well-packed.
Battery & Charging
The Connect has a built-in 850 mAh battery. Passthrough charging works — you can use the device while it charges.
Design & Portability
The Connect is a portable vaporizer. It weighs 283 g — on the heavier side, but feels solid and well-built.
Accessories & Compatibility
The Connect works with:
- water pipe adapter (WPA, for cooler vapor)
Additional original accessories from G Pen are available separately.
Verdict
The Connect is a portable vaporizer by G Pen with conduction heating. It suits beginners and users looking for a straightforward device as well as bong users. Our price comparison shows it from €55.08 at 17 shops.
Using with a Bong
Place the Connect on a bong with 14mm or 18mm joint. Load concentrate into the quartz chamber and select temperature. Three levels available: low for flavor, high for clouds. Water filtration noticeably cools the vapor.
Chamber Types
Three chamber options: quartz for flavor, ceramic for even heat, and titanium for fast heat-up. Chambers swap tool-free — just pull out and insert.
App Integration and Smart Features
The DaVinci Connect pairs with the DaVinci app over Bluetooth, giving you full temperature control, session tracking, and oven diagnostics from your phone. You can set exact temperatures in single-degree increments between 149 °C and 221 °C, create custom Smart Paths that ramp temperature across a session, and monitor cumulative use to know when cleaning is due. The app also stores session history, which is helpful for dialling in your preferred settings over time. Bluetooth range is roughly 3 metres — enough for a coffee table but not a whole room.
Vapour Quality and Oven Design
The Connect uses a zirconia ceramic air path paired with a conduction-dominant oven that heats evenly from the walls inward. Oven capacity is roughly 0.3 g, which suits solo sessions and small groups. Flavour at lower temperatures around 175–185 °C is noticeably clean, thanks to the ceramic isolating the vapour from any metallic taste. Above 200 °C the vapour thickens and cloud production increases, though some terpene subtlety fades. The included flat mouthpiece keeps the profile pocket-friendly, and the optional glass stem adds a cooler draw for home use.
Battery and Charging
The Connect carries a sealed 3500 mAh battery that delivers around 8–10 sessions of 5 minutes each on a full charge. USB-C charging takes approximately 2.5 hours from flat. Pass-through charging is not supported, so you need to wait for some charge before starting a session. For heavy daily users, topping off the battery whenever you are near a charger is a practical habit. The auto shut-off activates after 5 minutes of inactivity, which preserves battery life during idle moments.
