The G-pen connect is super handy as it converts conventional glass water pipes into a bonafide e-rig. Ideal if you have a bunch of paraphernalia and not willing to buy a whole new system. The G Pen Connect easily vaporizes concentrates and connects to any standard 14mm glassonglass water pipe connection.
Note that due to ceramic heating elements the device heats in a matter of seconds. Despite the small size, it still features temperature control like its bigger colleagues. As a berry on the cake, there come reverse airflow technology, a magnetic tank cap for easy loading, a spring-loaded carb, and an extended draw mode for the most steady pot heads.
To wrap it up, small size combined with 850 mAh battery and functionality make it a reliable portable option.
