Now with more building room and a larger tank capacity, the Gemini Mega RTA from Vaporesso returns the famous functions and features from it's smaller predecessor. Complete with a 4.5mL tank capacity and a 17mm build deck, user's now have more building room to play with and a longer vape time in between filling tanks via the quick and easy top fill method. Along with the Gemini Mega's large build deck, the post terminals have large 2mm post holes for tremendous flexibility to cater to all kinds of building styles whether it be a single coil or dual coil build. Dual air tubes feed directly into the center chamber to cover multiple angles for maximum vapor and flavor production with airflow that can be precisely adjusted at the bottom base of the unit. The liquid control function will allow users to accurately dial in how much liquid they want to feed into the wicks to control flooding and dry hits depending on the viscosity of the liquid. All of these features combined makes the Gemini Mega RTA a beautifully engineered affordable rebuildable tank system.
