The Keen Mechanical Tube Mod is a collaboration between Timesvape and TenaciousTXVapes. This newly released tube is powered by a single 21700, 20700 or 18650 battery. Since this device is fully mechanical, we do highly recommend understanding ohms law and battery safety.
Also, it does have a hybrid 510, so atomizers with a protruding 510 pin can only be used with it. With that being said, there's quite a few new features to this mechanical device that makes it unique and a hard hitter.
