Some vape pens use a heating element that sits inside the coil and comes into direct contact with the extracts in the bowl. The Surge by Pucker uses a superior design, where the heating element sits under the quartz bucket. So it never comes in direct contact with the extracts. It heats the quartz bowl, which heats the wax or oil. The Surge also allows you to control how much airflow you allow through the device with each hit. Simply turn the dial to open it up and use like a mini dab rig or close the airway for a classic vape pen experience. Featuring either manual or 15 second sesh-mode and auto shutoff, this little vape packs a big punch.
