The Authentic Hugo Squeezer BF Squonk Mod is a handy squonker that comes with a 10ml built-in silicone bottle that makes it convenient to use without refilling frequently. The Squeezer consists of a Nylon fibre shell, a gold plated 510 connector and special copper contacts. The mod is powered by a single 20700 / 18650 (18650 adapter needed, batteries not included). This kit includes a N RDA with a 25mm diameter and adjustable side airflow. It works well with not only the Hugo Squeezer BF Squonk Mod, but also with other squonk mods on the market. The RDA comes with a wide bore drip tip and a bottom feeder pin.
