AIO pen-style vaping device using SMOK RPM coils is called the SMOK Stick R22 AIO Kit. It has an adjustable airflow function and a power function with six settings. A built-in 2000mAh battery powers the SMOK Stick R22 Kit and will easily last all day before needing to be recharged via the Type-C connection. Match the associated tank with a reliable and balanced output. The device is activated by a simple, useful button, which improves use by removing the need for menu systems. When it is time to recharge, LED lights incorporated in the fire button denote varied operational conditions. The power output of the SMOK Stick R22 can be changed from the bottom up and by turning the device's base, it can emit up to 40W of electricity. There are 6 power levels with a 10W starting point, a 5W adjustment every time, and a 40W maximum. Threads are used to attach the top tank to the apparatus. On top of the battery is where you'll find the rotating, double-slotted airflow ring that isn't removable. You can customize the airflow holes using the middle adjustable airflow. Unscrew the thread top cap in a counterclockwise direction, fill the tank from the top, and then screw it back on. Additionally, there are two monitoring windows on either side of the tank. Included in the kit is an RPM Mesh 0.4ohm coil, which gives you more vapor.
