The style design is very cool, looks like rocket
510 thread, the same as Vmax thread, you can use all kinds of 510 atomizer or cartomizer

You can use 18350/18650 or 18500 battery, all are ok, and only one battery in the tube, very safe
As for the function, it's full output of the battery voltage, no PCB, and there will be no problem even when you put wrong of positive and negative terminals of the battery.
There is a pulley at the bottom of the tube, it can make the switch of the battery locked automatically when the pulley is down, so it will not work automaticlally when you put it in your pocket.
