Hi vapors. im eggert. Im a noob n new in this vaping world. I have read a lot about it n still not quite sure bout it. My questions are: 1: is it safe to vape on my mod which im using 50w mini flask mod. Im not sure if it regulated mod or not, with samsung battery inr 18650 25r 3.7v 2500mah li ion rechargeable. Also using kanger tech sub mini tank with 0.5 sub ohm which fluctuates a bit 0.4 and currently sits at 0.38. 2: why it jump? Is it screw loose issue? Im still on the pre made coil from kanger btw. I have tighten the screw and loosen up my wick as tutorial from utube. Haha maybe im wrong cos im really not quite sure a bit. Pls do help me on this n 3rd question if i increase my watt is it ok as long i dont go beyond my battery voltage of 3.7v?. Im really worried if i do it wrong way n my mod will be a time bomb like i read some article..advance thks n happy vapping. Cheers ps; english is not my language pardon me if it bad.
