so I've been vaping on a vaporfi edge battery with vsix sub ohm tank for over a year. I tried using the kanger tech mini topbox but hated it. I'm currently looking into getting a box mod with two tanks one rdta and one sub ohm that i can both use on the same device. At the moment I'm considering a wismec rx2/3 with a geek vape tsunami and a smok tfv8 cloud beast. I'm new to all of this so am well aware I must take my time and learn about the ohm law and batteries. But I just can't seem to decide what to start with. Any advice would be really helpful and much appreciated. Thx for reading fellow vapers!
