Hi I just made the switch recently and I like most started with kind of a beat set up. I got the amigo mini sub kit and after having a whole pack of 5 bad coils I gave up on the atty and got a kanger top tank nano which I do like. The problem is I vape pretty hard throughout the day and the 1500mah pen style battery that came with the amigo kit isn't up to the task. I want to get into a box mod but still want something small and portable that I can wear in my pocket at work without a noticeable amount of gear. I am looking at the Joye cuboid mini 80w and the eleaf istick pico. Would both of these be compatible with my kanger top tank nano atty? Would I want to keep using the .5ohm SSOCC coils or switch to something else? What settings do I use on either of those? Thanks for any pointers its kind of information overload at first. I'm open to other mods but those are the two I seem to be drawn to at the moment.
