Not sure if im posting in the right area or not. I bought the istick mini 75w. it didnt come w a battery, so the first thing i did was plug it in using the usb port, it came with its own tank put the tank on that it came with, got the atomizer short error, changed coils. Used 4 different tanks that i own and i know work with other mods and still got the same atomizer short error, lifted up the pin on the mod, tried screwing in the tank all the way and then slowing unscrewed the tank to see if there is any connection, tried just about everything i have read on the internet about why atomizer would be short.. So I was sent another istick pico because maybe the 1st one was faulty, still received same error. Maybe this is a NOOB question but could it be that there isnt a battery inside the mod( even though it is plugged in by usb) i just wanted to see if it worked prior to buying a battery. If the istick is plugged in using the usb charger will it work, I guess is the real question?
