Im using an ipv 3 li on power mode at 30w. I recently got the kanger and it will vape maybe 2 or 3 times before it stops working and says check atomizer. I have used every one of the coils it came with and I get the same results with each of them. I dont know whether to just go buy another one or if there is anything else I can do to save it before I throw it out the window!!! Please help asap!!!
