So I bought my geni tank with my evod ego battery and used them together from the get go for about a month now. Last week I dropped my vape and couldn't vape it after that. I went home and changed my coil and it worked for about two hours and the same thing happened. No vape. My original tank that came with the battery still works just fine. So I changed the coil again and used my buddies battery and it worked until I put the tank back on my battery and then the tank stoped working again. Any suggestions?
