Depends on coills And batteries mostly. Quality and materials used in mod are important as well. I get more then 30 hits from a single 18650 tube, so it should be more than that on a parallel box but I can talk about it since I don't use one. You can pull that info from steam engine for any specific built, it saves a lot of time and experimenting with different coill combos.How long can vape a tank on a mech? About 30 good hits?
