I bought an ipv 1 35 watt box mod about a week ago and a Kanger Subtank to use on it. I also had to order a new battery which took an extra couple of days. When I finally got everything together and ready to go, I filled up the subtank with some juice and tried firing it up. Of course with my luck the mod decided to just shut off. Since I'm new to vaping, I'm not sure if this is a problem with the mod or with the subtank. Has anyone else had any similar problems. Any and all help is appreciated, thanks.
