So a friend of mine recently gave me his Sigelei mod to help me quit smoking. I need to get a new tank for it and am not quite sure what to get. I've had some experience in the past with vaping and love the taste and clouds that come with high wattage tanks. I've been looking at the Smok TFV8 cloud beast, but I can't seem to find anything confirming that it's compatible with my mod. I've seen that the 510 connector needs to be a specific size and am not sure if my Fuchai fits that standard. Should I get the TFV8 or something else entirely?
