Hi all, New to vaping but already loving it. I was a cigarette smoker for about 20 years, then quit for 5 years and then picked up a Pipe and started smoking that. Big mistake. It took a few years Before I got to ridiculous levels of smoking the pipe (5-6) large bowls a day but decided to quit and try vaping. I bought from a local shop because I like to try to support local shops when I can. My starting equipment was a kanger protank 3 and a gravity 1300 mah variable voltage battery (3.2-4.8) the shop mixes Mr e liquids right there and have tried 5-6 flavors and have liked them all. I already bought another protank 3 to switch flavors. Okay so now for the questions. I'm already thinking about a new battery/mod. I think I would like a bit more voltage as I enjoy a good throat hit. Also not sure what kind of quality the gravity battery is. Are there any recommendations for a good battery that isn't huge(not looking at a box mod yet) And next question I like to change flavors a bit and will be getting another tank soon but fit the meantime when I switch flavors if there is any left in the tank is it s bad idea to poor e juice back out of it into a container? Thanks for any help.
