Hi Judy & welcome to the forum. I also have a 510, and a lot of extra batteries and atty's, mainly bc with my 1st kit all 3 died within a month! So now I have lots of extra around just in case. I also went to HealthCabin and ordered some Mega Batteries, atty's & carts to try out. They are the same as the reguler 510 stuff but bigger & last longer(at least that's what I've heard, haven't tried them yet). To answer a few of your earlier questions: a PT=passthrough, this has a usb plug which allows you to hook directly to a computer so you don't have to worry about the battery dying I have one and love it! a PCC=Personal Charger Case, you can keep a battery charged as well as an extra atty & cartridges, so if your not near a plug you can keep this device charged and it will charge the batteries for you a few times. One question I have is what mg of e-liquid are you using? I started with 24mg, but it was a bit too much, so now I use 18mg most of the day & if I feel the need for more I always have some 24mg too. I would try different juices from other vendors, that's the only way to find one you like. Cignot has both VG & PG based e-liquid in different mg's. Do a search of the forums and see what kinds of e-liquid the forum members recommend. I hope this helps, PM me if you need to talk bc I too am fairly new and no one in my family smokes either. Good Luck to you, & just be happy with any progress you make with lowering the amount of analogues you smoke.
