I'm a hardcore smoker of 30+ yrs and recently switched to vaping. I have a REVOLUTION which works great, but want to piece together a setup to better suit my needs. I'm on the road alot and frequently work long days so I need a portable charge system and batteries with long life. I really enjoy the simplicity of the 2 pc REV and prefer to stay with that. I dont care to get into all the mods and upgrades at this time. The MEGA battery sounds perfect for me but does it fit the 510 cartomizers? With an adapter? Can I get a pass-through charger for the mega? What about a car charger? I'm considering buying the 510 cartomizer Express Kit just to have the extra manual & automatic batteries on hand in my car just for emergencies. Will all these things fit/work together? I'm hoping to build a simple, no-nonsense grand-slam heavy-hitter that is powerful & dependable with the longest battery life possible and back up parts as well. I would really appreciate advice from those of you who are knowledgable on this. Thanx a million!
