If you are in a place where you can have access to electric, you can just switch one battery out and have another charging, so its no big deal. If you work at a place where you can't charge, it might be better to get something with a better battery. You can also get chargers for your car and personal chargers and USB passthrus to help with all of that. Cig easy has a new Elite that has a longer lasting battery. It has gotten some good reviews here.
If you are going to order a Volt, do it soon, because right now they have a 21% code- only good for a couple more days. I have a Volt and I like it. The Volt has cartomizers instead of the carts/attys that the Vogue has. I would recommend a manual battery, since filling cartos can get messy and you can ruin the automatic batteries if you get juice in them. I also got a T-Rexx on deep discount and like that even better.
Now, if I could just find an e-liquid that I like!
Its all very confusing, but peeps here are very helpful. Good luck with your choice.
also, I am a closet vaper, but when everyone is gone during the day, I vape almost constantly, so maybe 6 hrs is not that much.
