I have no problem waiting a few hours. I was thinking about getting an extra battery and tank for a backup. I'm going to try things out for a week and then I'll see what i'll need.
This is good thinking friend. I am certain you will want another battery for back up.
My advice to you would be very gentle with your charger. I had problems with my beginner set up. I naturally went for a fairly cheap set up, not the cheapest but cheap, and I found that the battery chargers are poorly made, and that disturbing them(IE shoving in my pocket, putting into bags i would carry) damaged them quickly.
I would also advice you to have a back up ecig for emergencies if you other one were to break and you had to wait to purchase another. You will find that you can become very aggravated quickly, if your device were to break or malfunction, and not being able to vape.
