I'm going through an 18350 battery each hour. 2 came with my epipe, the other two are efest. I use a trustfire charger. They are all about a month old. How are people getting 6 hours? I'm a chain vaper. I never put it down unless eating a meal except dessert is good vaping time also. i only sleep 4hrs a day
) Should I buy more/different batteries? I have innokin SVD (kinda junkie quality) and RSST at 2.0ohms. Hub says I need a desktop plug in device! lol
