I was wondering also ,,, should i go with the mini or the regular? I vape hard, but i already have a .... load of 18350 batteries.
I
think the AW IMR 18350's are rated at 700mah. For reference, on a normal work day I vape about 1300-1600mah per day (about 12 hours from door to door),so I go through a little more than 100mah per hour. 2-18350's might last me the day until i get home, but it would be close. Everyone's vaping level is different, and a lot depends on what voltage and resistance you are using. For me, that's 3.8-4.0 volts at 2.0 ohms (I don't use my Provari at work).
Short(er) version: If you're a heavy vaper, you should figure on going through 3 18350's a day at a guess, and maybe getting into a 4th. You'll need a charger with you, or you will need to carry 3-4 batts along for the day. This is especially true if you're vaping at a higher wattage than me (7-8 watts)
Mind you, all of this is semi-educated guesswork!
