A complete observation from a non-technical person. I have only two devices... the istick and a Kamry X6 (which is an ego style VV battery, 1600mah). I actually vape a lot longer on the X6, 1600mah battery. The display on the istick must be a significant battery drain? Not complaining, as I can generally get a full day of vaping from the istick......just thought I'd get longer battery time than the 1600mah battery. Oh well, I'm generally pretty happy with it.
The battery capacity is usually measured to the lowest voltage the battery can go (usually 2.6v-2.75v). The Istick cuts off at 3.3v so while the battery might be a 2200mah rating, it's not using the full capacity (and it's not linear). The upside to this is that the battery will last much longer than if you drained down to 2.75v.
about Rock Bottom Vapes. I've ordered a few things from them recently, and they have been stellar regarding all facets of my orders. Great prices, quick shipping, and so far excellent customer service. $34 for the iStick from them is well worth the money for as good as most of you have been commenting on the capabilities of the iStick. If I hadn't already blown my vape budget for this month, I'd probably be getting one myself
