Your other question was: "how long would a single xhale02 cart last."
According to the xhaleo2.com and e-hookah.com websites (which sell the XHALE O2): "Each cartridge will last you around 100 puffs." Such claims, however, usually are quite exaggerated. On the other hand, a cartridge can be refilled many, many times with
e-liquid. So what you really will need is not more cartridges, but
e-liquid.
I see those sites do not sell e-liquid. Virtually every other vaping supplier does however. There are so many good ones and so many different flavors. Since cost is always a primary criterion for me, a good starting point is candre23's
USA Liquid Suppliers - Cost Per ml + Shipping Chart. It is sortable by any of the five columns of information. The default is supplier name, but I suggest you switch it to "Sample bottle." [Later on, when you've determined your favorite flavors, you can use "Large bottle."]
As for Kurt's answer to your other question, I suspect that he is thinking of the
XHaler mod from NHaler, which indeed is a battery
case for the batteries contained therein.
However, you are referring to
this device. Right?
I'm not sure what model it is. I understand that it is being sold at 7/11s. I wondered whether it is an M402. That model is 96 mm and has an exposed female atomizer, as does the XHALE O2 (which e-hookah says is 9
5 mm, pretty close). But
psychler has said that the parts don't quite fit. He reports being impressed with the XHALE O2's battery (compared to the M40X or 510).
Interesting. This may be a case where we veterans know less about an e-cig model than newer members. Most of us (although not all) are more into mods, LR atomizers, and drip tips than super-minis, especially the new ones.
