I was addressing the requirements for this particular person.
This particular person wants a PV that resembles a cigarette. Such product exists in KR808D-1 form. With a PCC that holds two batteries, even a heavy smoker will be fine for a 24-hour period. I know this from experience helping people get into vaping. I often hear people say "but you have to change batteries!". Yes, and you had to light a cigarette when you wanted one. Both acts take a few seconds.
There is no standard size battery out there that will last a day without being recharged, maybe a 510 mega can go 4 hours for me, but certainly not a day.
You mention the PCC. It's not only a good idea, it works very well and is in common use by a lot of long-time vapers. There are numerous styles and mAh-rating models available to suit just about anyone, and most are about the size of a pack of cigarettes...and you don't need a lighter.
Auto batteries will fail if they get juice inside, how will it help someone make the switch if it is dead?
A tiny amount of caution prevents juice damage to batteries, at least KR808D-1 batteries. If you visit any of the 808 sub-forums, you'll see very, very few complaints about dead batteries from juice intrusion.
Many people do caution against a slim battery because they are very limiting as far as vaping go. They do have the ability to help you make the switch, but you can't use LR atties or cartos on them for instance.
A person who's trying to quit analogs has very little concern about LR attys or cartos; they want something that emulates the smoking experience, provides smoke-like vapor and TH, and doses them with nicotine.
I was fine with my 510 Mega for about a month, but I found it lacking. We speak from experience with the slim batteries and we give the reasons why we are making these suggestions.
The 510 Mega is a 280 mAh unit at 3.2V. KR808D-1 batteries are available in the following:
65mm: 220 mAh
78mm: 320 mAh
102mm: 420 mAh
They run 4.2V off the charger, and settle in at 3.7V (other than Bloog's batteries, which are regulated at 3.6V).
I list these stats because, IMO, the 510 is an inefficient design for its size. 808 users are getting higher voltage and more mAh in the same sized unit.
I beg to differ, a PV that is reliable and doesn't require so much work is easier for someone making the switch.
There is nothing as simple and reliable as pre-filled cartos and auto batteries. I speak from experience. How complicated were cigarettes? Open the pack, grab one and light it.
Not very many people complain, "I bought an eGo, but it was too big and bulky and the battery lasted too long--so I went to a 510.
Okay, I'll be one. My first PV purchase was the first week of January. I bought a 510 kit and an eGo kit from Cignot on the same day. I went through LR attys, cart mods too numerous to mention, several hundred dollars worth of juices...I gave it a go.
I didn't stop smoking until I got my KR808D-1. I have a mini-PCC the size of an iPhone, four batteries and dozens of easily-refillable cartos. I'm very happy to be an ex-smoker with this PV.
I'm one of the people who needed the "cigarette-like" feel of a cig-style PV. Others are the same; the habit isn't just nicotine, it's that physical act of smoking. A cig-style PV provides that, is reliable and very easy to maintain. I'm hooked.
