Here is a my learned opinion, the biggest drawback e-cigarettes have are - the batteries.
Every wonder why many experienced PV users tend to go for the bigger batteries, like the AW 18650, 2600mAh battery? It is because those will last a couple days on a single charge. That is what I use, and since I am using a 2.0 Ω atty and it is a 3.7V battery, it runs at (nominally) 1.85 amps (Current=Voltage/Resistance), or 1850 milliamps (1 amp = 1000 milliamps), thus giving me 1.40 hours (2600mAh/1850mA=1.40h) of
ON time, and 1.4 hours is a lot of vaping when a drag is about 3-7 seconds. That works out to between 720 and 1680 drags.
I know newbies want a PV that looks and feels like a cigarette, I did as well. Ever wonder why the Joye 510 has a poor reputation for battery life (180mAh)? 3V, at 3 Ω, equals 1 amp or 1000 milliamps which gives you .18 hours (180mAh/1000mA = 0.18h) of
ON time. That is just over 10 minutes or roughly between 92 and 216 drags. For the record, most 510 attys are lower than 3 Ω, which shortens the life of the battery even more.
Sure, people new to vaping should start with an inexpensive PV, if you like vaping but are frustrated with battery life (time between charges as well as overall life, running those little e-cig batteries at this capacity kills them quickly) please know there is better out there. My wife tried vaping and just didn't like it at all, I'm glad she didn't waste money buying a high dollar mod. I love vaping so I spent the money to get something that was actually
EASIER. I fill a 3ml bottle in the morning, pop in a fresh 18650 battery, and vape all day without changing carts, cartomizers, juice, or batteries. The only drawback is searching for the holy grail of juices, I enjoyed that journey as well, and settled on Honey Flue Nut, 555, Applewood Tobacco, and RY4, all of which I can vape for days on end. It don't get much easier than that.
That and I find the wooden box mod, specifically the Phidias, is quite a thing of beauty.
But hey, it's just my OPINION... along with some facts.
YMMV,
