Most e-cigarettes have 3 main parts – the battery, the atomizer/flavor filter, and the cartridge. There’s also the standard battery charger. The cartridges should last for about 20 cigarettes. The battery will last for approximately one day with normal use, however with most starter kits, you receive 2 batteries, so you can always have one charged, while using the other. Manufacturers recommend that you do not use this kind of e-cigarette in a vertical position, since liquid could leak.
A newer line of e-cigs, (technically referred to as the e-8 or e-9 models) has only 2 parts – a battery and a cartridge, sometimes referred to as a cartomizer, which contains the atomizer. These models typically produce more vapor and less bacteria. They are not refillable, but then there’s no leakage or liquid mess. Cartomizers last longer than the 3-part cartridge – equivalent to about 30-40 cigarettes. Batteries last about 4-6 hours depending on the size and your usage, but again, starter kits give you 2 batteries, so you can always have one charged, while using the other.
Keep in mind, you’ll have to replace the atomizer in a 3-part e-cig when it gets clogged (anywhere from a few week to a few months); The battery in all e-cigarettes need to be replaced eventually, but you can recharge them for months before they wear out. They certainly have longer lives than the atomizers.
All this aside, I truly believe e-cigarette companies are on to a good thing. It’s about time someone took on big tobacco (and more recently the FDA) with an alternative cigarette that:
– Doesn’t contain the 4000 carcinogens of traditional cigarettes
– Eliminates second-hand smoke
– Offers tobacco smokers a satisfying alternative to traditional cigarettes
