When a starter kit is described as disposable, are they referring to the cartomizer or the battery? I tried looking around but couldn't figure out what they meant. Thanks.
There are some disposable ecigarette kits.
madvapes, eg. has a 510 model that is considered disposable - 'at least 3 recharges of the battery' (some people, including myself have over 30 charges on them). There is a M400 series based disposable at heaven gifts. There is no charger for that one, when you run out, you run out. Then there are 'disposable' cartomizers - a cartridge and atomizer combo to where you're supposed to
throw them away after the cartridge part is depleted. However, people have ways of refilling cartomizers. See the boards for that.
Those are the types that I'm aware of and while I listed examples of where you could get some, there are other vendors that carry them as well. Just google 'disposable ecigarettes' and you'll get some hits.
