@extinctsnakes@mastodon.social I can recommend my vape if that helps any; it does make visible vapor but it's not like a "leet trixxx hi-temp v8p3" thing, it just.. heats stuff up so you can inhale it, and works, is reasonably priced & hasn't broken on us.
(A lot of the amt of/visibility of exhalation also depends on what you wanna vape, mind- Different liquids make more/less clouds)
@extinctsnakes@mastodon.social the 'big cloud' brands tend to run thick, too; they have wider barrels (so that + the higher temp means you inhale more at once)
So generally if something's big & bulky it's probably for showing off like that, with a high voltage core and large diameter inhalation. tube- Pen sized ones will have less emmissions simply by not having that hi-voltage & wide-diameter breathing tube capacity
