some people prefer the convenience of a disposable device
I don't understand this. Instead of plugging it into a charger, they'd rather go to the store to buy another, or more likely order online and wait for it to be delivered?
I introduced a battery charger to a group of people that used disposable vapes and the knowhow to charge them. It changed the way they interacted with the vapes completely even saying funny high ideas like "we should patent this".
i don't have personal experience with this, but i imagine so, because if you plug your vape into a charger, you can smoke it in an hour or two, and if you buy a cigarette at the convenience store that's a block away, you can smoke it in two minutes
maybe you live somewhere without convenience stores
