Genuine question here, has there been regulated devices causing injury I ask because I mainly avoid reports of this and that blowing up because between user error (most common cause) and various makers playing shenanigans to damage a competitor most are just attention grabbers with little truth or substance to them. On the issue of 2 battery 200w mods I look at them as an advert game everyone wanting to look as good as each other even though two currently available 18650's cannot safely deliver 200w continuous output it's a slimy practice but hardly limited to vaping. Also it cannot be ignored that the vast majority of user's buy 200w mods not because they are ever going to use even close to 200w but for the extended battery life that gives a true working day amount of vaping.
