If you don’t want to know anything about safety or you can’t wrap your head around it all, by all means, get a very good quality charger (as well as a good quality mod) and good quality batteries with spare sets and charge all your batteries in the external charger.
Oh! I definitely want to know what’s the safest way of doing it., all things considered, that’s why i’m reading these posts pretty closely and digesting the info. Some of the advice is contradictory isn’t it? And that’s why I like closely-reasoned posts like yours. That enables me to make sense of the contradictions, and pull out the stuff that’s most relevant to me
Ofc,anybody who wants to be completely safe should switch off their power supply , and go back to a more primitive way of living, shouldn’t they? Electricity is dangerous stuff, and vaping gear gets way more than it’s fair share of bad press in that regard. I’m not about to get paranoid about it!
