Oh, I've done that before, plenty of times. Letitia (spelling finally correct

) is correct, most battery mods have reverse battery protection. The only thing that happened was the mod wouldn't turn on, I'd briefly have fears I broke it, only to feel relieved and stupid once I figured it out.
I am kind of glad I wasn't
vaping during the time that Mech mods were the best real option. My absent-mindedness coupled with quitting effects, would probably have caused something dreadful.
It usually happens if I'm just waking up and it's kinda dark, my husband has this irrational thing about turning on lights at 5 a.m., he hates it. I'm an early awakener, so I've taken to checking out my mod's battery and juice situation before bed. It's really hard to handle in the dark and I've had several minor catastrophes.
