I suppose the opposite is true too: you could make a little circuit in volume that could turn junk (or any) batteries into firestarters. Glad nobody seems to have made these IFDs.
Not knowing anything about vape internals and with him referring to them as “lithium” instead of LiPo or LiIon, I thought on first reading that he was recommending recharging primary lithium batteries. Which would already be a kind of stochastic IFD!
I'm assuming IFD stands for "Idiotic F##K#NG Devices", right?
