Several surplus electronics companies sell very small hi-volt power supplies called
"fluorescent lamp inverters" or CCFL drivers.
In fact, these devices
are actually solid-state continuous-wave "CW" Tesla Coils:
they produce one or two kilo-volts at high frequency."
PDS: Apparently, CCFL's -- would seem to be analogous to being the "Raspberry Pi" (low end, cheap, affordable, etc.) -- of Tesla Coils...
Since 2005, hobbyists started making cigarette lighters from these.
Then someone started actually marketing them. Then someone else came up with a switched, double-arc version with a little "X"-shaped discharge, "Plasmatic(tm)."
Now everybody gotta get their own, apparently. Not five dollars though.
