if your tv is 120v
then you either buy a small inverter or you buy a new 12v TV,
my choice is buy the inverter
but for one night, couldn't you read a book, watch movie on laptop, or other mobile device
call it an early night and get some sleep
these are options do NOT require the inverter, provided they have good charged batteries
I can explain it to you.
But I Can Not understand it for you !
