Thats good news ,most flat screen are 12volt though need constant 12volt to work properly hence the stabilizer in the 12volt lead ,simulare to what is in the mains lead ,without it the picture can fluctuate or damage the tv if goes much above 12volt,there lead is straight through so they must have confidence in there tvs .We are looking at the 16in 12volt lead £9.00 extra,a stabilized lead can cost between £30 and £50
