Very nice Niner, we can put that TV on the low power "list".
Hard to tell for sure, but it's a far cry from the 40 watts from the last unit. I am sure that the heat from the brick and the heat from the inverter, if I cut out the conversion from 12V to 120V then back to 14 or 12, what ever the out put of the brick... pretty sure I can do better with less load on the battery if I do a 12V direct battery to the TV and bypass the brick/converter.
I got about 2.85 amps on the positive cable with the TV/ converter and brick on, and about .25 amp with all the power supply and TV off, with 12.4V sitting in the battery. Will have to see what happens with 12v direct and re measure at the positive cable again with the DC clamp meter. At this point, spending $7 for a 12V plug and cigarette plug too, doesn't make good financial sense for the miniscule amps savings... More interested in cleaning up all the wiring behind the TV with something more clean and direct. Too much hanging around out of that silly 12V outlet jack.
Noticed that no matter what, that 12v brick sucks the amps, TV on or off.
