Manufacturers don't put in underpowered 12v.
Says who?
Try it and see if it works. I have a 24" flat screen that draws about 65W and I powered it with a 150W inverter plugged into the cig outlet at the antenna booster. The TV would run OK if the batteries were at 100% (2-6v deep cycle), but if the batteries were less than 85% the low voltage alarm on the inverter would go off.
Reason was that the TT mfr ran 16 ga wire to the cig outlet..which is OK on a 10a fuse...but it was a good 20' from the TV to the converter distro panel. The wire size was creating voltage drop in the circuit so the inverter wouldn't work even when the batteries were still OK.
Solution was to move the inverter back by the converter, install a 15a transfer switch for the 120v circuit by the TV, and plug the TV into the 120v outlet.
