If your TV is within the wattage of the outlet, you'll be good. The built-in inverter will auto-shutoff if you exceed the wattage.
Maximum available capacity of the power outlet
■ While the vehicle is being driven
The maximum capacity of the power outlet is always 120 V AC/100W.
■ When the vehicle is stationary
The maximum capacity of the power outlet varies depending on
the position of the shift lever.
● The maximum capacity is 120 V AC/100 W when the shift lever
is in any position other than P or N.
● The maximum capacity is 120 V AC/400 W when the shift lever
is in P or N.
The maximum capacity of 400 W can only be restored by turning
the power outlet main switch off and then on again with the shift
lever in P or N.
