I have to disagree. I run my 22" Vizio LCD/LED TV and the separate DVD player from my 21 year old, 250 watt Statpower inverter. I plug the inverter's cigarette lighter plug into a dash outlet and run a 6' household extension cord up to the back of the TV - DVD player and "Voila" movies, as many as you like. While this means I am running off of the engine battery on a 6.8L V-10 there is more than enough capacity to handle such a small load.
LCD TV's, especially LCD - LED TV's don't draw squat and most simple DVD players are the same. While I prefer to draw from my house bank (2 group 27's), for DC loads (like my C-Pap), the house bank fed outlet I installed is located on the backside of the dinette and running the extension cord from the dash of our C is just a shorter/simpler connection.
Some of the more sensitive electronics (TV's, computers and C-Pap's to name a few), will caution against using anything less than pure sine wave. Be sure to read owners manual before hooking up to a non sine wave inverter. A Pure sine wave 300 watt, dual outlet inverter should set you back about $60. As far as wire size just look at the voltage drop charts and size your wire/in line fuses accordingly. For small loads and relatively short runs you will rarely, if ever, need more than 12 gauge.
IMHO: Lots of folks end up buying way more inverter than they actually need which is usually supported by way less battery power than the inverter needs. A simple stove top coffee pot will make your morning coffee and a small inverter will charge all of your phones, camera's, hearing aid's etc., as well as running the TV/DVD player and other misc electronic toys.
Works for me.
