TV \ Inverter

[Zug]

Hey guys new here just pick up our new Rockwood Roo, I have everything set up for dry camping but the one thing I can't figure out is the TV the trailer came with a 22" LCD TV and i got a 100w inverter you just plug in to the cig plug in the wall. My problem is it will run the TV fine then for no reason the TV shuts down the just flash's green like its trying to power back up but can't I also tried another inverter a bit older but did the same thing. I only want to use this inverter to run the TV from time to time but I can't seem to find anything on the net that describes what my TV is doing.

Anyone have any thought?

What is power consumption of the TV? If it is even close to 100w the inverter probably can't handle it. Is your inverter a pure sin wave or a modified sin wave model? Some electronics units don't handle modified sin waves very well.

Are you sure nothing else is running besides the TV?

This is a "power gear" bought at Home Depot it does say 100W

The 22"in my Roo is 50W and I plan on trying my 100W inverter. I'm not sure how good a sine wave would be from a small wattage inverter, but I've been planning this for days, so I'll try it out and let you know how it goes.

I'm not sure that that's a cigarette lighter. Probably a power port. A cigarette lighter will carry about 15 amps. A power port only 5 amps without over heating. If the OP is running the inverter with a 50w 120volt draw, the 12 volt wall port/plug will see 4.8 amps at 100% efficiency. My guess is that he's having voltage problems due to excessive heat. It could be the inverter is problematic or just responding to the erratic voltage.

Interesting. I thought the power ports handled 10+ amps. Maybe running a separate line, with heavier gauge wire and 10A fuse. Auto head lamps draw about 10A, so the wire shouldn't need to be too heavy. If the current draw by the inverter is too much, the power outlet fuse should have blown.

fuse may or may not blow. I found my tv amp & power port fused at 15amps. The socket says 5 amp max. Nothing else is on that fuse.

Wire size for 10 amp and 20' would be #14 to keep voltage loss at <3%.
