Small inverter for TV

My cheap MSW would put lines on the screen. No trouble with GoPower SW.

Cheap inverters also tend to get hot. That wastes a lot of battery.

Op hasn't returned.

Brick also tends to run hot on MSW in my experience.
Some too hot to touch. More wasted energy.

You need 200-300W inverter because you might want to run something else, ex. laptop or MP4 video player at the same time.

Preferably PSW. $20 MSW may or may not work with TV, laptop and player could have problems too. They all get warm, and often have fans, so make sure yours is fan-less (unless installed where you can't hear it).

Preferably with dedicated 110V inverter outlet or powerbar close to TV and other electronics.

I would leave 12V to permanent 12V devices. For charging a phone via USB, you can get $1 adapter on Ebay https://www.ebay.com/itm/5V-USB-Car-Cigarette-Lighter-DC-Power-Charger-Car-Adapter-for-Iphone-Cell-Phone/382011298326?hash=item58f1a5d216:g:5HUAAOxyBotTadIe:rk:4:pf:1&LH_BIN=1&frcectupt=true

Well, this is interesting. MFG ran TWO 12g solid wires from the 15am fuse to the entertainment center. Certainly not what I was expecting.

I also may not have the physical space to do what I want to do without relocating a 120v outlet. Gonna have to think about this some more.

Well the wire will be thick enough so the original expected amperage will not melt the wire insulation. But the voltage drop will be excessive.

Litigation perhaps. If the fuse for the circuit was too big for the wire.

An inverter was never intended to be plugged into a distant 12v power port. A small inverter powering a light load might not have issues. But the ciggy plug and receptacle will increase their resistance with more use.

If the 12v ciggy receptacle is on the battery with 4 awg wire. The ciggy plug itself would still melt above 120 continuous watts.

LY,

That thing is SWEET.

I need to get into that area anyway, will look at the wire gauge. I'd be disturbed if they didn't properly size the wires for the wire, that would be a lawsuit just waiting to happen.

There is another recent thread with a poster having issues with a small inverter, which is distant from the batteries, trying to power a bedroom TV over the manufacturer provided wiring

If you want to install a distant ( from batteries) inverter, you are going to need thicker wiring than the manufacturer ran to the Tv area, especially if you plan to plug the inverter into a 12v power port/ciggy receptacle.

NO WAY, did the manufacturer run 10AWG, and even that gauge might not be enough to run a distant inverter powering both a TV and a Laptop with a depleted laptop battery.

And Ciggy plugs and receptacles, are a horrible eletrial connector. You do not want them powering inverters unless the wattage is never going to exceed 40 watts, if that.

The Ciggy plug and receptacle might be ubiquitous and convenient but they are horrible, and it is always best to bypass them in any critical task or when additional voltage drop is going to be a concern.

your linked product is quite expensive for what it is.

Here is a more functional similar unit for ~1/3 the price:

If you uplug in an inverter into a 12v ciggy receptacle/powerport using the wire guage the factory provided, the included voltmeter will make it obvious that he wire gauge the factory ran is completely inadequate for the load of TV and a alptopm, adn perhaps just the TV itself.

Some people get quite concerned when a person doesn't reply back within an hour or two. :B

there's a 12V line powering the radio and USB port next to the TV. TV that came with the TT is going to find some other purpose, being a TV in TT isn't one of them :) Anyway, it looks like the 12V line is wired to 15a fuse.

Thinking of mounting this product where the usb charging ports are, IF I do an inverter
