i used a Go Power 300w PSW in one RV

and a 300w MSW in a different RV

almost all electronics now use 'switching power supplies'

so you don't have to have PSW, inverter

I had a 400 watt PSW inverter.

I watch a lot of Antenna TV, on my 12vdc TV

Turn on the inverter, to power something else, and a few TV stations would instantly go away. Turn inverter off and they come right back. Not weak TV stations on the cusp or reception either. Seems the channels broadcast on actual VHF hi to about 19 were worst affected. This symptom is not voltage related, it is RFI related. My 12v TV works fine at 9.5v input, perhaps less.

So if pulling in distant TV stations on an antenna, perhaps even close ones, is what you want to use the TV for, then perhaps the inverter route is not the way to go.

I am biased, I am anti inverter when there are other options. I view them as a necessary evil, to be bypassed whenever possible. but that is my opinion.

I have a Go Power 300w PSW inverter. I really wanted a Morningstar Sure Sign 300 because it has no fan, but the cost difference was just too much for me.

But I've found that the fan doesn't come on in normal power usage so I can leave it on all night to charge phones and stuff in silence. Yes, direct 12v may save a quarter amp. I've got plenty of amps and like the simplicity of plugging things in like at home (as the electron manager of my family, I like to keep it simple).

My criteria was good reviews, cost, and heavy weight. Roughly in that order.

Both of my rigs came with CRT TVs, I replaced the Bounder TVs with LED sets, both sets came with wall warts and I just made up power cords myself. The Winnie ,however, has a 32" Class
Sharp up front and it does not have a wall wart so I run it off the factory installed 300 watt MSW inverter. Both of the BluRay players are twelve volt as does the bedroom 19" class set.

I have looked for a 12 volt adaptable LED set but cannot find one, it seems they are available in smaller sizes but not 32" class.

My rig did have a home entertainment system but the original owner took it out when he sold. I don't need surround sound in a RV but I want a sound bar to put the speakers in front and with better clarity. I can and will get a small sound bar with a wall wart.

I'll go with the inverter for now but eventually I'll find a 32" class set that has a wall wart and replace the Sharp.

Just for kicks I ran the bedroom set and BluRay player with a wall wart plugged in to a 75 watt inverter from HFT. My brother runs his printer and charges his computer in the field both from a small inverter with a cigar lighter plug. Neither one of us have had any problems with our cigar lighter inverters running electronics.

Use an inverter as you’ll need to charge your computer on occasion.

Super quiet.

Power inverter


I used to run my TV with a similar 150W inverter without a cooling fan, hence totally quiet. If you get an inverter much bigger than 120 to 150 watts it will have an annoying loud fan.

And if it's a real cheap one, it will run all the time.

I'm going to a add , that annoying depends on several factors
Like how sensitive your hearing is
And where the inverter is mounted
I don't sit next to the inverter, nor is it mounted close to the tv
In previous RVs ,The inverter was mounted near the batteries
And cord run to needed location

In this RV I mounted it in a storage bay and wired whole house

True for modern TVs. Not true for the old CRT style.

There are a few stations that broadcast on parts of the old VHF band, but most switched to UHF. Also, most "digital antennas", tune UHF better.

Remember with digital TV, the "channel number" has nothing to do with the actual frequency they are broadcasting on. The channel number is just there for human convenience/comfort !
