He says a MSW inverter will destroy a laptop's battery. I never had that happen to mine.

He calls an AH an "amp" by saying 1 amp per hour is 24 amps per day.

and says "amps per hour", many times. It's likely a cheap MSW will overheat and possibly destroy the wart, not sure what happens to the battery.

BFL13,

In case you forgot--Mac computers may not do well with MSW. And electric sleeping blankets don't do well either. The price difference is simply not so great as it once was. I've replaced my 400 watt MSW with a Victron which I paid $79 usd for. My only complaint is it weighs 7 lbs.

A lot of 12 volt TVs are junk and cost more than a comparable 120 volt name brand version.


Which 12 volt TVs are junk? Can you give us some examples of failures and which components failed? I'm sure you've had some personal experiences with said failures. Please enlighten us.

I guess 'junk' is a bit harsh. I did purchase a Tyler brand TV from Amazon two years ago and the picture quality was so bad that I returned it. Some common brands for 12 volt TVs are Jensen, SuperSonic, and AXESS. Doing a search on Amazon I could not find one that was a smart TV. You are paying a premium price just for the 12 volt capability. My present TV in my RV is a 32" Vizio and I'm using a 300 watt GoPower PSW inverter. No load current is about 0.25 amps. Claimed efficiency is 80% to 90%.
