12 volt inveter and TV or small portable DVD/TV?

That looks way longer than 12 inches. The camera must add a few inches.

I ran a 350 Watt inverter off my deep cycle while deer hunting in the shack this year.

My heater says it consumes 40Watts.

I'm not sure on the TV/DVD combo LCD TV closest specs say ~80Watts.

I had my propane/CO detector plugged in also.

I watched 3 movies and the furnace ran 2 entire nights.

It all ran fine.

All inverters are not created equal. Look for the highest efficiency rating so you are not wasting power.

I had 2 batteries banked and all 12v lights, fans and 300w inverter going into the same battery connection and was only getting a few hours when running a 32" LED dvd/combo. When I would turn range hood fan on the inverter alarm would go on. Today I got another battery and hooked up just the inverter and it ran the TV with dvd for over 10 hours. Seems my other batteries were the problem. I am pleased that it was the batteries, I want to run tv without using the generator and found I can with out to my drain on the battery.

Voltage drop is the key. I only run one battery for led lights and Tv. I run a cheapo 400watt inverter on a 19"lcd tv with a dvd player or Dish. I originaly had the inverter pluged into a cigerette lighter plug and I could get about 6-8hrs out of it before the inverter "low voltage shutdown" would kick in. Now I have the inverter 18" from the battery with 6ga cables, now I can get atleast 12-14 hrs.

Just put on a 100w solar panel to charge the battery, I hoping to never have to charge the battery again.

As for the advice that the player or any TV for that matter could be run directly off 12 volts....it's good advice to check that out. It's a possibility that you could skip the inverter, but not likely. There are very few things that actually run on 12 volts that weren't designed specifically for automotive use. It's a good idea to check, just saying don't get your hopes up that it's a 12 volt appliance. I just double checked, and my laptop runs on 19 volts, my son's DVD player runs on 9.5 volts, and of course the transformers that charge all the tablets around here put out 5 volts. But obviously check it out just in case.

You're probably correct on normal TV's because they are designed to run on 120 i assume, normal plug and all, but I think you might be mistaken for the portable DVD player. I know on my daughters DVD player, if she plugs it into the wall, there is a big inline transformer. If she uses the cig plug in the truck, it's a straight line. These are "portable" so it makes sense. Think of all the phone chargers, they are using transformers on the block you plug into the wall. They may not be running 12v, could be 9 or 19, but if you're using the factory plug that came with the item or a suitable replacement, I dont see the reason to convert from 12, up to 120 and then back down to 9, when you could just go direct from 12 to 9.

I'm just saying that everything that has a transformer and runs on DC doesn't necessarily run on 12 volts. Ron Vroom (the person I was responding to originally) said that it'll hook up directly to the battery if it runs on 12 volts, and he was correct. I was simply saying that the odds aren't good that you're going to find your things wanting 12 volts exactly. They're often going to require SOME kind of power conversion (DC to DC at a minimum). My examples were fairly clear, I read the voltages off the transformers for those devices. The laptop runs on 19 volts, it won't hook up to a 12 volt battery and run. The DVD player my son has with the 9 inch screen has a wall transformer that outputs 9.5 volts. I don't know what it'll do if you hook it to 12. It might work, or it might wreck the thing. I'd guess that you'd have to get a DC charger specifically for it to downconvert the 12 volts to 9.5 to be safe, but who knows. The DC charger for your phone converts from 12 volts to 5 volts, and it's very likely that the DC charger for your daughter's player converts from 12 to 9 in much the same way. It's also possible that it just shoots 12 volts into the thing and it is happy with the 12, who knows until you measure it

Soon, what started as a "just hook it to the 12 volt battery with the right size plug" ends in a up being an adventure because the appliances aren't always going to work on 12 volts. In the end I question whether you're much better off with the 12 volt plugs that either plug in 12 volts directly or downconvert to the correct voltage, or just buying the $25 inverter that will allow you to run a myriad of things such things as the original TV/DVD player as well as AA/AAA eneloop battery charger for your headlamps, the aquarium bubbler for the bait, the laptop charging cord, the digital camera batter charger, and any number of other "AC" appliances, at the cost of being maybe 10% less power efficient.

I am up on URL and I watched tv and also watched 4 DVD and had no issues at all. My inverot plugs into a cigar attar lighter socket I have by the cabinets up by the tv. TV has a DVD player in it, worked great the last 1.5 days and the batteries will get a recharge tomorrow am when I fire up the generator to make coffee.
