I have a 22" LED TV that needs 14 Volts 35 Watts. Will this run it off my 12 Volt battery? The 120V AC power supply it came with outputs 14V 2.5 Amps.

It should do just fine, I would make sure the voltage was adjusted properly under a load be for powering the TV
1035814
By my figuring 150 watts@14volts equals a little more than 10 amps so the answer is YES it should work, but be sure to mount the power supply so that the heat sinks have plenty of air circulation. Not a closed box!
1035815
If I remember my math correctly you need 35 watts max, so it should be able to handle your situation with sufficient reserve.

The problem is this power supply output needs to be at least two volts higher than the input. If are charging the battery your voltage is 14.4 volts. This TV should work direct connected.
1035817
I'd bet that your 22" (LED back lit) TV would work properly directly off of your 12 volt battery. A 12v battery is 13.8 volts when 100% charged and 12 volts when at 25% charge. This module needs to boost the voltage by a minimum of 2V so it would not work with a 14V output from a 12V battery. It would work off of a 6V battery.

It should work but as the battery voltage drops the output will have to be adjusted as it will not regulate the same. When the volts on input drop the output drops. A digital one may help with that.

I'm going to assume it's a standard 120v television, so you will have to power an inverter to get the 12v DC up to 120v AC. You have some loss in that process.The basic math is battery voltage x battery Ah so 12x35=420 wh. watt hours. That will run 420 watts for 1 hour, 210 watts for 2 hours etc. In theory. But you never want to drain your batteries below a certain point. I've been warned not to discharge batteries more than 50%. Plus the loss from the inverter, lines etc. You would be looking at 6 batteries just for this simple math not even taking into account the discharge factor. If I'm wrong on any of this someone please point it out. I'm going to assume it's a standard 120v television, so you will have to power an inverter to get the 12v DC up to 120v AC.

It will run on as little as 14watts at 12v. Anything less and it flips off and on.

Carefully check the label near the power plug on your TV again. The information may be moulded into the plastic on the back of the set. You might need a magnifying glass and a flashlight to read it. Very few electronic appliances made today will only work on 120/60 power. They almost all use switching power supplies, which will run on 120-240V 50-60 Hz.

Confirm the power rating of the TV from the sticker on the back usually 40-50watts , I used a 90 watt laprop charger all the time so it should work fine for you also

Hi, the output is limited to whatever the input power is. Example: 12 volts @ 20 amps is 240watts total available power. If you convert it to 24 volts, you only have 10 amp outpue minus whatever the conversion draws. You can't get power out of things air. Make sure to use additional heatsinks as these are rated 150 watts max. Good luck!!

My guess would be YES, ABSOLUTELY. I run a 28" LED TV for 8 hours on a single charge. I'm not a scientist, but you can calculate how many watts of power are used: go here to this website -- https://www.batteryweb.com/pdf/inverter_battery_sizing_faq.pdf

Yes, a 15 amp circuit / outlet will be enough to run it the power supply with the load you indicated. Here's the theory: 200 watts / 83% efficiency = 241 watts input power, or 2 amps at 120VAC The 15 amp circuit will have 13 amps left over for other uses.See the manufacturer's datasheet, model NES-350-12 for more technical details: http://www.meanwell.com/search/NES-350/NES-350-spec.pdf

I am using mine to run a 24 watts LED strip. The power supply is rating 60 watts, but is not a good idea to run any power supply to the maximum capacity.

The unit is a 110 plug but I would make sure your not plugging it into the same outlet as your TV .I think it says 115 volt plug in ..it is the same as 110 volt standard

I run it on a 15 amp circuit and haven't had any problems with it. I hope this helps.

Hello Icepuck72!The unit will run your bar, because, as I looked around, I saw that this vintage type will draw between 25 to 35 amps. The Powermax at 55 amps should do the job. Just make sure to respect the colour code when placing the wires into their respect + and - or positive and negative outputs. Yes, this unit does also charge batteries but is primarily a power supply at 12 volts 55 amps. As the other person mentioned, normally, Camper trailers and RV's use this unit. Best of luck, and I'm sure your son will love it. Live well and have a great and healthy summer. Antonio

Yes DVD and TV run off of my 12vt plug in. I have a travel trailer an the 24" combo. They seem to work fine. I have to use the remote to operate the DVD. Hope this helps

This is a 30 Watt supply. It is fine for one 16 foot 3528 LED strip (typically consumes about 16W) I have also found that it is OK for one 16 foot 5500 LED strip (typically consumes about 22 Watt). This supply will not run even one 16 foot, high-power LED strip. (I have found that 5630 LED strip (16 foot) can consume as much as 42 Watts - The 5630 LED strip definitely overloads this supply)

Watts=volts*amps... so 300 watts / 12 volts is 25 amps minimum for max power output. As to the tv/dvd player - hope you mean LCD, should be no problem, crt could be.

Yes. If your LED is 30W and runs on 24-30V then it draws 1.33-1.0 amps respectively. The converter can output 3A continuously and the requirement on voltage is that the maximum ratio of output voltage to input voltage is 3. So since you're putting 12V in, you can get 24 or 30V out easily, and this still keeps you under the current limit. Hope this helps, the converter has been good for me, it's very stable on the output despite a changing input. If I can be anymore help let me know. -Brian

The only right answer to your question is, "it depends", because it depends on how much current you need to provide and for how long @ 120V AC. Since you are running a 12VDC input and a 120VAC ouput, you need about 10 times the current on the 12v side as you want out of the 120V side. Additionally, you need to have an understanding of Amp Hours capacity of the battery(s) used to provide the power to understand how long it(they) can provide the power needed.
