Running TV off battery in Bambi Sport 16

I was wondering if I could run the Samsung Television that came with my 2015 Bambi Sport off of just the battery? It looks like the TV Is 12v but presently only runs on shore power or through an inverter. I thought I read on a thread somewhere that if I purchased or made a cigarette lighter adapter plug I could run the TV off the battery. The 2015 Sport 16 doesn't come with a 12v plug, but I switched one of the USB plugs for one. I also read that a 12v regulator would help keep the RV from wigging out from voltage fluctuations. Any thoughts on how to run the existing TV off battery?

IF the TV has a separate power supply and sends 12V DC to the TV, then all you need to do is make a cable to run from the cigarette lighter socket to the TV. If you still have a Radio Shack in your area, take the TV power supply to them and have them get you the parts you need, particularly the plug for the TV. Unless the power supply sends 12V AC to the TV you will need to observe polarity. Either the TV or the power supply or both should have a diagram showing which part of the TV connector is positive and should be connetcted to the tip of the cigarette lighter plug. In most cases, the center of the TV plug is positive, but not all, so you must be careful or you could kill the TV.

TV on 12V

Our 2011 16ft has a 120V tv set. We have used a small inverter to power it. Can't do it for a long time, esp with heater on, unless have solar to recharge next day. So, TV set draws little enough to run with small inverter, but the larger question is your overall 12V drain and charge. Try never to take battery down more than 50%, otherwise its life is reduced a lot.

What I did is replace the t.v. Antenna amplifier wall plate with a upgrade wall plate that has a 12 volt power outlet , then I bought a small 75 watt power inverter that plugs directly into the TV wall plate amplifier 12 volt plug and voila! Just plug the TV 120 volt cord into the inverter ,took a whole 5 minutes to upgrade the TV amplifier wall plug! I got it from Amazon it's a original wine guard wall plug - amplifier outlet. No modifications ,mounts in original location no drilling .

Many smaller TV sets are actually 12V DC already... they simply have a pwr supply built into the cord to convert the 110 VAC to 12V DC for the television's use. Check yours closely. If it uses a corded pwr supply (such as many laptop computers) you may find that to be the case. In such cases, a simple cigar-lighter type plug is probably all that is needed. (In fact, if you have purchased an after-market TV then the packaging probably included such a cord.)
The data-box on the rear of your TV should indicate the voltage and current requirements.
