That haier is expensive. I picked up a 22" 1080p RCA LED LCD for $150 on sale 2 months ago for the boat. Yes, I use a TV on an 18ft bowrider. Draws only 40 watts and the smallest inverter made runs it for hours, or at least til the game is over.


Yeah its expensive


Go to Newegg.com My wife bought a 22" Sony LED with free shipping for $159.00. (it was on sale, last July) It too is 1080P, BUT if your on the boat you don't need it unless you have Blu-ray, cable or any thing like that.

If you're feeling really frisky and good with electronics, you can take off the back cover of an LED LCD, remove the 120v power supply and replace it with a 12v computer power supply. They provide all the needed outputs (3.3v, 5v, 12v +/-) that a LED TV would need. No more need for an inverter and it's overhead.

I wouldn't attempt this with a standard LCD tv, they have cathode tubes providing the backlight that usually take 24v.

A TV that draws 40 watts will run on a standard 75 amp hour deep cycle for around 10 hours til the battery reaches 50% and it's time for a charge. If you're charging off the boat alternator... it won't fully recharge forever.

If you're smart and purchase an AGM deep cycle battery to run the inverter.. Like an Optima Blue Marine 75 amp hour deep cycle.. They are good to around 80% discharge and fully charge in 2-3 hours, not all day like a lead acid. They can be had for around $200. TV runtime @ 40 watts? 17 hours.

Really, what it comes down to is do the math. Add up all your watts used. How long do you watch TV for each day? What else do you use? Radio? Does it have an AMP or is it just a head unit? A standard agm deepcycle 75amp/hr battery can easily last all weekend with LED lighting and modern electronics.
