Hi everybody, been a lurker for some time now, new poster. I like to think I have a decent amount of electrical knowledge until I see some of the threads on here! Lol.
Here's my fiasco:
I am building (another) "Cooler Stereo" which is just what it sounds like. A 12v stereo system built into a cooler. I've built a few before and am on a monstrous one now, 150qt Cooler on a heavy duty off road wagon axle kit.
It houses a bunch of electronics, as well as having about 70 useable quarts of space still. I have a large deep cycle 12v battery, I believe it's around 125AH. I also have an on-board charger, which charges at up to 10a. (Genius brand)
I went a huge step further with this build and incorporated a 19" LED TV in the underside of the lid in this one. It's an "Element" brand, very common set used in RV's, Boats and cars because of the ability to run on 12v. I have read thread after thread of people just snipping the cord at the power brick (120v AC input to brick, brick outputs 12v DC) and splicing it to a cigarette lighter plug or hardwiring it.
I hard wired mine with a fuse and switch, but my question is, how sensitive is it to voltage spikes? It works phenomenally at the resting 12.6ish volts my battery sits at.
I watched an hour long episode of a Netflix show, playing through the headunit in the cooler, and had very little battery drain. I was impressed, but I digress.
When I charge the cooler, the charger sometimes reaches 14v (14.4ish seems to be the highest I have saw, but then again, I haven't really ever drained it much. Just been "top offs"). I have always kept the TV off (the switch cuts power to the TV, I'm not talking just having the TV off).
My question is, would that 14v hurt the TV? Does it have some kind of voltage step down unit inside or anything? I don't want to risk it and "just try it" like some other forums have said. (I've seen a few threads similar to what I'm asking, but never once a definite answer) I picked up the last unit Meijer had, and they weren't getting any more of these in stock. (The new model did-away with 12v, and has a straight AC cord permanently attached. Don't ask me how I know lol)
Thanks guys for any input! Appreciated in advance!
