We have the Jensen JRV215N stereo/camera/bluetooth/auxiliary speaker unit in our dash. It does so many things, I really don't know what to call it. However, related to this post, I am amazed at how much of the time it is on. And since it always has the time and date posted on it, when off, I'm guessing it is powered up 100% of the time. Ours is hooked to our TV and house speakers, so with either the TV on or the Sirius XM stereo providing music, it is on close to 100% of the time. I just wondered, yesterday, how long will this thing last if it is always on. So with all that babbling, I'm thinking that is why it is powered through the house batteries and therefore hooked up to the demand battery charger/converter.
