While trying to be succinct, I think I've left out information that would explain the questions.
1. Do I need an inverter to charge phone and computer from battery? ...in other words, if I install a 12v charging center, is it drawing directly from the battery, or does it need an inverter to convert power to AC. I ask this because my phone and computer normally plug into a AC power source in the house so does the charging center need an inverter to make it compatible with what the computer expects. I realize that plugging into the cigarette lighter, for instance gives USB items access to 12v power source. What I don't know (and if I did know I wouldn't need to ask this question) is whether there is an inverter behind the cigarette lighter.
2. Do I need an inverter to power 12 volt items? Again, not sure if these 12v items, like a fan which could plug into the cigarette lighter, are finding a power source with an inverter behind it.
If the answer to this question is that I don't need an inverter to run 12v, then it must also mean I don't need an inverter for question #1.
3. If my solar
charger is adequate, would my only need for a CONverter be to run 120V items?
Right, I do see this is backwards, which was unintentional. I should have asked, "would my only need for a converter be to charge the battery from shore power." Which is why you see the reference to the solar panel
, if it's adequate, maybe I don't need a converter either, at least not now.
