I am planning to buy an 2400W inverter generator to replace my 3000W non-inverter generator. HOPING the 2400W will run my AC (3000W works fine). Cost about $1,500.00 Question: Could I buy a 20 AMP 12 volt power supply ($100),,, plug it into my 3000W,, then plug in my 400W portable inverter ($50) to the power supply and charge my boat batteries with it? I guess the missing data is, what is the draw on my charger??? Looking that up now. Anyone tried this???

be careful down sizing to much to run a/c that start up for the a/c is when it pulls it biggest load to get the compressor going if you are to close to max amps you will trip breakers, my brother in law found that out this year (especially when the a/c has been on and has built up head pressure) it takes some amps to get the compressor going again under load :dontknow:
I"m confused a little. Why wouldn't you just plug your boat into your camper outlet once it is under generator power. For my 5th wheel I have an on board 4000 watt generator that I rarely use. I have a suitcase 2000 watt that I take with me. On trips like last weekend, I run the small generator to charge everything. I plug the camper to the generator, and boat to the camper. If I need the extra power to run the a/c, I use the big generator.
I'm trying to lighten my load,, I want just one generator. The 3000 I have may damage the charger and other smaller items. Problem solved,,, I received an email from Promarnier. They told me that I can run my Promariner8 (2 battery system) easily with my 400 Watt inverter. Therefore I have two options (IN AN EMERGENCY). Since I have a starting battery SEPERATE from my trolling batteries I can charge the trollers on-board as I move about the lake. I will have to watch the voltage on my locator's to be sure NOT to run it down to far. Option two,,, plug inverter into the car and plug charger (cord from car to boat) into it. Then I could charge the system "on the road". I HATE hooking up the boat only to find I forgot (I'm getting old) to charge the batteries. Hopefully this will help people too.

If I'm reading your post correctly, this company also has what your looking for? Product options to charge your batteries with your outboard motor and while trailering your boat to/from the lake. http://www.stayncharge.com
