Default Crazy Trickle Charging Question

Is this a terrible idea or genius?

I have this charger on my boat:

My boat also has an outlet for cig style chargers to get plugged into. If I got a converter, like this...

Could I plug in my trickle charger to the boat while the engine is trolling or cruising?

To understand

While underway you want to use the DC to AC converter to charge an AC trickle charger to put DC power to your batteries? This in fact has nothing to do with your smart charger?

FYI The 140 watts from that walmart converter is no where near enough power for that smart charger. You may actually damage the smart charger. If you have a trickle charger, it may work, but I cannot see this being worth while. If you are charging a house battery while trickle charging it, you are going to charge a strain on that trickle charger and cheap converter. A small burn out or fire comes to mind.

What batteries are you trying to charge with the trickle charger?

I looked it up. At best those things put out 200 watts and my smart charger needs 800+.

If you were using your smart charger, then that would be bad. Aside that your engine recharges your battery. If you need to charge other batteries while underway, look for a VSR. I do not offer them but there are tons of resources here.

A VSR lets you connect batteries together for charging from the engine's alternator. It is an automatic switch between them. I do not sell them, but there are many here on THT with knowledge on them.

Why would you even want to use charger if the engine puts out up to 45 Amps?

I think the Yamaha may even have 2 separate battery charging outputs too.

No, the power inverter can not supply enough power, only 140 watts, you need more than 600 watts for the battery charger.

And the 12 DC volts on the cig lighter comes from the battery, the battery can't supply the power to charge itself !!
