I need a 15 amp portable charger that I can run from my 450 watt inverter gennie. Battery bank will be right around 100 ah, AGM batteries. Here are some possibilities I found on Amazon:

I'd love to go with a larger charger but I'm constrained by the 450 watt streaming capacity of my little gennie (Powerhouse). Ideas? Thanks!

I think your approach is a little bit backwards thinking. Most of the experienced folks here don't top off the battery in the evening, that's a job for a solar panel system. A generator and charging batteries is best done first thing in the morning, when the batteries are low in charge, where a generator and battery charger do the most benefit to the battery, in the least amount of time on the least amount of fuel.

Most prefer to top off charge a battery with a solar panel.

You've placed some severe limits on your ability to recharge efficiently by buying such a low capacity generator with only 3.75 amps at 120v output. A 1000 watt generator would have been better, as well as an inexpensive 30 amp 12v power supply, like the Mega Watt or Mean Well units.
