My meanwell adjustable voltage power supply will be in operation 2 years in October. I tend to use it at full output at least once a week, and overnight floating at 13.6v a night or 2 a week, more in winter.
It is power factor corrected meaning it puts out more dc amp output for less AC input than a non PFC power supply/charger/converter.
I have never tried powering it on a Honda 1000, nor have I measured its AC amperage at full DC output but I am pretty sure it can be powered by a honda 1000 at full output not on eco mode and not at too high an elevation.
It is a 500 watt power supply which can hold 600 watts.

Adjusting the voltage with the tiny potentiometer on the unit is not so easy, and the mini potentiometer is only rated for about 50 cycles/ adjustments.
I replaced it with a 10 turn 1k OHM potentiometer but this voided the warranty as I opened it up to access the circuit board.
If it failed tomorrow, I'd still buy another one over any other option.
My extra heatsinking and ventilation should greatly extend its longevity. Without the extra fans the privided 40MM fan would kick on often and it was very loud even at low amperage output levels. With the extra heatsinking and ventilation the loud fan only turns after 10 + minutes at 34+ amps and 65f+ ambient temps.
If you got some DIY in you the meanwell makes a very good option. Without the DIY confidence, the adjustable voltage powermax appeared( past tense) to be the best OTC adjustable option.
If you got a honda 2000 then the Meanwell rsp-750-15 is likely the better choice. Set it to 15 volts and run it as long as you care to run the generator and it should hold 60 amps solid until the batteries cannot accept 60 amps.
There is the option of a Megawatt power supply. Less expensive but similar in function, but the max voltage will only be 15.3 to 15.5v and Trojan has recently upped their recommended EQ voltages from 15.5 to 16.2v.
My previous flooded battery ( group31 USbattery) needed 16V eq charges, 15.5v would just bubble vigorously without raising Specific gravity to the maximum. 16V could do the task in under 2 hours.

JimInDenver had a megawatt but it failed, and I think the suspected culprit was fan failure/overheating, but the autopsy has not yet been performed.
I had a PD9245 briefly when i designed up a friend's portable(100+#) powerpack. It was nice to press a button and force the charger to seek 14.4v, but it would only exceed 40 amps for the first few minutes before settling in the 38 amp range. My meanwell could charge faster if it were a race, and Generator recharging can be considered a race.
PDs have a better longevity reputation than does powermax.
Iotas can be opened up, and warranty voided, but can be adjusted via a potentiometer to a higher absorption voltage and are said to be able to hold their max rated output when on a generator better than the PD's.
I have run my 25 amp schumacher and my 40 amp Meanwell in parallel without issue, other than having to bump the meanwell voltage to over 15 to keep it at full output until the battery could not accept more than 65 amps. Once it could only accept 40 amps or less I'd just remove the schumacher and set voltage to the desired voltage based on temperature and manufacturer recommendations.
I know some fear parallel charging sources, but issues really only arise when the battery has reached the absorption voltage of one charger or the other, and at that point usually one of the chargers can take over to hold that absorption voltage. When there is the word 'automatic' involved in a charging source, then they get confused when the other charging source has battery voltage above 12.6 or so, so one needs to trick the smart charger into going into bulk mode, by lowering voltage below this threshold by applying a large load on battery then restarting both chargers at nearly the same time, then removing load from battery.
Having 2 plug in charging sources gives you some safety net too.
If your batteries are sulfated, then they will rise to absorption voltage faster and amps start tapering earlier. The EQ charge performed every so often can allow the batteries to take more amperage and rise to absorption voltage slower, basically recharging faster to the 80% charged level.
If 40 amps nearly instantly brings your current batteries to absorption voltage, then there is no benefit to having a 60 amp charger, other than it will not get as hot, and when you do replace the batteries, then the new ones should be easily able to accept 60 amps and voltage rise slower to absorption voltage.
in general, with generator recharging, blast them with as high an amperage as you can muster, and have a charging source which seeks and holds 14.4+ volts the entire time the generator is running.
The PD's charge wizard/pendant can force it to seek 14.4v or 14.8v if that specific model (14.8v) is chosen.
A life at maximum output is hard on any charging source, so another computer fan resting against the case can allow it to not only last longer, but output more amps for longer while the generator runs feeding heavily depleted batteries which can still accept more than the charging source(s) can generate
