I’m considering purchasing the charger 2 to charge my AC240 faster than what it does now. I believe the AC240 is limited to being charged at 10amps but I can increase the charge voltage upwards to 48vdc. ( correct me if I’m wrong). So if I charge it at 48v times 10 amps would be 480W. But it does not say if the output voltage of the charger can be adjusted up to a higher output voltage to achieve higher wattage. This being said the charger 1 will probably be enough it has a combined output of 560watts. And its output voltage can be adjusted up to 48/56 volts. Am I correct on this?. Bluetti I find is lacking some critical information

I don’t own an AC240, however, the user manual states 60V at 21A (not 10A) for up to 1,200W. (Check your user manual)
Charger 1, I do own, it will charge 56V at 10A for up to 560W, also stated in its manual.
Charger 2, I do not own, its stated output is also 56V and at 24A for up to 1,200W dual input of 800W from alternator and up to 600W from solar. Also stated in its manual.
This is all of the critical info needed and the user manuals for all products are freely avaialble online at the Bluetti store.
Charger 1 set to max output will safely charge your AC240 at 560W.
Charger 2 set to max alternator output will safely charge the AC240 at up to 800W and if solar is added up to 1,200W also safely. All parameters are within the AC240 input range.
Your primary concern would be; Will your alternator have enough spare capacity to run these loads? This is on you to decide relative to your specific vehicle and other loads that may have been added. You may need to consult an auto electrician to determine this factor.
i.e. I have a caravan DC-DC load, plus an Auxilliary battery, in the 4x4, DC-DC charger and anti sway added. I do not have enough spare alternator output to run the Charger 1 at full power. So, it is set to around 300W output which is better than a cig socket output and much better than nothing,
