Mordicai81 has a good suggestion. Keep in mind that oem converter is only as good as needed to get you to buy and make it through the warranty year. And, if you are usually using hookups it will be fine. If you are off grid, you need the charge time to be useful. A good 60 amp charger should run on your 2000i Honda. Bring the "good" charger and gen when you need, and use the built in converter when you have hookups.
But, be careful shopping for a charger, they advertise peek amps that are unrealistic. Some say 80 amps and are really only 20.
