This is a funny thread. Lots of information that is practically worthless.
Here's the basic formula: volts x amps = watts
The math says that you can only get 8.3 amps out of it.
That's about right.

I have and use a Honda 1000 to charge two group 29 batteries.
The generator was chosen for three reasons:
It will run the converter, but of course, the converter is NOT going to supply 45 amps - so the converter will do it's best and the Honda 1000 will run at capacity using ECO mode.
Mostly, the converter can reach 14.1 volts when it tries to go into "boost" mode. I've only seen it reach 14.2 volts once in five years of use.
We don't drain our batteries down in general camping. Once or twice we've discharged them to around 12.4 or 12.5 volts. It takes a couple hours of generator run time in the morning and again in the after noon to get the batteries back up to the 12.7 or 12.8 float level.
(I've installed a volt meter by which I monitor battery condition:)
We usually have two or three laptop computers and cell phones charging during this time.
If you run your batteries down flat, then maybe you should get a Honda/Yamaha 2000.
Otherwise, a Honda 1000 will work for you just fine.

- Light weight
- It fits the storage space
- It will charge batteries
