Is a small generator too small?

Would a tiny little generator like this be too small or any less efficient/slow at charging my trailers two 12v batteries? I know it can't run a lot but during the day not much really needs to be on if it's just humming away in the background. How much wattage can the trailer draw is the question I guess? I also have a 3100w Champion generator but am considering this just for lite stuff

Why a second generator? I have the 3100I and use it for everything. Use the econo mode when not running the A/C

Should have tons of power to charge the batteries. I used to charge mine with one smaller than that.

It will depend on the size of your battery charger, if the charger is over about 45 amps then this will be too small.

It's likely that your batteries could not accept all of the amperage that that generator could output without damage. Your charger would be set to limit that to an acceptable amperage, say battery capacity/8. For you that would probably be 50 DC amps (about 5 AC amps from your generator) Check battery manufacturer specs to be sure.
