Will a 1000 watt generator charge a battery?

An 800 – 1000 watt generator will charge the batts nicely BUT you have to be sure to not be drawing too much 12v current at the same time. Otherwise, the gen output just powers your load (through the TT converter), leaving little power to go into the batteries.

Can you power a travel trailer with a generator?

Generators work like RV shore power as they plug into your AC system and provide AC power. A 1000-watt generator is about right for a small RV or if you don’t need to run major systems like air conditioning. A 3500-watt generator is usually the next step up and can run most RV systems on most RVs.
