Continuous AC Power From 110

So I have the Ac200L and I’m looking to continually power my small travel trailer. I bought the travel trailer to live in while I completly restore my house. The house doesn’t have power but I have a garage that’s about 75 yards away that I have an extension cord I’m looking to charge the power station with. I’m looking for a way to continually charge my trailer 24 hours a day using the Bluetti via pass though. Any help would be appreciated
