The 1440W is the max input wattage for charging not the max output wattage. We ran the A/C all night & the unit lasted 8hrs through the night because the max draw for the A/C was when the compressor was running which cycled based on the temperature in the camper so it wasn't a constant high draw. We looked into upgrading the battery bank & inverter as you mention but that requires a bit of wiring changes to support the higher inverter from the factory 1000W inverter as well as connecting it up to run the A/C off the batteries so while it can be cheaper there are these aspects we took into account. The other aspect is that we can use the Anker to power other things not just the RV so that versatility also played a factor in our decision. Re: Jackery instead of generator Coleman Mach 8 roof top 13.5k unit. The softstart was needed to keep that initial amp hit low enough to be able to run the A/C with the Anker unit. Re: Jackery instead of generator We have an Anker F2000 solution (no expansion packs) that works well. We put in a softstart for our A/C & it can run that all night on a charge. To parrot what others have said though figure out what you want to run with it & your overall power needs. Having that will help determine what type of connection you will need (do you need a 15a, 30a or 50a output option), then determine how long you want to run the item(s) so you get something with enough output capacity to drive it (the A/C for us) & have a recharge plan or buy enough expansion packs to cover your needs & recharge plan. It is nice to be able to use the 120v outlets without having to run the inverter which is typically a big drain on the battery bank plus we get to run our A/C when others would have to shut their gas generators off for quiet hours. Lots of vehicles are coming with 120v outlets these days so you have the option to charge it up while driving around or using a solar recharge option. There are pros & cons for whichever "generator" route you go though so as with anything with camping/RVing, find what works/fits best for you & your needs & then just get out there & enjoy!
