I did the same test with my delta 2. I tested a 6BTU windows ac unit and it only lasted about 50 minutes. The unit was pulling about 550 watts when compressor kick in. My out conclusion is, this delta 2 is good but for small appliances, or for campion, in a real emergency post hurricane etc this will not save you
I'd try a 6000 BTU window unit (no larger), and put it on Eco-mode. You might get better results. And, yes, definitely use an expansion battery. You'll need to close the room off and maybe put some towels under the door. Good start. Using these on an AC is definitely a learning experience.
If you're doing a test why not run it at the max capacity to actually see what it can handle and also what your AC is putting out if you were to put it on 10
That would have been a good idea. The settings I used are what I normally use. The reality is, even when plugged into your house, a window AC unit uses an incredibly high amount of electricity. The takeaway from my video should be, using a battery to run an AC is not a long term option.
