Not sure what you mean by the 10:1 ratio. From what I've learned so far I've seen that different inverters draw different amount of amps depending on the wattage inverted.
12V in, 120v out !

TOO SMALL. At least 2000W

Thanks Piano, I didnt think about the leap the inverter would have to take from 12 as opposed to 48v. I would have liked to run a 12v system but I dont have but a month left before my lease is up. So maybe something for the future.
Can't change that down the road.

Laptop x2
Mp3player charger x2

Flashlight charger
Coleman lantern charger
Mini dehumidifier 22.50w
Small fan
Overhead lights
Coffee maker 700w (10mins daily)
4.5 cubic foot fridge (not 12v)
Printer (100-200v/.6a)
Heating pad
And a couple other odds and ends
With that I ended up with 2510wh / 202ah
That's without the coleman mach 3 AC on top.
If you leave the A/C out, a good quality 1500W continuous inverter and 200-225Ah of 12V batteries (two 6V golf cart batteries) would easily cover you for a couple of days.
