How many Ah
I need a battery bank to power a mini fridge 1.3 amps @ 120v for 48 hours and a electric blanket 200 watts @120v 8 hours as well as computer and cell phone charging, how many Ah will I need?

... so I'd say a minimum of 500 Ah if you aren't talking about lithium batteries. Six GC2 golf cart batteries would be one reasonable setup (with a bit of margin).
I concur ! (Very reasonable "back of the envelope calculation" with cushion !) Skip the electric blanket and you can by with 4 (electric heating pads work better).

Ok so the batteries will be Lifeline AGMs probably the GPL-31XT, I was thinking of starting with two.
That is about 250 Ah. 24 hours, probably less.
Six flooded (non-AGM) golf cart batteries will give you 600-650 Ah and will save you over $300 and give your 48 hours. Four AGM golf cart batteries will be in the same price range as your two GPL-31XT but will give you 400-450 Ah.
