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?

If you mean energy from a 12 volt battery, conversions from 120 v to 12 volts will mean ten times as much current.
It will require at least ten times as much current from a 12 volt battery to convert to 120 volts
fridge 1.3 amps @ 120v for 48 hours AH = 1.3 x 10 x 48 = 624
electric blanket 200 watts @120v 8 hours
200 watts at 12 volts is 200/12 = 16.67 Amps. AH = 16.67x 8 = 133 AH
