Running my mini fridge of a power inverter

[Trinibob]

My new trailer has a mini fridge in the outside kitchen that runs off of 110 power only.
I'm going to Install a 12 volt outlet plug in that area to run a power inverter so that I may plug the refrigerator into it. With my battery setup I will have ample power for this system I'm just wondering the size inverter I need to purchase. Of course my manual has 0 information regarding the amperage and what age of the fridge all the online literature states that most mini fridges run off 90 watts. This set up by far will be cheaper than ice when we are dry camping thanks I have time for the help.

90 watts is 90 watts. When connected to 120VAC the refrig would draw 90/120 or .75 amps.

If using and inverter (assuming 100% efficiency) 90/12volts is 7.5 amps.

No inverter is 100% efficient so I would use about 125watt inverter to make sure you are covered.

Thanks that's what I thought I am currently running a 300 watt inverter.
