Those ratings are 1.5 and 1.3 amps at 115vac input, which is a different kettle of fish when comparing to DC fridges at 12-13vdc.I think a lot depends on the fridge, size etc...
Looking at the cheap Insignia 3.5 cu /ft mini fridge, it is rated at 1.5 amps... https://www.bestbuy.com/site/insignia-3-3-cu-ft-mini-fridge-black/6195311.p?skuId=6195311
The RCA 3.2 cu/ft is rated at 1.3 amps. https://www.amazon.com/RCA-RFR321-FR320-Refrigerator-Fridge-Stainless/dp/B00IR8H55A/ref=sr_1_6?keywords=mini+fridge&qid=1580322184&sr=8-6
One problem for shopping for a mini fridge many MFGs don't list power consumption in the promotional material.
The only acceptable comparison for power between a DC fridge and an AC fridge on an inverter would be to compare the DC current draw at the inverter input.
