Power Consumption Refridgerators

Question

Hi there
I am in the process of buying a generator for power losses (I live in a rural area) to ensure the Fridge and Freezer are kept running. I want to assertain the power (wattage) of my Refridgerators so I can ensure I buy an appropriately sized generator. I have looked inside and out of each fridge and freezer and can find nothing on operating power consumption or startup power (which is important). We will likely only run one fridge/ freezer at a time during power outs. 1. 390L fridge freezer late 90s model, 2. 211L stand alone freezer early 90s model and 3. 220L (not certain) fridge stand alone (matches the 211L freezer). Can you help?
