Question for anyone with this or a similar capacity unit: what is the main use case for it? I have a Delta 2 (1800W, 1kWh) and that can (and has) been used to keep my refrigerator up and running during outages - which has been extremely helpful and already paid for itself in avoiding spoiled food.

I have also used it once or twice for outdoor parties to power a crock pot or whatever.

Obviously this is smaller and lighter and would be easier for the outdoor party scenario - but needing a power station for that is a pretty rare occurrence for me. I assume this would not be powerful enough to run a full-size refrigerator (yes while running they draw 150-250W, but the startup surge is much more than that - and even if it could handle the surge, the runtime would be low). So what do people use units like this (not necessarily this exact model) for? Or does having a Delta 2 mean I don't really need this?

We use our smaller one like this mostly for charging devices (sometimes even an electric tea kettle) when camping, kids sporting events, or at the beach. I dont have this specific one but the one I have is small enough and more easily portable than the Delta 2, making it easy to grab and go.

Larger ones like 1500W+ have a lot more application like powering refrigerator(s) during power failures. The smaller ones are convenient for powering smaller appliances that need power (during outages or too far from an outlet) like your phones, tablets, router &/or fiber to cable converter, plug in appliances like fans, lights, humidifier, dehumidifier, sump &/or well water pumps, recharging batteries at a worksite, shed, camping, ice fishing, boating, etc.

I use the smaller one to power my refrigerator when recharging my larger one with solar panels or generator.

With a large power backup device and a couple smaller ones and a generator, you can use the batteries until they are depleted, then recharge them with the generator until the batteries are recharged. Then turn off the generator until the batteries get low.

If my math is correct, this would power a 60w cooler refrigerator for 7 hours at least?

Around there or a little lessCount that as run time - cooler turns on then turns off. If the stuff inside is cold it runs less - if the stuff inside has to be cooled down it has to be cooled down it will run longerIf you keep it closed it will run less etc

Even when it's not running the inverter being on will use some power
