Buy the Honda Generator. Reliable and does the job. I have not owned a "Goal Zero power station"--but have cru9sed with a boat which had one. He was very disappointed by its performance. It would not run his portable chest freezer reliably at Lake Powell--probably one of the best places to use solar energy in the US.
For a refrigerator, depending on size, 200 watts of 12-volt solar power necessary for running a chest type or medium Norcold 12 refrigerator with a Danfoss compressor. My personal experience is with a 200-watt solar panel on a 42 foot RV, with a 22 cu foot Refrigerator. run through an inverter system. I have also run both 12 volts refers, on up to 110 V AC 12 cu foot Refers thru an inverter also. I have liFePO4 batteries--which have a usable capacity of 200 amp hours on my boat, and run two chests refer/freezers: 55 liters and 45 liters. The current draw of each of these is in the neighborhood of 60 amp-hours per 24 hour period. How much power does a 100 watt or 200-watt solar power generate during daylight?
The "
Power Station" is nothing more than a battery and inverter. You can put together a "station" which is better for a bit less.
If you just want to charge batteries--there are far better ways, involving solar panels, an MPPT controller. Probably best to go with a bigger battery bank, if you want 24-hour refrigeration.
