Yes, a 150W power station can be compatible with a 60W mini-fridge. In fact, the power station's 150W output is more than enough to power the 60W mini-fridge.
When considering power compatibility, it's important to note that the power station's capacity (150W in this case) represents the maximum power it can supply. It doesn't mean it constantly outputs 150W; rather, it indicates its capability to handle loads up to that amount.
Since the mini-fridge requires 60W to operate, the power station can easily handle that load. You'll have a good amount of headroom in the power station's capacity, allowing you to plug in additional devices as well (as long as the total power draw doesn't exceed the power station's maximum capacity).
