Those 4 panels in parallel would produce up to 21 amps. The maximum amperage that power station can accept is 10:
At best, the internal charge controller will limit the amperage successfully, and you will throw away half of your power. At worst, you fry your whole power station. You definitely don't want either, so don't run the panels in parallel.
Even running them as 2 strings of 2 would very slightly exceed the amperage limit. Most solar resources recommend a 25-30% current capacity overhead when selecting a charge controller to account for odd solar conditions, but you should probably be ok with that panel configuration.
If you run them all in series that could exceed the voltage limit of the power station when you get full sun. (4 x 18.7 V is about 75 V.) So your best bet is 2x2.
