For the Explorer 1000, why is the input wattage showing 120W when connected to two 100W panels at the same time?

In order to prevent the battery from overcharging, our power stations are regulated at a certain input voltage and current.

The SolarSaga 100W panel can reach up to 18V and the Explorer 1000 power station is limited to 6.33A.

Therefore, with 2 SolarSaga 100W panels combined, the maximum power input that's expected will be 18V x 6.33A which equals approximately 120W.
