Question about Bluetti AC200 Max

No, it is not possible to change the mains charging power to specific levels such as 300 W, 200 W or 100 W via the app. The maximum mains recharging power is 500 W per adapter, and the station can manage up to 1400 W in combined charging (mains + solar), but there is no mention in the available sources of setting the mains recharging power in stages via the app.
