Can you charge Mavic Air 2 using powerbank? Found this online and I'm confused

[Yaros]

I have been flying my Mavic Air 2 for about 7 months now, and I'm satisfied. One feature I'm missing is the ability to charge using USB. As far as I know that's not possible, but this website says otherwise. It says that you can charge a battery using the powerbank adapter that's included with the fly more combo. But that adapter is only for charging other devices with the MA2 battery, not the other way around, right? Check this screenshot of the website, I highlighted the confusing part:



So... am I right or the website is right?
