Can I charge other things with my Huawei p 30 pro?

Do you understand. I only understand. My cell phone can charge other things. Or. Oneself?

Can someone explain this to me, I'm very confused at the moment I tried to put my cell phone next to my other cell phone so the old one wanted to know whether I can charge it or steal electricity, does that work or have I misunderstood it?

"Reverse Wireless Charging" can be switched on in the settings and then you turn your mobile phone around and you can use it to charge other devices, for example, but only those that also support wireless charging!
