It's hard to use, and the wireless charge is 7.5w.
In fact, the iPhone mobile phone with wireless charger is not very good. I use a second generation se myself. Wireless charging is slow as hell. I think it's better to charge it fast. Or just use the original charger.
The iPhone11 also supports the 18W fast charge, which can be charged 28% in 15 minutes, 55% in 30 minutes, and 74% in 45 minutes. However, after opening the trickle charge protection mechanism, it takes 1 hour and 42 minutes to full 100%.
