Two days of use only, but the first impressions are excellent. It charges the iPhone X, watch, and AirPods Pro without any problem. It works without needing to plug it into a socket, but directly into a port.
If there is a problem, I will write again.
Update 16/02/2023. It doesn't always charge the watch. While it starts sometimes, it turns off after a while, and a couple of times it raised the temperature of the watch to a crazy level, causing it to turn off. To turn it back on, I had to wait for the temperature to drop, otherwise it wouldn't turn on. The first time I thought it was a coincidence, so I tried again, but when it happened again, I charged it with the watch's charger.
I never had any issues with the phone and AirPods.
I wouldn't recommend it and wouldn't buy it again since it doesn't do what it claims.
