I just received this specific product. The packaging is very good. Besides the charger, it also provides a type-C type-C cable that is not of good quality.
Unfortunately, things are not as described by the company.
I charge an S24 ultra in the first C1 port and the charger's indication reaches 31W while the phone manufacturer provides 45W. The truth is that on the phone, the charging description is super fast charge.
Now, if you simultaneously charge anything else in the C2 port, the indication for C1 drops from 31W to about 26W and of course, the phone describes it as fast charge, while logically the full charging time increases!!!
All of this with quality cables and not with the one provided for free.
In short, the more charges you put, the more the charging is delayed since the Watts are not constant as described and promised, but "drop" and are shared among the ports.
What a shame...
