Review on 🔌 iSeekerKit 3.0 Fast Charging Wall Charger with 4-Ports USB Adapter - Compatible with Galaxy S9 S8 Note 8 9, iPhone, iPad, Tablet, and 10W Wireless Charger by Jessica Washington

I made sure to specify a charging cable that can work with QC3.0 and 3.1A charging speed, my phone is designed for QC3.0 charging speed but this thing charges about the equivalent of 2A/5V (10W) from QC3.0 and about 1.5A/5V (7.5W) from 3.1A ports. I've tested this with other chargers I have and it's slow. It is speculated that QC3.0 can range from 3.7V to 20V to provide lower current and ultimately faster charging speed. This is not even close to the loading speed stated in the product description. I tested the 2.1A/5V charger and the 2.1A/5V charger charged faster than the QC3.0 and 3.1A ports.
