Review on High-Speed Multi Retractable USB Charging Cable 4A, Minlu 4-in-1 USB Charger Cord for Dual Phone/Type C/Micro USB Ports Compatible with iPhone/Huawei/Samsung Galaxy/Pixel/Sony/LG/Tablets (3 Pack/4 Feet) by Tyler Dorsey

For some reason they don't support QC 3.0 charging at higher voltages. They can only be charged with 5V on my USB meter and around 1.8A (usually less than the maximum rating of 2.4A at 5V). This was tested on known QC-enabled cables, which worked great for fast charging. It's nice that they can charge multiple devices at the same time, but I didn't get close to a total charge of 4A. This may be due to the adapter as most adapters will not output more than 3A at 5V. Haven't decided yet whether to keep it or send it back. They seem pretty solid and not sure if there are any cables on the market that support fast charging, but their marketing claim on the website that it supports fast charging is why it gets a 2.
