Review on 🔌 ANTAOCI 3-in-1 Multi USB Charging Cable with Retractable Design, One-Way Magnetic Connector, LED Light, and High-Speed 5A Data Transfer; Compatible with Cell Phones, Tablets, and More - Type C/Micro USB Charger Cable Included by Joshua Paulson

First off, I want to say right away that I'm not an electrical engineer, so I can't go into the details of why certain things happen, I can only explain what's happening. Second, my review unit is the Asus ROG 2, which is somewhat unique in that it has two USB-C ports for charging. It has a regular USB 2.0 port that supports Qualcomm QuickCharge 3.0, USB Power Delivery 3.0 and Asus fast charging. It then features a second side USB 3.1 Gen 2 port that supports Qualcomm QC 4.0/3.0, USB-PD 3.0 and Asus FC. This gives me a lot of flexibility in charging my phone and allows me to test a lot of things. Also Ah = amps per hour. For starters, this cable is USB 2.0 to USB-C, which immediately limits its fast charging capabilities as it cannot support more powerful USB PD charging modes, only regular USB fast charging. Also, regular USB chargers are simply not compatible with this cable. The maximum I've been able to push through with regular USB chargers with this cable is around 1.8Ah, but I can't always get that. Some USB chargers will not charge from a USB 3.1 port with this cable, but will work fine with a USB 2.0 port. My USB battery supports 3Ah, but with this cable for some reason it doesn't charge from the USB 3.1 port, and from the USB 2.0 port I have a maximum of about 1Ah. However, the other USB 2.0 USB-C cable I have works fine with my chargers or batteries and gets a solid 1.8Ah every time. The most consistent charging I've received with this cable is with Qualcomm QC chargers. Qualcomm develops its own specification with USB 2.0 cables in mind, so the performance is much better. With this cable and the QC 3.0 charger I was able to get over 2Ah+. If your phone/device supports Qualcomm QC, you won't have any problems. For my purposes, I got this because I needed a charging cable that would work with my USB battery and fold easily into my pocket. Ordinary USB cables cannot withstand the rigors of repeated twisting and untwisting in a tight pocket, so all of them are bound to fail, even the expensive, fancy, thickly braided cables. This product has solved the twisting problem as not only is it designed to twist, but its housing keeps the cable from putting too much strain when it's in my pocket. While for some reason the maximum capacity of the cable with my USB battery is around 1Ah, that's at least enough to noticeably charge my phone on the go so I can give it to him. The magnetic interchangeable tips are new but not a big deal to me although they are well designed and fit snugly into the cable. Oddly small at the moment, it was the best I could find after comparing all the options on Revain. I just wish my battery was at least 1.8Ah.
