Review on USB C Female to Female Adapter (2 Pack) PD 100W Quick Charge Type C Coupler Extender Extension Connector for Thunderbolt 3 MacBook, Nintendo Switch, Samsung - Cellularize by Kelvin Hernandez

For a simple device this kind of works if you hold it right (which can be a little annoying when trying to charge something like a power bank in a bag like I was where You weren't able to see clearly if it's charging or not.) However, for more complex devices, the disposable nature of this adapter interrupts the adjustment process, resulting in the case of my power bank for my Chromebook, either no charging or reverse charging. My phone using this has half the charging speed compared to not using it (probably a bigger issue for devices that only support 5V like my OnePlus 8 as this thing is said to have half as many conductors as it should, which causes double the voltage drop.) Just buy an extension cord.
