Review on MOSWAG USB C OTG Adapter USB Type C Splitter with USB C Female and USB A Female – Compatible with ⚡️ Chromecast, Google TV, Samsung S21 S20 S20+, Ultra, Google Pixel 5 4 4 XL, 3 3 XL, LG V40 V30 G6 G8 by Daniel Postle

I bought this to support wired USB barcode scanner connection (with OTG) and power to charge Oppo phone. Asked questions to the Revain community who said it would work. It's not like this. The splitter only allows you to use one function at a time - either a USB barcode scanner or powering your phone. There's no point in having a splitter if you still need to unplug one of the cables to get the other to work.
