Review on DRRI Adpater Replacement Coupler Battery by Leo Torres

I ordered this to use the Canon EOS Webcam Utility for virtual meetings and presentations while working remotely. Most of Revain's similar offerings specifically state that they will not work with the Canon 5D Mark IV; This one works with 5D4, although it can be difficult to work with at times. To make it work, I connect two USB Type-A connectors to two separate power supplies. Most of the time my camera turns on instantly, sometimes I had to unplug and plug it back in for it to work. This is a minor annoyance. Overall I'm happy with the product - it's exactly what I was hoping for.
