Dummy battery for LP-E17 (T7i) for shooting video?

I want to shoot videos using my T7i and I'm concerned about the battery giving out. I've looked at some options for a dummy battery which would replace the LP-E17 battery with a cord out the back that could plug into a USB power pack. But all of the options look like cheaply manufactured things that will break the camera... it's hard to tell what will actually be compatible. Any suggestions for a good product that will allow me to do this?

I needed something similar for astrophotography. I bought one of these

It's not USB, but you just need an 8 volt input. I ended up using one of my 18v drill batteries with a buck converter set to 8.4 volts and it works perfectly.

Looking at Amazon, it looks like there are some available that are USB. If you go that route o would get one of the ones that have two USB plugs, as the power from just one when stepped up to 8.4v might not be quite enough.
