I have 3 versions of this light; https://www.aliexpress.us/item/3256804558555808.html
I've used the supplied powerbank feature on all of them just in testing to see if they'll charge my phone or my computer and they do. But, I don't see myself needing such a feature very often.
This design is captivating, but I am not sure about mounting a long wide light on the bike I want a light. Versus a more narrow bodies long light. In the cockpit area of the gravel bike and bikepacking bike I already have a lot going on in the cockpit area. Having the Type C port and battery level indicators on the side is not as convenient for me, versus one that comes straight out the back. I would have to have a cable route out the side and then loop back to my other battery powered items I have mounted in the cockpit area. A port out the back that heads directly to where I keep my bike computer and cell phone would be a lot cleaner in my set-up.
What might be optimal for me is a high lumen light without any batteries that I run a cable to where I keep my Power banks. This keeps more weight out of the handlebar area.
I already have some very powerful round handheld flashlights that I use handlebar "flashlight mounts" I've gone this route for many years now, and this has worked out well. In the most recent lighting technologies, is it better to carry power banks lower on the bike in the frame area then run cables to the items to be powered, or have each item have rechargeable batteries built in.
