Oh boy... Ill vote NO to internal charging, just to avoid that potential problem. Could be small or could make the light not worth buying.. Not worth the trade off, to have IC.. no thanks.
Although I personally don’t like the “color bars” shown in the picture, (kind of garish) the grey color of the body looks good. I’d be happy with that. The silver as in the photos would be okay but I’m tired of black.
I would like to see one in red but it has to solid red, not pinkish. I also really like the colour (magenta?) below but I don’t know if I trust Mateminco to be consistent or even get the colour right. If it’s slightly off it won’t look right.
He just tore down a light (or maybe two) with USB-C charging made by Sofirn that happened to have really high parasitic drain. It’s not inherent to USB-C, since Noctigon K1’s charging circuit has parasitic drain so low that my multimeter can barely even pick it up.
