I will say this - if the guy goes as far as to remove IC markings then there's a good chance that this is all BS...
UpTone reverse engineered at least 2 other competitor's devices to make their USB Regen product. He even posted the internals of each competator's product on one of his threads and then used some of the competitor's secret sauce parts he found in his new product. It was quite blatant. Maybe he has a guilty conscious and is just obfuscating the parts selection accordingly in their switch product ???
