I'm mixed on this. I think a unified charging standard is good, but this is late and I personally think USB-C is flawed. I think a connector more like Lightning is better, although I think they likely could have made an even batter cable standard.
Also, USB-C itself is a total mess, with it supporting charging from like very low (like sub 1W) all the way up to what like 200W now? Only not all cables/chargers will support that range, and there's very little way to verify that, not to mention the issues with cables claiming support not actually supporting all the features it claimed.
Also, they needed to make a magnetic/wireless standard as that's quickly going to make the USB-C issue moot and we'll be back to square one, only worse as it won't just be the cables but the chargers themselves as well.
Seems that wireless chargers that support multiple devices and brands is a total crapshoot. Was looking for one that could wireless charge a phone and a smartwatch (both Samsung) and seems like most can't offer that reliably. I found one where multiple reviews said that charger finally worked for them, but then many reported that it failed after months. Even the official Samsung chargers had quite a bit of reviews citing it failing or not working properly.
