Rather, the cable became universal and the protocols diverged. But I’m fairly sure the situation will be fixed by the adoption of USB-PD as the ultimate power standard. As all the other standards (QC and else) are including it in their own. And the remaining HDMI devices will be phased out in a decade or so.
Then you’ll need to only care about the wattage rating when charging devices. Seems like future for me.
- necovek 3y agoWhat about bandwidth? There are 10Gbps, 20Gbps and 40Gbps cables, along with "wattage" (really, amperage/current). Both will continue to go up.
- aifooh7Keew6xoo 3y agoIt's worth noting I suppose that newer USB power delivery standards are scaling voltage rather than amperage/current to deliver more power to the device. The pins are specified for 1.25A each yielding 5A and I believe the 5A cable specification came at the same time as 20V with the 100W power delivery specification. Every power increment since then has been a voltage rather than current increment.
- necovek 3y agoGood point, I was aware that newer USB-C PD standard offers bigger power delivery (up to 240W, I think), but I didn't know it was achieved through increased voltage. That means it goes up to 48V DC, so that's certainly curious, thanks!
