What USB-PD power profiles does the 87W adapter support? Is a 100w/5a rated USB-C cord required, since this exceeds 60w?

I would like to know if this adapter follows the USB-PD specification "power rules" for interoperability with other USB-C devices and cables.

  • From my research and (limited) experience it follows USB-PD 2.0 power rules, but also implements some (allowed) vendor-specific extensions.

    You should be able to use it with a compliant 3A USB-C cable, but power will be limited to 3A/60W with a USB-PSD device that can accept 20v. You'll need a proper 5A/100W cable to make full use of its capabilities.

    I've used it to charge an iPhone 6 with a USB-C to USB-A adapter and measured it providing 5V at ~1.6A (the max an iPhone 6 will draw). I've also used it to charge a RavPower USB-PD capable external battery over USB-C. I don't have any way of directly measuring the power delivered, but I'd estimate it's ~30W.

    If you are curious, the "GTrusted" website has some detailed looks at how various USB-PD devices and chargers interoperate.
