Anker Powercore+ 20100 does not charge with Apple 87watt USB-C PD charger

I can confirm that the charger is fine as it charges other phones, tablets and macbooks. I can also confirm that Apple’s 30watt USB-C PD charger charges the Anker Powercore fine.

Is this a known issue?

Most likely it is because the Apple 87W USB-C power adapter has weird power profiles. It isn’t a great general USB-C charger.

The Anker PowerCore+ 20100 takes 5V/3A for its power input. Most USB-C chargers provide 5V/3A, so most work.

Apple’s 87W USB-C power adapter offers 5.2V/2.4A, 9V/3A, 20.2V/4.3A. The 5.2V is likely a large enough deviation from the normal 5V that the Anker power bank refuses the connection. Chargers which offer more than 65W also have to verify the USB-C cable being used supports >3A. The Apple 87W does this by only offering 5.2V/2.4A at the start, then re-advertising its power profiles after several seconds. The re-advertising has been known to cause issues with other USB-C devices, like the Nintendo Switch.

Apple’s 30W USB-C power adapter offers 5V/3A, 9V/3A, 15V/2A, 20V/1.5A. The standard 5V/3A connects without issue to the Anker power bank.
