Anker doesn’t advertise this but the PowerCore 24K has full-spectrum (3.3-21V) variable voltage (aka PPS) at 5A. This means that it conforms to the specifications of Qualcomm Quick Charge 5. In the video from ChargerLAB shown in an above post, the POWER-Z KM002C device mentions “QC5” in the “PD3.1” section.
This video from ChargerLAB features a nubia REDMAGIC 7S, a phone with a QC5 power setup, charging from various USB PD AC adapters (no portable units were tested.) The phone can be seen taking over 90W from the adapters that have up to 20-21V variable voltage at 5A. With the adapters that either do not have variable voltage or do have it but only up to 11V or 16V, the phone simply sets the adapters to 9V⎓3A.
With the adapters that have the high variable voltage, the POWER-Z device shows that the adapters are set to 19.5V⎓5A, but according to it, the phone is taking ~17V⎓5.4A. There is nothing wrong with the voltage, but that current is over USB PD’s official maximum of 5A from power sources and cables other than the ones that come with the phone. Has anyone tried plugging this or any other QC5-equipped device into the PowerCore 24K using a 5A cable? I would not want to plug one of these phones in only for it to constantly trip the overload protection, or even worse, damage the power bank and/or cable!!!
