Test/review of Anker PowerPort Speed 5 2xQC3 A2054

@d_t_a

The 3x 5v/2.4A ports appear to have cable compensation alright (voltage will go up or compensate for higher-resistance cables).
The 2x QC3 ports doesn’t appear to compensate.

This can also be seen on my curves above.

@d_t_a

I notice (using ZY1276 USB meter) that when idle, the top QC3 port voltage is a stable 5.03v while the second QC3 port voltage is a stable 5.00v when no load connected except the USB meter). I wonder if it’s the same on yours?

You cannot expect the two to have exactly same voltage, it is two separate circuit, each with its own regulator.
