I have a brand new Mi Power Bank V2 that supports Output:2* DC 5.1V / 2.4A 9V / 2A 12V / 1.5A MAX18W. The device is not charging. Do I need a special micro USB cord to charge A510 or it won't charge anyway?

    The A510 doesn't use a microUSB connection for charging, though it does look similar. microUSB is 5V, the tablet is 12V, and the pinout is different. Unless your power bank has an adapter for the tablet it won't work even though it handles the right voltage and amperage.

    What kind of adapter is needed? Certain pinage for micro USB? I've seen a charging cable for Acer A510 on AliExpress, but who knows the pinage is correct for charging.

    I don't know if Acer provides a pinout spec for the charging port. The third parties that sell chargers must know though. I'd start by asking the manufacturer of the power bank.

    I've found two cables on Ali.

    The USB convertor with male connector and the micro usb with female connector. Both are for Acer A510. Theoretically this solution may work. What do you think?

    The first one looks like it should work (I don't speak or read Russian so I can't say for sure). I would ask the vendor for the dimensions of the round power socket just to make sure your adapters match. The second one is more problematic. USB specs allow for 500mA at 5V (2.5W), typical fast chargers give 2000mA (10W) instead. The voltage converter built into that will introduce some loss, but even without loss 12V at 10W is less than 1A, which would tend to charge quite slowly. Your power bank could provide more than allowed, but it's better to be safer with the first item.
