| Sep 25, 2020 at 12:06 | comment | added | alsadk | I am trying to use the same concept to figure out the effect on a power bank, my situation is using a USB port which is a part of DVB receiver used to connect HDDs to the receiver for the purpose of charging a power bank that needs a 5V 2A input, I am asking this because after doing this the power bank can be charging but it can not be used to charge devices. I just trying to know if the USB 0.5A current which is lower than the 2A required by the power bank could damage some circuitry. | |

| Sep 25, 2020 at 8:57 | comment | added | alsadk | OK What if a power bank rated at 2A input connected to a USB port 0.5-0.9A output should this harm the power bank or the USB port? | |

Added link to the related question, for completeness - saving people having to google (like I just did) :-)
