All this assuming there didn't exist an exploitable firmware in your USB chargers and powerbanks, which could be used to spread a USB virus or install a payload

  I doubt the USB data lines on a portable charger are connected to anything. When did you last update the firmware for your charger?

    they might have a resistor to indicate how much current is okay to draw, or they might be hooked up to a chip negotiating things like the voltage for the pd protocol, but usually it will be an asic that doesn't even really have firmware

  Are there any $15 battery packs that have exposed firmware?

  Not saying they don't exist, but I've never seen a power bank that had the output data lines wired up to anything.
