A power bank still detects a connected device if I disconnect USB's VBUS
(1/2) > >>
epigramx:
Do you know of a way to do it - in a standard way - without disconnecting the entire cable? Would disconnecting only GND do it (will try that next if no one answers)?

PS. In case anyone wonders why, it's because I can't change the power bank's model/brand and it doesn't fast-charge itself, if anything else is connected to it.

what about a cable with a built-in switch:

It senses the data lines too.
epigramx:
Another forum suggested to just switch the GND because it will make the other pins float. I guess I'll try that next.

I'd rather avoid that due to cost and space. Plus, it probably only does what I already do (since it's called "power cable").

success, dangling GND made the power bank completely oblivious anything is connected to it.
