Hi,
A few features/quirks that I have noticed with several different PD compatible power banks.
? ? ?All power banks will automatically turn off after a time out period if the load is below a certain level. This is to prevent the battery draining when the power bank it not in use.
? ? ?On one of the PD power banks, it does not instantly negotiate to the trigger setting for its USB-C PD port when using the ON/OFF button on the power bank.
? ? ?On a different PD power bank, if set to 12V, it tends to shut off and restart if there is a high in-rush current when the target load it turned on.
The QMX should not present a high in-rush current, so I would not expect any issues with the power bank being at the trigger voltage before turning on the QMX.
Whilst USB PD and QC provides a handy solution for powering the QMX and other devices, its primary use case is for a charging technology, and the points noted above are not generally a problem.
