Any transmitter has the potential to cause problems with a nearby receiver. The transmitter could be a specific RF transmitter, such as LoRa, or anything that emits EMI such as a switching voltage converter or just the microprocessor itself.
A GPS (which is a very sensitive receiver) is prone to interferance when used on devices that also have a transmitter of some form or a fast running processor.
I found the problem with the USB Powerbanks when doing what is normal in this hobby, I was checking the performance of my project;
LoRa when in extreme long range mode is operating at -20dB below noise so the signals it is receiving are very much weaker than in other RF systems.
If your expecting an ABC list of how to build a project using the components you describe, without problems, I doubt you will get it. Its normally a case of building it and checking it all works and interacts the way you want it to.
